Abstract
The combined sewer overflow(CSO)is one of the important causes of the malodorous black water,based on the specific conditions in China,CSO can be controlled by constructing"sewage interception pipeline+Combined system storage tank".regulating storage tanks are widely used in controlling CSO,by combining the engineering project example of Naping River Basin management in Nanning city,the design experience is summarized,and the comparison and determination of regulating storage tank capacity,single-layer and double-layer regulating storage tank form,pool body flushing mode and gas deodorization mode were summarized from the aspects of rainfall characteristics,current pipe network,implementation environment and project investment.Monitoring the operation of the storage tank of the project,analyzing the reduction effect of the storage tank on the combined overflow pollution,it shows that the construction of the storage tank can systematically increase the overall interception ratio of the interception system,reduce the overflow frequency,reduce the occurrence of CSO,and enhance the toughness of the entire drainage system关键词
