沱江富顺段水质分析及污染状况研究

为了解沱江富顺段水质情况，采用相应的国家标准方法对沱江水体的氮、磷、化学需氧量、生化需氧量等指标进行监测。3个监测断面TN、TP的平均浓度分别为3．31mg／L、0．247mg／L，其中TN含量超标3倍以上，TP含量超过标准的1．2倍，建议相关部门应在河流平水期和枯水期严格控制氮、磷的排放，可通过调高工业废水、污水处理厂氮、磷排放标准，缓解沱江氮、磷污染程度。

Study of Water Quality Analysis and Pollution Status of Tuojiang River in the Area of Fushun

In order to know the water quality of Tuojiang River in Fushun areas, nitrogen, phosphorus, chemical oxygen demand, biochemical oxygen demand of the Tuojiang River are detected using national standard method. Results show that the average concentration of TN and TP are 3.31mg/L, 0. 247mg/L of the three monitoring sections, respectively. TN value exceeded the standard more than three times, the TP exceeded the standard 1.2 times. It is recommended that relevant departments should control nitrogen and phosphorus emissions at medium seasons and dry seasons strictly by raising nitrogen and phosphorus emissions standards of industrial waste water, sewage treatment plant to ease the Tuojiang nitrogen and phosphorus pollution.
