涴米河水质状况调查和富营养化评价

Water Quality Analysis and Eutrophication Evaluation of Yuanmi River

摘要: 针对松滋涴米河市区段水质调查实验，采用单因子指数和综合营养指数法对涴米河水质状况和富营养化程度进行分析。结果表明，除氨氮未超标外，涴米河各监测点的TN、TP和CODMn超标明显，其中CODMn单因子指数基本满足IV水质标准，TN和TP单因子指数基本满足V类水质标准；从富营养化评价结果来看，涴米河水体已呈现中度富营养化。涴米河纵贯涴市镇，其水质状况关系到当地居民的生活和经济的发展，需相关部门进行综合整治。

Abstract: The water quality and eutrophication degree of Yuanmi River were analyzed by using single factor index and comprehensive nutrition index. The results showed that except NH₃-N, TN, TP and CODMn in each monitoring point of Sumi River exceeded the standard obviously, among which CODMn single factor index basically met the IV water quality standard, TN and TP single factor index basically met the V water quality standard. According to the eutrophication evaluation results, the Yuanmi River has been moderately eutrophicated. Wumi river runs through Yuanshi Town, and its water quality is related to the life and economic development of local residents, which needs comprehensive treatment by local government.
