[Detailed explanation of the Invention]

[Purpose of the Invention]

[Technical area of this invention and the Prior Art in this Area]

<35> This invention relates to treatment of effluent discharged from intensive livestock industries.

<36> The effluent discharged from intensive livestock industries is a mixture of excrement and urine.

<37> The effluent consists of mostly solid substances in high concentrations, such as excrement, thereby preventing the growth of microorganism. This precludes the application of ordinary treatment method using microorganisms.

<38> For an instance, effluent discharged from hogs, being excrement and urine has BOD of 15,000-20,000ρρm, <39> The effluent consists mostly of solid substances with minimal oxygen content. Consequently without treatment, micro-organisms can not survive; treatment of solid matter takes considerable time.

<40> Therefore, a more efficient way to treat the liquid after it has separated from solids is to apply the oxidation method through contact with microorganisms.

<41> Hog wastes are the hardest to treat among all farm animal wastes, as it contains a fine sludge, making separation of solids and liquids difficult.

<42> Presently, centrifuge, filter-pressing, pressure floating methods are used to separate solids and liquids. However, under the current centrifuge method, solids under a certain size still cannot be separated entirely.

<43> The filter-pressing method is complicated and expensive in both facility and labour required; despite this it cannot separate solid substances below a certain size.

<44> The pressure floatation method is expensive to build, difficult operate, has high operating costs and causes public nuisance due to large amounts of noise generating by an air blower during oxidation and after separation of solids and liquid.

<45> The technology related to this invention purifies effluent using microorganism, "The treatment system of effluent" (Korean patent No. 10-0226213) using media to allow microorganisms to habit invented by applicant of this invention.

<46> Although the media in the above methods make use of aerobic microorganisms, problems arise due to their complicated systems of re- washing of media, returning of sludge and ventilator.

<47> To resolve this problem, "The aerobic treatment method of effluent and treatment tank " (The Korean patent No.10-0409056) using aeration device in water(120) and separator (110) for effluent treatment was invented by the Applicant of this invention.

<48> The existing methods contain a problem of low purifying effect due to aeration in a single treatment tank.

<49> the existing methods contain a further a problem in that there are no steps for the separation of floating solid substances in effluent, or its method is ineffective.

[The technological aim of the invention]

<50> The present invention aims to solve the problems arising from the current effluent disposal methods by pumping micro-bubbles with diameter 1-50 jam to effluent in order to separate solids from the liquid, and then treatment of the liquid. <51> The invention further aims to treat liquid separated from floating solids by aeration and to enhance the effectiveness of treatment methods using the micro-bubble and hollow media.

<52> Further, by supplying ozone containing micro-bubbles to the aeration tank, another aim is to break down polluting hormones as well as other substances found in animal excrements.

<53> The effluent treatment process will be made more effective by using an ultraviolet lamp which will be used to break down residual ozone

<54> Noise pollution will be kept to a minimum through use of a small capacity air pump.

[Composition of Invention]

<55> This invention relates to the treatment of effluent discharged from intensive livestock industries.

<56> This invention will first separate solids from the effluent by use of micro-bubble generator and then treat the remaining liquid.

<57> The liquid will then be treated by using media and micro-bubbles.

<58> The invention breaks polluting hormones and the animal excrement bilirubin by providing micro-bubble containing ozone to the aeration tank. <59> Furthermore, an ultraviolet lamp will break down any residual ozone.

<60> The structure of this invention is as follows: the effluent is pumped inside; the first micro-bubble generator connected to an air blower and installed on the lower part; at one end of the of the discharge pipe is the solid/liquid separation tank; the other end of the discharge pipe is connected to the central pipe, which carries the discharge from the solid/liquid separation tank to inside of the invention, this is located on the interior where an exit tube of the solid/liquid separation tank is installed.

<61> In the middle of inside installed center pipe, the other side of the exit pipe of disposal effluent connected to the center pipe disposal water of the solid liquid separating tank flows to the inside through the center pipe, inside of the center pipe installed returning pipe which of one side connected to the solid liquid separating tank.

<62> On the other side of the returning pipe connected to the air blower the precipitate in bellow make returning to the solid liquid separating tank like thus precipitating tank.

<63> Connected to the precipitating tank, disposal water ended precipitating process flows to the inside in which thousands of media are packed in below of the aeration tank installed the second micro-bubble generator connected to the air blower, <64> The disposal water of the aeration tank flows to the inside, installed in bellow the third micro-bubble generator connected to the ozonizer and the entry of ozone tank which micro-bubble containing ozone provided inside.

<65> Aerated disposal water in ozone tank flows inside, where installed ultraviolet lamp, and consists of ultraviolet tank installed the exit of the purified water on one side. Disposal water of the aeration tank flows to the inside.

<66> The technical aspects of this invention are described further on the attached diagram .

<67> The diagram is attached only as an explanatory aid for the invention, and its intrinsic worth is not limited to merely what is contained in the diagram.

<68> The effluent(lOO) of intensive livestock industry flows to the inside of the solid/liquid separation tank(lθ), in which the ventilation mechanism (60) is connected to the first micro-bubble generator (12) on the lower part of it, also installed on the lower part one end of the effluent discharge pipe. (13) <69> As shown in Figure 2, the ventilator(60) is connected to outside ,the ventilator (60) and the first micro-bubble generator(12) are connected through the first connecting pipe(12a).

<70> Just, through the first connecting pipe(12a) the air from ventilator provides to the first micro-bubble generator (12)

<71> To flow the effluent(lOO) into the inside, preparing collecting pipe or collecting tank to collect the effluent(lOO) from intensive livestock industries then the effluent providing piped 1) consist of one exit pipe is connected to the solid liquid separating tank(lθ), or each pipe of disposal effluent can be connected to the solid liquid separating tank(lθ).

<72> The first micro-bubble generator(12) provides micro-bubble from bottom to the top of the solid liquid separating tank(lθ) due to transfer floating solid of the effluent(lOO) to the surface.

<73> The first micro-bubble generator(12) consists of the motor(12c), the imρeller(12d), the rotating axis(12e), the spraying nozzle and slit formed slit wall(12g) as shown on the figure 6 together with ' micro- bubble solving equipment' which Korean patent No.10-0465755 by applicant of this invention.

<74> In this time, the number of impeller(12d) is not limited as two, it can be as one , three and so on. <75> Also, even not showing as figure but it can be consist of together with 'micro-bubble solving equipment' which Korean patent No.10- 0465755 by applicant of this invention.

<76> Normally the effluent(lOO) of hog farm excretes together with feces and urine and its floating solidOO) is 18,000-20,000mg/ 1 .

<77> In this time, passing the micro-bubble diameter l~50 //m through the first micro-bubble generator (12) described above, the floating solid adapted to the micro-bubble and make it floating.

<78> The floated floating solidOO) can be removed by hand work, or if prepared ,send to the fermenting tank(80) connected to the solid liquid separating tank(lθ) as shown on figure 4.

<79> The methods of sending the floating solid (90) to the fermenting tank(80) are by hand work or have flow the floating solid (90) naturally to the fermenting tank(80)which built next to the solid liquid separating tank(10)and make the open wall between the fermenting tank(80) and the solid liquid separating tank(lθ).

<80> Also, installed the solid removing equipment(14) at top of the solid liquid separating tank(lθ), floating solid can be flown to the fermenting tank using the solid removing equipment(14) <81> The solid removing equipment(14) consists of motor(14a), rotating roller(14b), belt(14c) connectable to the rotating roller(14b),the wing(14d) removing the solid are installed to the belt(14c)and which can be used.

<82>also, making the solid exit(15) at the upper part of the solid liquid separating tank(lθ) and removed solid to the wing(14d) can be eliminated through the solid exit(15).

<83> The precipitating tank(20), one of essential part of this invention, installed the next to the solid liquid separating tank(lθ), is built to get the first treated effluent(lOO) from the solid liquid separating tank(lθ) through effluent discharge pipe(13).

<84> In this time, the precipitating tank(20) as shown on the figure 2 became slope at bottom of the wall, installed centric pipe emptied in middle and is connected , and its effluent discharge pipe(13) is connected to the centric pipe(21).

<85> To precipitate the solid at the center of the precipitating tank(20) slope shaped hunch can be installed inside of the precipitating tank(20).

<86> Just, the effluent(lOO) of the solid liquid separating tank(10 )became to flow inside of the precipitating tank(20) through the centric pipe(21), but it makes to gather in the middle. <87> The reason for installing one side of the effluent discharge pipe(13) to the lower part of solid liquid separating tank(lθ) and the other side connects to the centric pipe (21) of the precipitating tank(20) is that the first treated effluent (100) have sent to the precipitating tank(20) due to contain small quantity of solid after separated solid and liquid in the solid liquid separating tank(lθ).

<88> Inside of the centric pipe of the precipitating tank(20) installed the returning pipe(22) through which the solid of the precipitating tank(20) return to the solid liquid separating tank(lθ).

<89> The returning pipe(22) installed up to the bottom of the precipitating tank(20) in the centric pipe, the upper part of the returning pipe(22) connected to the upper part of solid liquid separating tank(lθ).

<90> And, the returning pipe(22), at the lower part of it, connected to the blower(22a) which connected to the ventilator(βθ)

<91> Just, the air from ventilator (60) through air pipe(22a) is provided to the lower part of the returning pipe (22) and moved to the upper part of the returning pipe(22), in this time the precipitate return together to the solid liquid separating tank.

<92> This is the principle of the air pump, blowing air to the lower part of the pipe filled with liquid ,the air goes to the upper part, at same time the part of pipe with mixed air and liquid become lower pressure than the bottom part of liquid so that the liquid not containing air push the liquid containing air which has lower pressure .

<93> The purpose of the sediment tank(20) formed like above is that after separating liquid and solid from liquid solid separating tank(lθ) if the solid left in the disposal effluent(lOO) making ppt and eliminating entirely.

<94> The centric pipe(21) is installed in the middle of sediment tank(20)and the first treated effluent(lOO) from the liquid solid tank (10) flows to the centric pipe(21), the first treated effluent (100) in the centric pipe flows to the low part from which flows to outside of the centric piρe(21) and make it elevate to upper part and make the solid precipitating easily.

<95> Therefore, the lower part of the centric pipe(21) is not located on the bottom of the sediment tank(20) but apart some.

<96> The exit of sediment tank(23) is formed at the upper part of the sediment tank for treated effluent(lOO) finished precipitating process to flow to the next step.

<97> The filter(23a) is installed at the exit of sediment tank(23) to prevent the flowing solid (90) goes to the next step. <98>The aeration tank(30), one of essential part of this invention, is connected to the exit of sediment tank(23) that the disposal effluent(lOO) finished precipitating process is going to flow to the inside.

<99> The thousands of media are filled the inside of aeration tank(30) of which at the lower part installed the second micro bubble generator(32) connected to the ventilator(60).

<100> the second micro bubble generator(32) is the same structure, and form the first micro bubble generator(12).

<101> The way filling thousands of media at the inside of aeration tank(30) is various.

<102> As showing on the figure, after forming the shape(33) of the iron net, stainless net or pvc net, the media put into the shape(33) or put into inside the square shape(33) formed with pore upper and lower part of it .

<103> In this time, it is better to install the shape(33) at the place of 50cm from the aeration tank(30) and the upper of the shape(33) is going to be at 30cm below of water.

<104> The media (31) is empty of inside of small body which discard bottle or container can be used; the plastic yogurt bottle is the best. <105> In this time, to escalate the activity of the microorganism make hole(31a) on the bottom of the yogurt bottle so that the micro-bubble providing more.

<106> This configuration is that from the second micro bubble generator (32)produce the bubble diameter 1-5 im, and this bubble escalate through the media(31) and provide the air to the microorganism residing in the media(31).

<107> The aeration tank(30) formed like this, purifies the contaminant in treated effluent(lOO) separated the solid from the sediment tank(20) by microorganism through contact oxidation aeration.

<108> In this time, from the second micro bubble generator(32) provide oxygen by the bubble, the microorganism purifies the disposal water using this oxygen.

<109> It is better that the media are filled with indifferently when the media(31) formed ρore(31a) at bottom stands strait the micro- bubble goes through inside much, then much oxygen provide , so that the aerobic microorganism can live vividly and this microorganism oxidate the contaminants, so that effluent(lOO) become purified.

<110> Also, in the media(31) layed as side the oxygen cannot be provided therefore anaerobic microorganism live inside of the media(31), by the anaerobic fermentation the contaminant in the effluent(lOO) become purified.

<111> In the media stands leaning as 45° ,30°, 15°, the middle of aerobic and anaerobic microorganism live and that can purify the effluent(lOO).

<112> Like this, using as media(31) formed hole(31a) at bottom of yogurt bottle, so this media installed indifferently that whole range of microorganism with aerobic, anaerobic and middle of both live together, then the ability of treatment is much upgrade.

<113> These various microorganism is occurring naturally, or put them prior in the media(31) and install that later to grow microorganism .

<114> And also, at one side of the aeration tank(30) the exit of aeration tank(34) is formed to discharge the disposal effluent(lOO).

<115> One of the essential part of this invention, the ozone treatment _>tank(40) is that the disposal effluent(100)aerated firstly in the aeration tank(30) flow inside , and installed the third micro-bubble generator(41) with aeration tank(30).

<116> The third micro-bubble generator(41) can be used that the same as the first micro-bubble generator(41) explained as above. <117> In this time ,due to the third micro-bubble generator(41) connected to the ozonizer(42) from which produce micro-bubble containing ozone and provide to the inside of ozone treatment tank(40).

<118> In the ozone treatment tank(40) the bilirubin( yellowish red color) and PCB in the disposal effluent(lOO) flowed from aeration tank(30) are decomposed by oxidation.

<119) Due to discharge the treated effluent(lOO) decomposed bilirubin and pvc by oxidation ,the exit of ozone treatment tank(43) is formed on one side of the inner part of ozone treatment tank(40).

<120> The ozonizer(42)can be used with the equipment prescribed on the applicant of this invention registered the Korean No.10-0509813' the equipment of resolving ozone into water as high efficiently and the method to use it.

<121> Also, these ozonizer(42) known as publicly precise description is omitted.

<122> Through these ozonizer(42) and the third micro-bubble generator(41) provides micro-bubble to inside of ozone treatment tank(40),for instance of which ozone 5-15 vol.% oxygen 85-95 vol.% can be used.

<123> The reason for providing the micro-bubble containing ozone to inside of the ozone treatment tank(40) is that beside simply purify the effluent(lOO) and decompose the substance like bilirubin and various environmental hormone in feces and urine of intensive livestock industries. <124> In this time , several of the aid aeration tank (70) can be installed between the aeration tank(30) and the ozone treatment tank(40) as showing on the figure 4.

<125> This is that if the house of intensive livestock industries big enough, the speed of flowing and exiting of treated effluent(lOO) into the aeration tank(30) become fast, in this case due to the insufficient aeration make difficult of purifying the disposal water.

<126> Therefore, the aid aeration tank(70) like these can be formed one room or more according to the exit speed and quantity of the disposal effluent (100).

<127> At the inside of the aid aeration tank(70) ,the media(31) and the aid micro -bubble generator(71) are installed as the same as the aeration tank(30).

<128> Also, the aid micro-bubble generator(71) is connected to the ventilator (60), at one side of the aid aeration tank(70) the exit of aid aeration tank is formed to discharge the aerated disposal water.

<129> And , the ventilator(βθ) and the aid micro -bubble generator (71) are connected through the aid connecting pipe(71a), installing the aid controlling valve(71b) at one side of the aid connecting pipe(71a) is effective. <130> One of essential part of this invention, the ultraviolet treatment tank(50) inside of which flown the disposal effluent(lOO) finishing decompose process of bilirubin and environmental hormone in the ozone treatment tank(40) and installed ultraviolet lamp(51) which sterilize the treated effluent(lOO) and decompose the left ozone in the treated effluent(lOO).

<131> And on one side installed the exit(52) of the purified water finishing the treatment process.

<132> In this time, the ultraviolet wave is 253-255nm so that decompose the left ozone and pollutants and better to install two of the quartz ultraviolet lamp(51) which produce 253.7nm ultraviolet ray.

<133> If the wave for decomposing ozone and the wave for pollutants are different several ultraviolet lamp(51) generating different rays can be installed.

<134> And on one side of the ultraviolet treatment tank (50) installed the exit(52) of the purified water to discharge the disposal effluent(lOO) finishing treatment process.

<135> Like above, the treatment facility of intensive livestock industries effluent can be constructed with variety shape like concrete structure or tank beside tank structure. <136> Also, the first micro-bubble generator(12) and the ventilator(βθ)^' are connected to the first connecting pipe(12a), the second micro-bubble generator(32) and the ventilator(ΘO) to the second connecting pipe(32a), the third micro-bubble generator(41) and the ventilator(60)connecting through the third connecting pipe(41a), and on each connecting pipe installed each control valve ie, the first connecting pipe(12a) to the first control valve(12b), the second connecting pipe(32a) to the second control valve(32b), and the connecting pipe(41a) to the third control valve(41b), thus supplying air can be controlled.

<137> And the supplying air can be controlled by the control valve of supplying piρe(22b) installed to the air supplying piρe(22a) connected to the ventilator(60).

<138> Like this ,it is better that the first micro-bubble generator(12) ,the second micro-bubble generator(32),the third micro-bubble generator(41) and the air supplying pipe(22a) are connecting to the one ventilator. But it is not limited but can be connected to each ventilator(βθ). <139> Following is the explanation of this invention structured like above.

<140> Seeing the process of the treatment of intensive livestock industries effluent, first the effluent(lOO) including urine and feces flow to the solid liquid separating tank (10).

<141> When the effluent(lOO) was flown into the solid liquid separating tank (10), moving the first micro-bubble generator(12) and micro-bubble

20

SUBSTITOTE SHEET (RULE 26) supplies from lower to the upper part of the solid liquid separating tank (10).

<142> In this process the floating solid(90)in the effluent (100) combine with micro-bubble gathers on the upper part, the gathered floating solid (90) send to the fermenting tank(80) through solid removing tool(14) or by hand work.

<143> Or as describing above, made the upper wall lowered between the solid liquid separating tank (10) and the fermenting tank(80) the floating solid(90) mounting on the wall eliminates naturally into the fermenting tank. (80).

<144> The disposal effluent(lOO) in the solid liquid separating tank (10) moves to the sediment tank(20) through the exit of disposal water(13), precipitating the remained solid in the sediment tank(20) through the returning pipe the precipitated floating solid transfer again to the solid liquid separating tank (10) and the disposal water finished precipitating process flows to the aeration tank(30).

<145> The aeration tank has the first aeration process through media(31) and micro-bubble produced from the second micro-bubble generator (32) installed inside and purified by contact oxidation.

<146> Once aerated treated effluent(lOO) flows to the ozone treatment tank, (40) because the third micro-bubble generator (41)and the ozonizer(42) are installed at the ozone treatment tank (40) in which bilirubin and pollutants are processed to oxidative decomposition by oxygen containing ozone.

<147> The treated effluent(lOO) finished oxidative decomposition of bilirubin and pollutants in the ozone treatment tank(40) flows into the ultraviolet treatment tank(50).

<148> The ultraviolet lamp(51) is installed at ultraviolet treatment tank, this ultraviolet lamp(51) decompose the ozone contained in the treated effluent flown from the ozone treatment tank(40).

<149>Also, by using the wave of the ultraviolet lamp(51) the remained pollutants can be sterilized.

<150> The purified water finished the process of sterilizing and ozone decomposing discharge through the exit of purified water.(52)

[ The effect of the invention]

<151> According to this invention , providing micro -bubble diameter 1- 50 _IM to the floating solid in disposal water the floating solid can be decomposed easily in the effluent.

<152> Instead used big ventilator in contact oxidation method, using small ventilator almost noiseless treatment facility can be provided. <153> Using the micro-bubble generator able to dissolve high concentration ozone in water, owing to dissolve high concentration ozone in treated effluent, the treatment method by ozone is provided.

<154> Especially, provided ozone able to decompose pcb and environmental hormone effectively.

<155> Also, the facility is simple, because of dissolving micro-bubble diameter 1-50 [M in disposal water the quantity of dissolved oxygen is high therefore the efficiency of treatment is high up.

<156> And purifying by aeration the disposal water separated floating solid , using the media with empty space inside and micro-bubble, the efficiency of treatment is high up.

<157> The treatment facility of high efficacy be provided that using the ultraviolet lamp decomposes the remained ozone.
