摘　　要：为探究生态清淤耦合生态恢复技术措施对污染水体恢复的作用,选取水体水质指标总磷、总氮、化学需氧量为研究对象,依托白洋淀内源污染治理试点工程项目,针对目标鱼塘设置原位治理区、原状保留区、生态清淤耦合生态修复区3种工况,通过连续采样检测,获得了不同工况下的水质变化规律。研究结果表明:1)采用生态清淤和原位修复措施均可使水体总磷、总氮、化学需氧量提升至地表水Ⅴ类水标准,但水体水质难以达到地表水Ⅲ类水标准;2)相较于仅用单一的原位修复技术,生态清淤耦合生态恢复技术更具优势,一定时间后水体总磷、总氮、化学需氧量指标可达到地表水Ⅲ类水标准。To explore the effect of ecological dredging coupled with ecological restoration technology on the restoration of polluted water, water quality indexes named total phosphorus, total nitrogen and chemical oxygen demand are selected as the research objects. Relying on the Baiyangdian endogenous pollution control pilot project, three working conditions are set for the target fish ponds: in situ management area, original retention area and ecological desilting coupled ecological restoration area. Through continuous sampling and detection, the variation rules of water quality under different working conditions are obtained. The results show as follows: 1)The use of ecological dredging and in-situ restoration measures can promote the total phosphorus, total nitrogen, and chemical oxygen demand of the water to increase to the surface water Class V water standard, but the water quality is difficult to reach Class III water standard;2)Compared with only a single in-situ restoration technology, the ecological dredging coupled with ecological restoration technology has more advantages. After a certain period of time, the total phosphorus, total nitrogen and chemical oxygen demand indicators of the water will reach the surface water Class III.
