宁夏沙湖水质净化综合治理工程实施效果分析

Analysis of the Implementation Effect of Ningxia Sand Lake Water Purifi cation Comprehensive Treatment Project

为消减湖区底泥对水体的污染,降低水体营养状态水平,提升水质,2018年宁夏沙湖实施了底泥清淤水质净化综合治理工程,针对重点区域实施排水清淤和水质监测,结果表明,水体主要污染物浓度均有不同程度降低,水质指标明显好转。底泥清淤水质净化综合治理取得了良好效果,可为后期湖泊水环境治理提供参考。

To reduce the lake district sediment to water pollution,reduce the level of water nutrition,improve water quality,in 2018 Ningxia sand lakes implemented the sediment dredging water purification comprehensive treatment project,focusing on the implementation of drainage dredging and water quality monitoring,shows that the main pollutant concentration has different degrees,water quality index change is improved signifi cantly.The comprehensive treatment of sediment dredging and water purifi cation has achieved good results,which can provide reference for the lake water environment treatment in the later stage.
