Abstract
In southern China,rainfall and topographic characteristics posed greater pressure on the combined drainage system,resulting in more frequent combined sewer overflow,which causes pollution to receiving water bodies.Based on the measured data,the relation between rainfall and overflow in the region was analyzed,and the changes of overflow quantity and water quality were investigated.Then the influence of rainfall and combined sewer overflow on water quality of inland and outer rivers was further analyzed.Finally,the characteristics of regional rainfall,overflow and water quality were summarized,and the suggestions of river water quality control in southern cities during rainy season were proposed.关键词
