大治河有机污染源分析及防治对策

Analysis and Harness Countermeasure of Organic Pollution in Dazhi River

根据历年来大治河水质监测资料,分析了大治河水污染的特征是有机污染型。通过对大治河水源保护区域内的污染源调查,结果表明,有机污染中既有点污染源的贡献,但主要来源于非点污染源。后者的污染负荷是前者的54倍。因而提出了为改善和提高大治河水质的若干对策意见。

According to long-term monitoring data of Dazhi River, it was known that the characteristics of water pollution in this river is organic in origin. Through the investigation of pollution sources in the water resource protection zone, the result showed that the organic pol. lution involved both point sources and non-point source and mostly non-point source, the pollution load of NPS was about.50 fold of point sources. The countermeasure of ameliorating water quality were also recommended.
