Urban river water environment treatment method
The invention discloses an urban river water environment treatment method. Water in a riverway is isolated by using a water-stop wall and a soil-retaining pile along a riverbank retaining wall in theriverway to form a near-shore zone, and the near-shore zone has all functions of intercepting main pipes and collecting pollutants entering the riverway; the near-shore zone is divided into an ecological shallow water area and a local deep water area. River sludge and biological filler are filled in the ecological shallow water area, and aquatic plants are planted on the biological filler layer, so that all functions of purifying water quality, beautifying landscape and the like of the ecological floating island can be realized; the local deep water area is arranged at a river inlet, filled with river silt and covered with a biological filler, and the water bottom elevation is lower than that of the river inlet; sewage lifting pumps are arranged in the near-shore zone at fixed points, andvarious kinds of sewage in the near-shore zone are collected in a centralized mode and discharged into a municipal sewage system or enter an independent water treatment device. The method is convenient to construct, low in engineering investment, short in construction period and low in operation and maintenance cost, can effectively collect and treat pollutants entering the river, and has popularization and application prospects in the aspect of river water environment treatment.
本发明公开了一种城市河道水环境治理方法。在河道内沿河岸挡墙用隔水墙和保土桩隔离河道内水体，形成近岸带，具有截流干管收集入河污染物的全部功能；近岸带内分为生态浅水区和局部深水区；其中生态浅水区内填充河道淤泥和生物填料，生物填料层上种植水生植物，可实现生态浮岛净化水质和美化景观等全部功能；局部深水区设置在入河排口处，填充河道淤泥，铺盖生物填料，水底高程低于入河排口；在近岸带内定点设置污水提升泵，集中收集近岸带内的各类污水，排入市政污水系统或进入独立水处理装置。本发明施工方便，工程投资小，建设工期短，运维成本低，能有效对入河污染物进行收集处理，在河道水环境治理方面具有推广应用前景。
