沈阳辉山水库流域环境污染现状调查及综合整治

Investigation on Present Environmental Pollution in Huishan Reservoir Region of Shenyang and Countermeasures

对沈阳辉山水库流域工业、生活、农业及地面径流污染源进行了详细调查,监测和分析了水质和底泥质量,并有针对性地探讨了生态整治方案.结果显示:辉山水库流域主要污染源为生活源和农业源,每年入库污染量约为CODcr 400吨、总氮6 200吨、总磷700吨、污水120万吨、粪尿4700吨、固废200吨;水库流域水质类别为劣Ⅴ类,为重度污染,水库重度富营养化;底泥受到不同程度富营养化污染,并且辉山明渠起点采样点重金属总铅含量不合格;生态整治方案能改善辉山水库流域环境质量,实现生态流域和景观流域完美结合.

In order to solve the problems of environmental pollution for Huishan reservoir basin of Shenyang that is important ecotypic everglade resource of water,the integrated investigation is progressed on sources of industrial,living,farming and surface runoff pollution.Water and river sediment quality is inspected and analyzed,and the ecological integrated regulation schemes are discussed as to the problems accordingly.The research results are as follows：the pollution of Huishan reservoir basin is mainly from living sources and farming sources.CODcr 400 tons,TN 6200 tons,and TP 700 tons are discharged into Huishan Reservoir basin every year.And the amount of wastewater can be up to about 120 million tons annually,of which manure and solid waste are 4700 tons and 200 tons respectively.The water quality all reaches inferior standard V which belongs to the severe pollution,while Huishan reservoir belongs to severe eutrophication. Moreover,analysis results indicate that river sediment is polluted with eutrophication of different degree and the amount of total lead sample from Huishan open channel does not meet the national standards.The ecological integrated regulation scheme can not only improve the environmental quality,but combine ecology with sight in Huishan reservoir basin.
