摘要
通过对于桥水库水源地的污染现状和外源污染源的分析,得出农田径流和畜禽养殖是水库周边面源氮磷污染负荷的主要来源。水库流域范围内分布的大量选矿厂是入库河流水体中铁超标的主要原因。另外,于桥水库周边农村生活污水排放也对水库水质构成了威胁。针对于桥水库水源地外源污染问题提出了外源污染控制和环境保护对策。
Based on the analysis of pollution situation and external pollution source at the water source of Yuqiao Reservoir,the paper pointed out that the farmland runoff and livestock breeding were the major source of non-point TN and TP pollution surrounding the reservoir.The numerous mineral processing plants in the reservoir watershed were response for the excessive levels of total Fe in the river water.In addition , the discharging of rural domestic sewage from the surrounding villages also posed environmental threaten to the water quality of the reservoir.To aim at external pollution of the Yuqiao Reservoir,the paper put for-ward measures on external pollution controlling and environmental protection.
