丰乐河徽州区段水质分析与评价

Analysis and Evaluation of Water Quality in Huizhou Section of Fengle River

以丰乐河(徽州区段)为研究对象,选择总磷、总氮、氨氮、化学需氧量、溶解氧、pH、透明度等七个指标,利用污染指数法对10个代表性段面进行水质评价。结果表明,丰乐河(徽州区段)10个断面均达到了地表水Ⅲ类水标准,水质较好,水体整体处于尚清洁水平。下游的两个检测点位存在潜在的有机物超标风险,应加强管控。

Taking Fengle River(Huizhou Section) as the research object, seven indicators including total phosphorus, total nitrogen, ammonia nitrogen, chemical oxygen demand, dissolved oxygen, pH and transparency were selected to evaluate the water quality of 10 representative sections by pollution index method. The results show that the 10 sections of Fengle River(Huizhou section) meet the class Ⅲ surface water standard, the water quality is good, and the water body is still in a clean level. There is a potential risk of exceeding the standard of organic matter in the two detection points of downstream, so the control should be strengthened in the future.
