摘　　要：苏州城东污水处理厂改造前采用初沉池+中心筒曝气池的二级处理工艺,设计规模为4万t/d。随着《城镇污水处理厂污染物排放标准》GB18918-2002的实施,城东污水处理厂出水已不能满足新标准一级A标准的要求,故需对污水处理厂进行升级改造。在充分利用原有构筑物的基础上,最终采用A/A/O+微滤池的工艺改造方案,并增加生物土壤滤池和植物液除臭工艺。实际运行表明,工程设计的工艺完全能使各项出水指标优于一级A标准,且整个污水处理过程中实现了无臭味、低噪音、低能耗。The primary settling tank＋center tube aeration tank,the secondary treatment process was used,the design scale of 40,000 tons/day in the municipal sewage treatment plant in east Suzhou east.With the implementation sewage treatment plant pollutant emission standards of GB18918-2002,the musicipal sewage treatment plant effluent cannot meet the requirements of the new standard A,so there is a great need to upgrade the wastewater treatment plant.Based on the full use of existing structures,the reform scheme,final A/A/O＋ micro-filter technology is used,and the biological soil filter and plant liquid deodorizing process added.The actual operation shows that the designed process completely make the outlet water guality better than standard A,and no odor,low noise,and low power consumption.
