Description
Technical field
The present invention relates to a kind of sewage disposal device and method, the method and apparatus of particularly a kind of two-stage sequencing batch type biological film autotrophic denitrification (CANON) art breading percolate.
Background technology
In traditional nitration denitrification technology, NH has been experienced in the removal of ammonia
4 +-NO
2 --NO
3 -Complete nitrification reaction process and NO
3 --NO
2 --N
2Omnidistance denitrification process, relatively find NO in the complete nitrification reaction process
2 --NO
3 -And omnidistance denitrification process NO
3 --NO
2 -It is the multiple biological process, if this partial reaction is omitted, new biological denitrification process will be saved a large amount of energy consumptions, based on this thinking, Dutch Delf polytechnical university in 1997 is that Rotterdam, NED Dohaven sewage work handles in the anaerobically digested sludge liquid problem and proposed short distance nitration-denitrifying technology notion first, both Sharon technology (Single Reactor HighActivity Ammonia Removal Over Nitrite), SHARON technology is controlled at the nitrite stage with nitrification, compares with traditional complete nitrification denitrification process and can save 25% oxygen-supplying amount and 40% additional carbon.
People such as Broda had inferred under anaerobic be the possibility of nitrite nitrogen and the existence of anaerobic ammonia oxidizing bacteria with ammonia oxidation from the thermodynamics angle in 1977.People such as nineteen ninety-five Mulder have found the Anammox effect in the test of denitrogenation fluidized-bed, a large amount of NH in the test
4 +And NO
2 -Removed simultaneously, (anaerobic ammonium oxidation ANAMMOX) has obtained the confirmation of testing to Anammox first, and ANAMMOX is with NH
4 +-N is an electron donor, NO
2 --N is the autotrophic denitrification reaction of electron acceptor(EA), compares with the full name denitrification, and ANAMMOX technology can be saved 100% additional carbon.
With the combination of short distance nitration-anaerobic ammoxidation technology (SHARON-ANAMMOX) technology, both controlling under the reaction conditions NH
4 +-N is oxidized to NO by ammonia oxidation bacteria
2 --N, anaerobic ammonia oxidizing bacteria is with NO subsequently
2 --N is an electron acceptor(EA), with NH
4 +-N and NO
2 -The proportional N that changes into of-N
2The SHARON-ANAMMOX combined process is compared with traditional complete nitrification denitrification process and can be saved 63% oxygen-consumption and 100% additional carbon.The way of realization of the SHARON-ANAMMOX combined process of report is to realize the nitrosification denitrogenation realizing Anammox in the apposition growth system in the suspension growth system.People such as Hippen in 1997 utilize and realized realizing short distance nitration-anaerobic ammoxidation technology in the blodisc treating refuse percolate process in reactors, both Full Autotrophic Ammonium Removal Process (Completely autotrophic nitrogen removal over nitrite, CANON) technology, compare with SHARON-ANAMMOX technology, CANON technology can realize short distance nitration and Anammox in single reactor.People such as Sliekers study CANON technology in the biosystem of suspension growth, and for the biosystem of apposition growth, DO diffuses to till the microbial film aerobic layer in the hierarchy of control, under the limit oxygen condition, the aerobic layer microbial film utilizes aerobic ammonia-oxidizing bacteria that ammonia nitrogen is oxidized to nitrite, anaerobic ammonia oxidizing bacteria is that electron acceptor(EA) is converted into nitrogen with ammonia nitrogen with the nitrite in the biological membrane anaerobic layer, the oxygen consumption of entire treatment technology minimizing 63% and 100% additional carbon.
Sequencing batch biofilm reactor (Sequencing batch biofilm reactor, SBBR) be at the filled formation microbial film of SBR basis upslide, simultaneously according to the sequence batch (operation scheme of SBR, make activated sludge process and biomembrance process process combined equal to put forward first in 1992 subsequently Chinese scholars and carried out big quantity research by Wilderer.SBBR technology has realized reaching running balance in same reactor inner suspension growth microorganism and apposition growth microorganism, microbe species and microbial biomass increase greatly, have good biological carbon and phosphorous removal characteristic, and surplus sludge volume is few, advantage such as sludge settling property is good.
Percolate is a kind of organic components complexity, high ammonia nitrogen, low C/N, the organic waste water of biological treatment desired nutritional proportional imbalance, the prior biological denitrification treatment technology is limited to the removal effect of percolate ammonia nitrogen, adopts pre-treatment (as the ammonia stripping more, technologies such as coagulation)-anaerobic biological treatment is (as acidication, technologies such as UASB)-aerobe handles (as bio-contact oxidation etc.), binding film bio-reactor simultaneously, technologies such as reverse osmosis technology.Relevant patent as: (1) two-stage UASB+A/O art breading percolate method (Peng Yongzhen, ZL200620023291.1); (2) flocculation-ammonia stripping-UASB-catalytic oxidation-MBR-nanofiltration treatment process (Ceng Shengxue, CN1872745A); (3) MBR art breading percolate method (Han Demin, ZL200620001528.1), (Liao Zhimin, CN1970474A), (Chen Jian, CN1528686); (4) the osmosis filtration technology (Han Demin, ZL200620001529.6), (Liao Zhimin, CN1736904).
And based on the treating refuse percolate technology of aerobic nitrification-Anammox denitrogenation, relevant patent has: and (1) Anammox and denitrification synergistic denitrification method (Zhou Shaoqi, CN101007684A); (2) split type aerobic nitrification-Anammox technical finesse percolate method (Liang shanbo and Zhu yingtai, CN1769211A).Above-mentioned two kinds of methods have been utilized similar SHARON-ANAMMOX technology, efficient removal of ammonia and nitrogen under the control reaction conditions.
