摘　　要：通过现场调查和监测分析手段,对水库入库支流、外来引水及散流入库的氮磷污染负荷进行核算,旨在摸清其污染来源,并针对主要污染来源提出相应污染控制对策,为该市饮用水源地管理和饮用水安全保障提供技术支撑。结果表明,S水库NH3-N和TP污染负荷来源中本地源占比高达90%和81%,其中以支流R5贡献最大,分别贡献40%和21%;TN污染负荷来源中外来引水占比最高,为67%。一方面该市需要新建流域内污水管网,推进雨污分流,提高污水收集处理能力;另一方面需要协调推动引水水源保护工作,从而降低该水库供水风险,保障该市饮水安全。By field investigation and monitoring analysis,this paper calculates the nitrogen and phosphorus pollution load of different sources,such as the tributary water,channel water and the inflow of scattered water,in order to find out the source of pollution,and puts forward corresponding pollution control countermeasures,so as to provide technical support for the management of drinking water source and the safety guarantee of drinking water in this city.The results show that 90%and 81%of the sources of NH3-N and TP pollution load in S reservoir are from local sources,of which R5 is the largest contributor,accounting for 40%and 21%respectively;and 67%of TN pollution load is from external sources.On the one hand,the city needs to build a new sewage pipe network in the basin,promote rainwater and sewage diversion,to improve sewage collection and treatment capacity.On the other hand,it needs to coordinate and promote the protection of water sources for water diversion,so as to reduce the water supply risk of the reservoir and ensure the safety of drinking water in the city.
