摘要
合理设置断面于2010年11月至2011年3月每月采样1次对江安河武侯区段的一些常规污染指标进行了监测,并结合单因子污染指数法对各断面水质进行了评价,然后结合评价结果进行了分析。结果表明,以地表水环境质量标准中Ⅲ类标准计算得到的硫化物、TP、CODCr等指标的污染指数均已超过1,尤其是硫化物污染指数甚至达到99.60,表明江安河武侯区段水体已经受到严重污染,上游带来的污染是该段水体污染的主要原因。
Some routine pollution indexes of water quality in Wuhou interval of Jiang＇an river was monitored at several sections;and the water quality was assessed by single factor contaminant index method.After that,the reason of pollution in this interval was analyzed.The results showed that the contaminant index（based on rank Ⅲ of water quality stand） of CODCr,sulfides and total phosphorus（TP） were more than 1,especially that of sulfides reached up to 99.60,which showed that this interval was polluted,and the pollutant was mainly brought by water from up-flow.
