城市郊区小流域污染源调查及分析——以南京市江宁区团结河为例

Investigation and Analysis on Pollution Sources in Small Watersheds of City Suburbs——A Case Study of Tuanjie He of Jiangning District,Nanjing City

以南京市团结河为例,研究细化小流域污染源计算方法。将团结河流域的主要污染物排放量及入河量量化处理,分析流域主要污染物的来源及其构成,明确辨别流域内各片区及各类污染源的污染物贡献率,为特定目标下的流域污染物削减量计算奠定基础,使后续环境整治更有针对性和目标性。

By taking Tuanjie He of Nanjing city as an example, this paper studies the calculating method of the pollution sources in the small watersheds. The paper quantizes the major pollutant discharge amounts and river intakes, analyzes the sources and their compositions of the major pollutants in the watersheds. The paper identifes the contribution rates of pollutants in each area and various pollution sources in the watershed in order to lay a foundation for the calculation of the removal of pol-lutants in the river basin under a specifc target, so that subsequent environmental remediation shows its pertinence and target.
