摘要
青草沙水源地自投入运行以来,水质的质量,一直是人们迫切关心的问题。本文对上海市青草沙水源地地表水在2010年至2011年的水质状况进行了监测评价。选取了溶解氧、高锰酸盐指数、化学需氧量、五日生化需氧量、氨氮、挥发酚、石油类、总磷和总氮这九个地表水常用指标对青草沙水源地的地表水的水质状况进行了评价,研究结果表明,青草沙水源地在2010～2011年中有机综合污染指数和水质综合污染指数平均值分别为-0.2和0.8,能达到地表水Ⅱ类标准,总氮超过相应类别的标准,但其指标不直接影响到水体功能效应,水体功能没有受到明显损害,但在一定程度上受到总氮污染的制约。
Qingcaosha water resources received much attention since its working for the drinking water resources. The surface water quality of Qingcaosha water resources was researched during 2010 - 2011. Choosing dissolved oxygen, po- tassium permanganate index, chemical oxygen demand, five -day biochemical oxygen demand, ammonia nitrogen, vola- tile phenol, petroleum, total phosphorus and total nitrogen as the monitoring items, the water quality was assessed. The average value of organic pollution index and comprehensive pollution index for Qingcaosha water resources were - 0.2 and 0.8, reaching the sort I1 of environmental quality standard for surface water. The total nitrogen exceeded the correspond- ing standard, however, the item unimpacted the water function directly. The Qingcaosha＇ s water function didn＇t harm ob- viously, but it was restricted by the total nitrogen pollution.
