Semi underground wastewater treatment plant design reflecting the concept of low carbon and resilience
Chengdong wastewater treatment plant in Taicang city has a treatment capacity of 15×104 m3/d,and adopts semi-underground construction form,which is a leading application case of vibration MBR in China(7.5X104 m3/d).The process of sewage treatment consists of primary sedimentation tank,AAO biological reaction tank,and MBR tank.The effluent water quality is mainly required to meet the Suzhou special emission limit standard.After centrifugal concentra-tion and dehydration treatment(with a moisture content of less than 80％),the sludge is transpor-ted for disposal.The key process design points such as the construction form,general layout,ver-tical layout,wastewater treatment,and sludge treatment of this sewage treatment plant were dis-cussed,while the design concepts and measures of low-carbon,resilience,multi-functional integra-tion,and ecological green were comprehensively considered,which would provide reference for the construction of other large wastewater treatment plants.
