摘　　要：地下水面源污染具有很强的不确定性、复杂性及广泛性,使地下水面源污染难以控制,因此研究了一种城乡规划地下水面源污染负荷控制方法。该研究中利用相应的装置及设备监测降雨径流情况,获取地表径流数据及污染参数。计算面源污染负荷数值,并结合研究区基础空间和属性数据,划分面源污染路径。接着在路径上设置拦截过滤装置,再集水到人工湿地区,增强对污染的净化力度。结果表明:利用该方法控制地下水面源污染,COD_(cr)、BOD_(5)、总氮和总磷四个指标数值都有了很大程度的降低,说明该方法具有很好的污染净化效果,达到了研究目标。Groundwater non-point source pollution has strong uncertainty,complexity and universality,which makes it difficult to control groundwater non-point source pollution.Therefore,a control method of groundwater non-point source pollution load in urban and rural planning is studied.In this study,corresponding devices and equipment are used to monitor rainfall runoff and obtain surface runoff data and pollution parameters.The study calculates the value of non-point source pollution load,and divides the non-point source pollution path by combining the basic space and attribute data of the study area.It then sets up intercepting and filtering devices on the path,and collects water to the artificial wet area to enhance the purification of pollution.The results show that the four index values of COD_(cr),BOD_5,total nitrogen and total phosphorus have been greatly reduced by using this method to control groundwater non-point source pollution,which shows that this method has good pollution purification effect and reaches the research goal.
