抚河干流水质评价与成因分析

Water Quality Assessment and Analysis in the Main Stream of Fuhe River

本文依据抚河历年水质监测数据,采用单因子评价法和趋势检验法,分析研究抚河干流水质现状、变化趋势及污染源成因等。分析结果表明：抚河干流水质总体良好,多数河段和年份水质优于III类;但是随着经济快速发展,工业废水、农村居民生活污水、农业生产的非点源污染随降雨径流输入河流,导致抚河干流水资源质量有下降趋势,其中氨氮、高锰酸盐指数等呈上升趋势,应引起有关政府部门的高度重视。

Based on water quality monitoring data, the status of water quality in the main stream of Fuhe river was assessed by using single factorial evaluation and trend test method. The change tendency and effects on river pollutions were analyzed. Results show that Fuhe River＇s water quality is generally better than level III in most years. As the fast development of economy, the industrial waste water, rural residential living waste water and agricultural non-point sources pollution are entering into Fuhe River by means of rainfall and runoff, which makes the water quality deteriorate obviously. At the same time, the indexes of ammonia nitrogen and permanganate are rising. All of these should get attention of relevant government departments.
