布吉河流域污水截流倍数与河流水质关系研究

Research on the Relationship Between Sewage Interception Ratio and Water Quality in the Buji River Basin

截流倍数与河流水质关系研究中主要影响因素有降雨径流条件、城市分流制比率、污染物入河量、河流水力条件及水质目标等。面源污染作为雨季随径流进入河道的污染物,是需研究的一个重要因素,在目前合流制(或混流制)占较大比例的排水体制下,面源污染占点源污染的比例小,但由于其突发性,也不容忽视。

The main factors that need to be concerned in the research on the relationship between sewage interception ratio and river quality are the condition of rainfall and runoff, the ratio of separate system, the pollutant discharging to river and the water quality target. Non-point source pollutants that flow into river with runoff are the most important factor to be studied. At present, Shenzhen sewerage system is mainly a combined system, which includes rainwater and sewage water. Non-point source pollution accounts less for annual total pollutant output, but non-point source pollution can＇t be ignored because of its outburst in short time.
