近十年水磨河水质变化特征研究

利用水磨河2001—2010年各断面实测资料,采用单因子法和综合污染指数法分析了近十年该流域各断面主要污染物超标情况,沿程变化特征及年际、季节变化趋势。结果表明,搪瓷厂泉断面、七纺桥断面水质有所好转,下游联丰桥断面、米泉桥断面污染程度逐渐加重,超标污染项目逐年增加。高锰酸盐指数、氨氮、总磷浓度值在联丰桥断面直线上升,石...

Study on Water Quality Changes Characteristics Shuimo River in Recent Decades

Using the measured data of each section of the Shiumo River 2001 — 2010,using single-factor method and the integrated pollution index analysis of each section for nearly a decade of major pollutants exceeded the standard,the characteristics and inter-annual,seasonal variation trends.The results showed that the Tangcichang section,Qifang bridge section has improved water quality,Lianfeng bridge section,Miquan bridge section,the downstream pollution degree was gradually increased,excessive pollution projects was increasing year by year.Permanganate index,ammonia nitrogen,total phosphorus concentration straight up in Lianfeng bridge section,oil concentration did not change much,concentration from upstream to downstream was slowly increased.
