Sewage treatment plant

he removal of organic pollutants and ammonia nitrogen by glwsz buried integrated sewage treatment plant mainly depends on the Ao biological treatment process in the equipment. The working principle is in class A, because the concentration of organic matter in sewage is very high, and the microorganism is in the state of lack of gas. At this time, the microorganism is alkaoorganism, which transforms the organic nitrogen in sewage into NH-N, and at the same time uses organic matter as electronic donor to transform -n into N, and also uses some organic carbon sources and NH-N to synthesize new substances, so class a tank not only has certain The organic matter removal function can reduce the organic load of the subsequent aerobic tank to facilitate the nitrification. Moreover, depending on the high concentration of organic matter in the raw water, the denitrification is completed and the eutrocation pollution of nitrogen is finally eliminated. At level 0, the concentration of organic matter has been greatly reduced, but there are still a certain amount of organic matter and high nh-n.

In order to further oxidize and decompose organics, and at the same time, nitrification can be carried out smoothly when carbonization is completed, aerobic microorganism oxidation tank with low organic load is set at level 0, in which aerobic microorganism and self aerobic bacteria (digestive bacteria) mainly exist, in which aerobic microorganism decomposes organics into C02 and H20, and self aerobic bacteria (digestive bacteria) are beneficial. NH-N in sewage is transformed into -n by using inorganic carbon or C02 in air produced by decomposition of organic matter as oxygen source. The effluent from the o-stage tank is returned to the A-stage tank to provide an electronic acceptor for the A-stage tank, and nitrogen pollution is finally eliminated through denitrification.
