Buried Medical sewage treatment equipment

Currently the sewage treatment process used at home and abroad, many of them can be divided into two active sludge and biofilm, our common ordinary aeration, oxidation ditch, A / B Act, A2 / O method belongs to former bio turntable, contact oxidation latter. Buried Medical sewage treatment equipment principle is A level, due to the high concentration of organic matter sewage, microbes in a hypoxic state, this time for the microbes and micro-organisms, they will sewage organic nitrogen is converted decomposed into NH3-N, while taking advantage of organic carbon as an electron donor, the NO2-N, NO3-N is converted into N2, and also use part of the organic carbon and NH3-N synthesis of new cellular material. So A-level pool not only have a certain surface removal function, reduce the subsequent aerobic pool organic load. It was in favor of nitrification, but also on the presence of high concentrations of organic matter in the raw water, complete denitrification, the eventual elimination of nitrogen eutrophication. In the O level, due to the concentration of organic matter has been greatly reduced, but the sewage treatment facilities is still a certain amount of organic matter and high NH3-N exists. In order to further oxidation and decomposition of organic matter, while carbonation completed cases, nitrification can proceed smoothly. Set a low organic loading aerobic biological contact oxidation pond at O ??level. O level in the main pool for aerobic microorganisms and bacteria from oxygen Which aerobic microorganisms to decompose organic matter into CO2 and H2O;. Get bacterial decomposition of organic matter produced by the use of inorganic carbon or CO2 in the air as a nutrient source from oxygen, sewage The NO2-N, NO3 - NO level tank effluent flows to A-level pool. Provide electron acceptor for the A-level pool, through denitrification eventually eliminate nitrogen pollution.
