大沽河水质自动监控点位布设初探

摘要

Through analysis on perennial hydrological conditions of Dagu River Basin and distribution of artificial monitoring point, pollution sources, sewage treatment plant, water intake, drinking water source protection areas and water conservancy pro-jects, this paper determined automatic water monitoring points in seven sections on the upstream of Dagu River , Jiangjiazhuang, Hajiahui to Mawan, Xiaogu Riger, Yunxi River entrance, Taoyuan River entrance into Dagu River downstream, Luoyao River and south of Jiaolai River.In addition to main monitoring indexes, the monitoring points were distributed in the key monitoring section and serious polluted areas to monitor total nitrogen, total phosphorus and other heavy metal indexes.%通过对大沽河流域常年水文状况，现有国、省控人工监测点位设置情况，污染源分布、污水处理厂、取水口、饮用水源地保护区分布及水利工程建设情况的调查，确定在大沽河上游、江家庄、韩家汇到麻湾桥段、小沽河汇入口、云溪河桃源河汇入大沽河口下游，落药河和南胶莱河等7个断面充分利用跨河桥梁等构筑物构建水质自动监控站点。主要监测指标除常规指标以外，在重点监控断面和工业企业分布较多的污染较重河段，可增加总磷、总氮等特征指标和重金属监测项目。
