嘉兴平原河网水质闸泵调控优化方案浅析

Analysis on Jiaxing plain river network water quality brake pump control optimization plan

平原河网水环境污染是国内平原河网的共性问题。在平原河网地区采取闸泵调控手段来加速河水的流动,增加水的更新速率,从而使水质在短期内有所改善。然而,针对引水实施条件对受纳河道水体水质的影响尚缺乏全面的分析和研究。本文以嘉兴城区6km2示范区域内的河道底泥沉积物和河水为研究对象,在实验室中模拟示范区水环境,对比分析不同条件下对受纳河道水体水质的影响,为引水工程的方案设计与实践提供理论参考。

Water environment pollution of plain river network is a common problem of plain river network in China. Brake pump control measures are adopted for accelerating river water flowing, and water updating rate is increased in the plain river network region, thereby improving water quality in short term. However, influence of water diversion implementation conditions on pollution river water quality is not analyzed and studied comprehensively. In the paper, river bottom sediment and river water in Jiaxing urban 6km^2 demonstration area are regarded as study objects. Water environment of demonstration area is simulated in the laboratory. Influence on pollution river water quality under different conditions is comparatively analyzed, thereby providing theoretical reference for designing and implementing water diversion projects.
