南昌市区初期雨水污染研究与防治对策

随着城市污水和工业废水等点源污染控制水平的提高，城市非点源污染的严重性日益表现出来，是仅次于农业非点源污染的第二大污染源。降雨后在形成的地表径流中污染物的浓度与未经处理的城市污水基本相同，成为我国城市水体水质恶化的主要原因之一。在充分调查研究之后，分析了南昌市区非点源特征，探讨了非点源污染控制的主要对策和措施，以便为该地区城市非点源污染供科学依据。

Initial Period Rain Water Pollution Studies and Control Measures in Nanchang Urban

With the city sewage and industrial wastewater from point sources of pollution control level increases,the city non-point source pollution gravity displays day by day,which is second only to agriculture non-point source pollution and becomes the second largest source of pollution.After the formation of rainfall runoff,the concentration of pollutants is basically the same as untreated sewage in the city and becomes one of main reasons which make our country city water body water quality worsen.After the full investigation and study foundation,analyzing the Nanchang urban district non-point source characteristic,discussed the major policies and measures of the non-point source pollution control,in order to supplies the scientific basis for this local city non-point source pollution.
