牡丹江水质状况分析研究

Analysis on Water Quality of Mudan River

对牡丹江2008—2010年水质状况分析结果表明,高锰酸盐指数和氨氮未达到功能区划标准,但是超标断面比例呈减少趋势,达标断面比例呈增加趋势。各断面生化需氧量、挥发酚、总氰化物、石油类都已达标,且呈逐年变好的趋势,经过牡丹江市区段,即江滨大桥—柴河铁路桥段,各项指标都有不同程度的升高。在牡丹江水质状况分析的基础上,提出了牡丹江水环境保护对策。

The water quality of Mudan River was analyzed from 2008 to 2010. The result showed that permanganate index and ammonia nitrogen did not reach standards of the functional zoning. However,there was a decreasing trend for the proportion of over standard section while an increasing trend for ones of reaching standard.Biochemical oxygen demand, volatile phenol, total cyanide petroleum came up to the standard requirements and they decreased year by year. Nevertheless ,all of them were raised through Mudanjiang city region that was from Jiangbin Bridge to Chaihe Bridge. At the meantime, strategies of water environment protection in Mudan River were proposed basing on water quality assay.
