摘要
Abstract
The wastewater treatment plants(WWTPs)are facing the problem of low carbon source at home,and the cost of adding carbon source is increasing due to the increasingly strict discharge standard of deep nitrogen and phosphorus removal from wastewater in different regions.In AAO process,there is competition for carbon source between biological phosphorus removal and denitrification nitrogen removal.The cost of BOD5 reagent to remove 1 mg/L phosphorus by biological phosphorus removal is 0.154 yuan/m3,the BOD5 cost of denitrifying nitrogen removal is 0.038 yuan/m3,so the BOD5 consumption of biological phosphorus removal can be used for denitrifying nitrogen removal of 4 mg/L.The total cost of coagulant reagent and the treatment and disposal cost of the increased amount of sludge for chemical phosphorus removal is 0.040 yuan/m3,therefore,the cost of biological phosphorus removal is 3.85 times of that of chemical phosphorus removal.For advanced nitrogen and phosphorus removal from low carbon source wastewater,AOAO+chemical phosphorus removal process,which uses chemical phosphorus removal instead of biological phosphorus removal,has the advantage of low operation cost.关键词
