摘　　要：长三角地区某污水处理厂提标扩建规模为8.0×10^4 m^3/d,设计出水水质执行《地表水环境质量标准》(GB 3838-2002)准Ⅳ类标准。该工程现状规模为4.0×10^4 m^3/d,根据进水水质分析,将现状"AAO生化池+气水反冲洗滤池"工艺改造为"Bardenpho-MBBR+高效沉淀池+气水反冲洗滤池"工艺。同时,扩建4.0×10^4 m^3/d规模,采用"水解酸化池+改良型AAO生化池+高效沉淀池+气水反冲洗滤池+紫外消毒渠"工艺。文中详细介绍了该工程的改扩建工艺思路、主要构筑物设计参数。The upgrading and expansion project capacity of a wastewater treatment plant(WWTP)in the Yangtze River delta region is 80000 m^3/d,and effluent quality is required to meet classⅣof criteria specified in Environmental Quality Standards for Surface Water(GB 3838-2002).Based on influent quality,original biochemical tanks are upgrading to Bardenpho-MBBR process and high efficiency sedimentation are added.Expansion capacity of the WWTP is 40000 m^3/d and combined process of hydrolytic acidification,modified AAO process,high efficiency sedimentation,air water backwashing filter and ultraviolet disinfection is adopted tank.The process idea and design parameters of the main constructions are also introduced.
