摘  要：
改善新立城水库水环境,确保长春市饮用水源安全,水库污染源与污染负荷的分析研究是基础。通过采用单项指数法对水库丰水期和融雪期水环境质量进行了评价发现,氨氮(NH3-N)和总磷(TP)是水库水质超标的主要污染物。水库氮磷负荷量化选用平均浓度法和水库水质模型法,入库总负荷融雪期NH3-N1 708.0 kg/d,TP 255.0 kg/d;丰水期NH3-N 324.7 kg/d,TP 336.8 kg/d。其中,库周融雪期点源负荷NH3-N30.5 kg/d,TP 8.3 kg/d;库周丰水期点源负荷NH3-N 46.3 kg/d,TP 47.8 kg/d;库周融雪期非点源负荷NH3-N 96.7 kg/d,TP为6.4 kg/d;库周丰水期非点源负荷NH3-N 36.5 kg/d,TP 59.2 kg/d。上游来水是新立城水库主要污染来源,库周非点源负荷明显。为保证饮用水源地水质安全,水库上游流域环境污染治理和库周污染源削减迫在眉睫。

摘  要：
The analysis and quantification of nitrogen and phosphorus pollution sources is the base before managing the Xinlicheng Reservoir. To master the pollution sources and loads helps to take measures for improving the water quality. NH3-N and TP were the key pollutants resulted in deterioration of water quality by water environmental quality assessment method. The pollutants were from upstream flow and surrounding drainage of the reservoir. The surrounding drainage pollution sources consisted of point and non-point sources. The loads from upstream flow and surrounding drainage were estimated by mean concentration method and reservoir water quality model. The daily fluxes of ammonia nitrogen and total phosphorus in the snow-melting period and wet season were 1 708. 0 kg,255. 0 kg,and324. 7 kg,336. 8 kg into the reservoir,respectively. The input point source loads per day in snowmelting period and wet season were 30. 5 kg NH3-N,8. 3 kg TP,and 46. 3 kg NH3-N,47. 8 kg TP,respectively. And the input non-point source loads per day in the snow-melting period and wet season were 96. 7 kg NH3-N,6. 4 kg TP,and 36. 5 kg NH3-N,59. 2 kg TP,respectively. The pollution loads from the upstream of the reservoir was the key source. It is imperative to control the upstream water pollution and to reduce the surrounding pollution sources for the safety of drinking water source.
