| 摘 要： | 正确认识和评价滴水湖水质的变化特征是进行水环境管理的前提。通过监测2006-2009年滴水湖水体溶解氧(DO)、高锰酸盐指数(CODMn)、五日生化需氧量(BOD5)、氨氮(NH3-N)以及总磷(TP)等5种主要污染因子的月度变化,利用综合水质污染指数法进行了比较评价。结果表明2006-2009年间滴水湖湖区整体水质已达到地表水IV类水标准(GB 3838—2002),水质状况有明显好转;有机污染物和总磷是滴水湖水体主要污染因子。

| Abstract: | Correct understanding and evaluating the change of water quality in the Dishuihu Lake have great significance for pollution control.Based on monitoring the monthly changes of DO,CODMn,BOD5,NH3-N and TP in 2006-2009,comprehensive water quality index method was used to evaluate the water quality in Dishuihu Lake.The results show Dishuihu Lake’s surface water quality in 2006-2009 meets GB 3838—2002 Standard Class IV,water quality is significantly improved and organic pollutants and TP are main pollution factors in Dishuihu Lake. |
