摘要
利用水质指数法对滦河锡林郭勒盟段水质状况进行了分析评价,结果显示:(1)滦河锡林郭勒段2005-2007年主要污染因子为:高锰酸盐指数、化学需氧量、铁、生物需氧量、锰、总磷等;(2)2005-2007年间,上都河监测断面水质状况整体呈变好趋势,但地方经济增长带来的化学需氧量异常升高不容忽视,大河口断面不同水期水质状况变化不同;(3)2005-2007年,滦河锡林郭勒段化学需氧量与溶解氧超标污染加重明显、高锰酸盐指数超标污染逐渐减轻;三年内,上游水质均优于下游水质,两个监测断面水质均为丰水期水质<平水期水质<枯水期水质。
The water quality situation of Xi Lin Col Section of Luan river is analyzed and evaluated with water quality exponent method. The main pollution factors of Xi Lin Gol Section of Luan river from 2005 to 2007 are identified. The water quality situation of Shang Du river monitoring section is generally good, but COD is unusually increasing as local economy is growing a lot. The excess pollution of COD and DO are obviously exacerbated, and excess pollution of pcrmanganatc appears light.
