入库径流污染综合防控技术应用实践——以彭州市西河水库为例

Application Practice of Reservoir Runoff Pollution Control and Prevention Technology——A Case Study of Xihe Reservoir in Pengzhou

针对彭州市西河水库污染现状及污染来源特征,为有效限制和处理入库径流污染物,结合库区自然条件,集成了"生态护坡—岸边人工湿地—人工浮岛"综合防控技术,并设计建设了示范工程。工程运行监测结果表明:经示范工程处理过的径流来水,除总氮以外,其他指标可以达到地表水Ⅲ类标准要求,其中,来水总氮平均超标63%,出水总氮平均超标24%,工程平均削减总氮23.93%。"生态护坡—岸边人工湿地—人工浮岛"综合防控技术及示范工程在西河水库径流污染防控方面发挥了积极作用,可以为类似水源污染防控提供技术参考。

Based on the pollution status and character of Xihe reservoir,the study designed ＂ecological slope protectionartificial wetland-artificial floating islands＂ pollution prevention technique and built demonstration project to solve reservoir runoff pollution problem.The demonstration project operation results showed that the ＂ecological slope protection-artificial wetlandartificial floating islands＂ pollution prevention technique was an effective measure to control Xihe reservoir runoff pollution.Indexes could all reach surface water Ⅲ standard except for total N.The average total nitrogen of inflow and outflow water were 63％ and 24％ higher than the standard respectively.The removal rate of total nitrogen was 23.93％.The results showed that the pollution prevention technique and the corresponding demonstration project were effective to control runoff pollution.The research results also could provide technical reference for similar water source pollution prevention.
