摘要
开展水源地水库的污染来源解析,掌握影响水质的主要污染源,是改善水库水环境和保障饮用水源安全的基础。目前,国内关于水源地水环境污染物源解析的研究相对较少。本文以南方某水库为例开展水库污染来源解析,探索水库污染来源解析方法。研究结果表明,南方某水库NH3-N、TN、TP主要污染来源是外来引水,贡献占比高达81.9%、95.7%和92%,入库支流、散流入库、大气沉降、底泥释放污染负荷贡献均较小。
Analyzing the sources of pollution in reservoir and mastering the main pollution sources that affect water quality, is the basis for improving the reservoir water environment and ensuring the safety of drinking water sources. At present, there are relatively few studies on the source analysis of water environmental pollutants in water sources in China. This paper takes a reservoir in South-China as an example to analyze the source of reservoir pollution and explore the method of reservoir pollution source analysis. The results show that the main pollution sources of NH3-N, TN and TP in the reservoir are external water diversion, with a contribution ratio of 81.9%, 95.7% and 92%. Inflow tributaries, scattered inflows, atmospheric deposition, or sediment release pollution load contribution is small.
