摘要
采用河流监测断面主要水质监测指标溶解氧、高锰酸盐指数、五日生化需氧量、化学需氧量、氨氮、总磷的年均浓度监测值,计算了污染物浓度超标指数。通过计算结果将6个辖区的水污染物浓度归入超标、接近超标和未超标三种类型之一,最后根据水环境承载能力分析结果,提出了从环保设施建设、源头污染治理、河道综合整治等方面开展流域水污染物削减的对策建议,以期促进流域内水质持续改善。
The annual average value of dissolved oxygen,permanganate index and biochemical oxygen demand after five days chemical oxygen demand,ammonia-nitrogen and total phosphorus in water quality monitoring sections is analyzed.Then water quality monitoring index is calculated.Through the calculation results,the concentration of water pollutants in the six jurisdictions is classified into one of three types:exceeding the standard,close to exceeding the standard and not exceeding the standard.At last,based on evaluation results of water environment carrying capacity,this paper puts forward the reduction of water pollution from the construction of environmental protection facilities,source pollution control and comprehensive improvement of river courses,in order to promote the continuous improvement of water quality in river basin.
