Background technology
In sewage treatment project, biological denitrification process is by nitrification ammonia nitrogen to be converted into nitrate nitrogen, by the denitrification technology nitrate nitrogen being converted into nitrogen again overflows from water, because nitration reaction is to carry out under good oxygen condition, anti-nitration reaction is to carry out under anaerobic state, in order to obtain the good removal organic pollutant and the effect of denitrogenation simultaneously, generally adopt aerobic in conjunction with anaerobic technology.
A kind of is that anaerobic-anoxic-aerobic process (Anaerobic-Anoxic-Oxic) is the abbreviation of anaerobic-anoxic-aerobic biological denitrification dephosphorization process.Hereinafter to be referred as A
2/ O technology, its general flow chart sees Fig. 1 for details, sewage s is introduced into equalizing tank 1-1, be transported to anaerobic pond 1-2 by water pump lifting again and then enter aeration tank 1-4 through anoxic pond 1-3 again, aeration tank 1-4 water outlet flows into settling tank 1-5, settling tank 1-5 realizes that the supernatant liquor (clear water) after the mud-water separation flows out from system, the mud n after the separation is back to anaerobic pond 1-2; In order to realize the purpose of denitrogenation dephosphorizing, the nitrification liquid xhy (sewage) of process nitration reaction among the 1-4 of aeration tank need be back to anaerobism (anoxic) pond and carry out anti-nitration reaction in operational process, the nitrification liquid xhy of backflow generally is 2 to 4 times of sewage s water inlet.A
2The advantage of/O technology is that the nitre attitude oxygen that makes full use of in denitrification process in the nitrification liquid comes oxidation BOD
5, reclaimed the oxygen requirement of part nitration reaction, the basicity that anti-nitration reaction produced can partly compensate the basicity that nitration reaction consumes, therefore to contain the not high municipal effluent of nitrogen concentration can be not in addition exogenously added alkali regulate HP.This technology is the simplest dephosphorization and denitrification process in system, and total hydraulic detention time is less than other similar technology; Its anaerobism (anoxic) aerobic reaction pond branch is arranged, so its dephosphorization and denitrification effect is higher and stable.A
