吐曼河水质状况及污染趋势分析

On Water Quality and Pollution Trend of Tuman River

该文利用2010年各月份吐曼河流域3个断面的水质监测资料,对吐曼河主要污染指标即石油类、NH4-N、COD、总磷等四个项进行分析。结果显示:(1)吐曼河水质存在一定的季节变化规律,整体呈现春冬季枯水期水质相对较差,夏季丰水期水质相对较好的变化趋势。(2)吐曼河主要超标污染物石油类、NH4-N的浓度自上游断面至下游断面逐步升高。(3)通过对吐曼河水质状况的综合分析,总结出污染变化趋势,并提出初步对策。

In this paper, the contamination index of Tuman River, such as petroleum, NH4 -N, COD and total phosphorus, is analyzed on the basis of the monthly motoring data of water quality from 3 sections in 2010, itshows that, 1 ） the water quality there has seasonal variation, good in summer but somewhat poor in winter; 2） the pollutants that exceed standards are petroleum and NH4 - N, escalating from upstream to downstream. Thevariation tendency of pollution is found out, and the countermeasures are put forward after comprehensive analysis of the water quality of this river.
