摘 要:利用2001—2015年松花江流域国家监测网30个可比断面监测数据,从流域和断面水质变化、各项指标超标情况和浓度变化、污染负荷等方面分析了松花江流域水质变化情况。结果表明,松花江流域水质总体呈好转趋势,特别是2007年以来有比较明显的改善。该流域长期以来主要污染指标为高锰酸盐指数、石油类、五日生化需氧量和氨氮。高锰酸盐指数、石油类和五日生化需氧量污染均有明显改善,但氨氮污染改善不明显。在继续加强COD排放总量控制的基础上,有效削减氨氮排放是促进松花江水质改善的重点。Using the national monitoring network's monitoring data from 30 comparable sections of Songhua River basin in 2001—2015,local water quality change situation was analyzed from the aspects of the basin and section,water quality change,the exceeding standard and concentration change of indicators,pollution load. The results showed that: Songhua River showed an improving trend of its overall water quality,especially an obvious improvement since 2007. The main pollution indicators in Songhua River basin were COD_(Mn),petroleum,BOD5 and NH_3-N for a long time. The pollution of CODMn,petroleum and BOD_5 showed a significant improvement trend. NH_3-N pollution improvement was not obvious. Basing on strengthening the total COD emission control,effectively cutting the NH_3-N emissions should become the focus for improving the water quality of Songhua River.
