摘　　要：浙江某污水处理厂处理一期常超负荷运行,出水时常不达标,排放标准又显著提高,设计采用对一期减量化运行、生化段改造和二期扩建及深度处理采用集成高效优质工艺等措施,确保出水水质达标。运行效果表明,污水处理厂采用调节+水解酸化+多段强化脱氮改良AAO生化+臭氧接触+高效沉淀+生物滤池+消毒工艺,出水可以稳定达到《浙江省城镇污水处理厂清洁排放指导标准》(准Ⅳ类水标准)。The PhaseⅠproject of a WWTP in Zhejiang province was often overloaded,and the effluent often failed to meet the standard,but the effluent discharge standard is significantly improved.In order to meet the standard,it is adopted that reducing the operating capacity of the PhaseⅠproject,reforming the biochemical section,expanding the PhaseⅡproject and using integrated high-efficiency and high-quality technology in the advanced treatment.The operation result showed that the effluent quality could stably meet Guidance standard for clean discharge of urban sewage treatment plants in zhejiang province(Quasi ClassificationⅣWater standard),by regulation+hydrolytic acidification+multi-stage enhanced denitrification to improve AAO biochemistry+ozone contact+high-efficiency precipitation+biological filter+disinfection processes.
