韶关市供水水库水质现状和富营养化评价

The Analysis of Water Quality Status and Assessment of Water Quality Eutrophication of 8 Water Supply Reservoirs in Shaoguan

本研究对广东省韶关市内8座饮用水水源地水库水质进行了分析,并采用富营养状态指数法对水库的富营养化状况进行了评价。结果表明,2013至2017年,8座水库水质总体保持较好,均处于Ⅱ类、Ⅲ类水质类别,主要污染指标为总氮、总磷、高锰酸盐指数;水库富营养状态处于贫营养或中营养。最后结合水库的实际情况,针对性地提出改善水库水质的建议和措施。

In this study, the water quality of 8 reservoirs which are the main drinking water sources was analyzed in Shaoguan City, Guangdong Province, and the water eutrophication of 8 reservoirs was evaluated comprehensively by using trophic status indices. The results showed that the overall water quality of 8 reservoirs have been maintained good level, which water quality categories have reached class II or class III during 2013 to 2017. The total nitrogen, total phosphorus and potassium permanganate index were the main pollution index. The nutrient status of the reservoirs is poor or medium nutrition. Finally, according to the actual situation of the reservoir, this study has put forward several suggestions and measures to improve water quality of raservoir. s：
