摘要 以京杭运河镇江丹徒段辛丰镇、王家桥断面为研究对象,通过对断面所在区域的水环境状况评价和区域污染源特征分析,确定超标污染物因子氨氮、总氮主要污染来源于农业生活源,并识别得到造成水污染的几大主要问题。同时,通过水环境容量的计算和分配,与运河该段的排污量对比,得到现状污染源排放量的需削减量和整治方案,实现断面水质达标,为地方环保管理部门提供了技术支撑,有利于京杭运河水环境的根本化改善。 Taking Xinfeng Town and Wangjiaqiao section of Zhenjiang Dantu section of the Beijing-Hangzhou Grand Canal as the research object,through the evaluation of water environment and the analysis of the characteristics of regional pollution sources,it is determined that the main pollution sources of ammonia nitrogen and total nitrogen are agricultural sources,and several major problems causing water pollution are identified. In addition,through calculation and distribution of water environmental capacity,compared with the discharge volume of this section of the canal,we can get the reduction and treatment plan of the current pollution source emission,and achieve the water quality standard of the section,and provide technical support for the local environmental protection management department,which is conducive to the fundamental improvement of the water environment of the Beijing-Hangzhou Grand Canal.
