摘要
淡水河是东江的二级支流,途经深圳、惠州两市诸多快速发展地区,是我国南部地区极为重要的河流,也是两市人民的饮用水源之一。本文以2017年淡水河流域各监测断面监测数据为分析样本,从自然和人文环境等多个维度修正污染排放系数,核算各污染源排放贡献值。结果分析表明,该流域污染主要源自生活污染排放,河流主要超标物为氨氮,而且人群聚集较多的淡水街道和秋长街道污染物排放量最大。该系统方案为复杂多变的城镇区域河流污染源分析提供了一种参考性技术方法。
The Danshui River is a secondary tributary of the Dongjiang River,passing through many fast-developing areas in Shenzhen and Huizhou,which is not only an extremely important river in Southern China,but also one of the drinking water sources for the people of the two cities.Taking the monitoring data of various monitoring sections in the Danshui River Basin in 2017 as the analysis sample,this paper revises the pollution emission coefficient,and calculates the contribution value of each pollution source from multiple dimensions such as the natural and human environment.The analysis of the results show that the pollution in this watershed mainly comes from domestic pollution discharge,the main over-standard substance in the river is ammonia nitrogen,and the Danshui Street and Qiuchang Street where there are more crowds discharge the largest amount of pollutants.The system scheme provides a reference technical method for the analysis of river pollution sources in complex and changeable urban areas.
