  摘要:

  重庆市某污水处置厂原采取A-A^{2/O为主体的二级处置工艺，此次提标采取改进A-A2/O+高效沉淀池+均质滤料滤池工艺，经由过程对二级生物处置单位进行扩容、增添深度处置单位等体例，有用去除TN、TP、SS，今朝出水水质不变到达一级A尺度。针对该污水处置厂终年进水水质目标（如BOD_{5、COD、SS、TN等）高在一般城市糊口污水的环境，阐发了BOD5、COD、SS、TN等污染物目标去除率较高的缘由，如提高生物池污泥浓度去除BOD5和COD等；针对提标后运转具有的斜管沉淀池季候性藻类和浮渣问题，也提出了改良建议。}}

  Abstract:

  The combined process of improved A-A^{2/O, highefficiency sedimentation tank, and homogeneous filter was adopted to replace the original secondary treatment process of A-A2/O in a wastewater treatment plant(WWTP) in Chongqing. The secondary biological treatment capability was expanded and advanced treatment units were added to effectively remove TN, TP and SS. At present, the effluent quality has reached the first-level A standard. In view of the fact that the influent BOD_{5, COD, SS, TN, and etc. of the WWTP are higher than those of ordinary urban domestic sewage, the possible reasons for higher removal rates of BOD5, COD, SS, TN are analyzed, such as increasing sludge concentration in the biological tank. Suggestions are also put forward to solve the problem of seasonal algae and scum in the inclined tube sedimentation tank after upgrading.}}
