A kind of domestic waste water treatment agent that contains activated silica
Technical field
The present invention relates to a kind of waste water conditioner, particularly relate to a kind of domestic waste water treatment agent that contains activated silica.
Background technology
We can produce very many family domestic waste waters in life.In these family domestic waste waters, a large amount of pollutents is arranged.Wherein nitrogenous compound is as nitrite nitrogen, nitrate nitrogen, inorganic salt nitrogen, dissolved nitrogen etc., caused in family domestic waste water total nitrogen higher, and in domestic waste water, total phosphorus content is also very high in addition.These are all the main sources of the pollutent in domestic waste water.Adopt certain method to reduce total nitrogen and the total phosphorus content in family domestic waste water, be one and need to have set about immediately the problem that will solve.
Summary of the invention
The technical problem solved: total nitrogen value value and the too high problem of total phosphorus value in family domestic waste water.
Technical scheme: the invention discloses a kind of domestic waste water treatment agent that contains activated silica, the domestic waste water treatment agent is comprised of according to weight ratio following composition: poly-ferric sulfate chloride is that 1~3 part, activated silica are that 2~4 parts, phenylalanine are that 3~5 parts, Isoleucine are that 5~6 parts, alum are that 6~8 parts, asbestos are that 4~7 parts, deionized water are 145~165 parts.Wherein, owing to having added a certain amount of phenylalanine and Isoleucine, certain synergy can occur in two seed amino acids and poly-ferric sulfate chloride, activated silica, alum, asbestos, make carrying out water treatment, can be wrapped up by nitrogen-containing pollutant and containing phosphor contaminant, put and assemble, and then deposited phenomenon occurs.Be gathered in the domestic waste water bottom, clarified domestic waste water.
The preparation process of the domestic waste water treatment agent that contains activated silica is as follows: each moiety of at first getting treatment agent: poly-ferric sulfate chloride is that 1~3kg, activated silica are that 2~4kg, phenylalanine are that 3~5kg, Isoleucine are that 5~6kg, alum are that 6~8kg, asbestos are that 4~7kg, deionized water are 145~165kg.Each composition evenly is fed in deionized water, is the domestic waste water treatment agent that contains activated silica after stirring.
Beneficial effect: the waste water conditioner that contains activated silica that the present invention prepares can significantly reduce total nitrogen value and the total phosphorus value in family domestic waste water, and the total nitrogen value is down to 0.6~0.9mg/L from 86mg/L, and the total phosphorus value is reduced to 0.7~0.9mg/L from 57mg/L.
Embodiment
Embodiment 1
Poly-ferric sulfate chloride is that 1kg, activated silica are that 4kg, phenylalanine are that 5kg, Isoleucine are that 5kg, alum are that 8kg, asbestos are that 4kg, deionized water are 165kg.Each composition evenly is fed in deionized water, is the domestic waste water treatment agent that contains activated silica after stirring.
Embodiment 2
Poly-ferric sulfate chloride is that 2kg, activated silica are that 2kg, phenylalanine are that 3kg, Isoleucine are that 6kg, alum are that 6kg, asbestos are that 6kg, deionized water are 155kg.Each composition evenly is fed in deionized water, is the domestic waste water treatment agent that contains activated silica after stirring.
Embodiment 3
Poly-ferric sulfate chloride is that 3kg, activated silica are that 3kg, phenylalanine are that 4kg, Isoleucine are that 5kg, alum are that 7kg, asbestos are that 7kg, deionized water are 145kg.Each composition evenly is fed in deionized water, is the domestic waste water treatment agent that contains activated silica after stirring.
The domestic waste water Processing Test
Get 3 parts of domestic waste waters, every part is 1000g, is same water quality.3 parts of Determination of Total Nitrogen in Waste Water values are 86mg/L, and the total phosphorus value is 57mg/L.The waste water conditioner addition of embodiment 1, embodiment 2, embodiment 3 is the 1wt% of waste water weight.Join respectively in waste water, standing after stirring 10min, time of repose is 3h, gets supernatant liquor after 3h, measures total nitrogen value and total phosphorus value:
? | Before processing | After embodiment 1 processes | After embodiment 2 processes | After embodiment 3 processes |
Total nitrogen value (mg/L) | 86 | 0.7 | 0.9 | 0.6 |
Total phosphorus value (mg/L) | 57 | 0.8 | 0.7 | 0.9 |
From table, result can be found out, the domestic waste water that the domestic waste water treatment agent that contains activated silica of the present invention was processed, and the total nitrogen value is down to 0.6~0.9mg/L from 86mg/L, and the total phosphorus value is reduced to 0.7~0.9mg/L from 57mg/L.Can be applied in wastewater treatment.
