摘　　要：哈尔滨市某污水处理厂现状设计规模为15×10^(4) m^(3)/d,出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准。本次升级改扩建工程在原厂址将污水处理厂总规模扩容至25×10^(4) m^(3)/d,出水水质提标至一级A标准。CASS反应池改造采用CASS+MBBR工艺,重新划分功能区,并增加内回流功能;扩建工程采用多段A2O+MBBR生物池+矩形周进周出二沉池工艺,深度处理采用磁混凝澄清池+紫外消毒工艺。实际运行结果表明,出水水质稳定达标,通过除臭、噪声控制、污泥处理、建筑及景观设计有效化解了邻避效应,可为类似工程提供参考。The current design scale of a wastewater treatment plant in Harbin is 15×10^(4) m^(3)/d,and the effluent is required to comply with the first level B limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The upgrading and expansion project expanded the total scale of the wastewater treatment plant to 25×10^(4) m^(3)/d at the original site,and the effluent quality was upgraded to the first level A limit specified in the discharge standard.The CASS reactor was transformed into CASS-MBBR process,its functional areas were redivided,and the internal reflux was added.The expansion project consisted of multi-stage A2O-MBBR and rectangular secondary sedimentation tank with wastewater peripheral in and peripheral out,and the advanced treatment process was magnetic coagulation clarifier and ultraviolet disinfection.The effluent quality stably met the discharge standard,and the“not in my backyard”issue was effectively resolved through deodorization measures,noise control,sludge treatment and architecture and landscape design.The results aim to provide reference for similar projects.
