Method for constructing tail water wetland of sewage treatment plant by utilizing river channel
The invention discloses a method for constructing a tail water wetland of a sewage treatment plant by utilizing a river channel, relates to the technical field of sewage treatment, and solves the technical problems that tail water of an existing sewage treatment plant cannot reach the standard and is discharged, a wetland process adopted for tail water treatment occupies a large area, and the ecological environment of the river channel is poor. A pretreatment area, a wetland treatment area and a stabilization area which are sequentially communicated are constructed at the position close to a sewage treatment plant; the tail water of the sewage plant is conveyed through a pipeline to pass through the pretreatment area and then flows to the wetland treatment area, and the wetland treatment area comprises a natural wetland, a surface flow wetland and a horizontal subsurface flow wetland; waste water is alternately purified through the natural wetland, the surface flow wetland and the horizontal subsurface flow wetland, and finally enters the natural wetland and the ecological pond in the stable area and then is discharged. Tail water treatment of a sewage treatment plant is combined with ecological restoration of a river channel, an ecological river bank is built by utilizing an existing river bank, pollutants of tail water are degraded by planting emergent aquatic plants, submerged plants and floating-leaved plants, and runoff pollution is purified.
本发明公开了利用河道构建污水处理厂尾水湿地的方法，涉及污水处理技术领域，解决现有污水处理厂尾水不能达标排放、尾水处理采用湿地工艺占地面积较大以及河道生态环境的技术问题，本发明在靠近污水处理厂的位置构建依次连通的预处理区、湿地处理区和稳定区；污水厂尾水通过管道输送经过预处理区后，流至湿地处理区，所述湿地处理区包括自然湿地、表面流湿地、水平潜流湿地；通过自然湿地、表面流湿地、水平潜流湿地交替净化废水，最后进入稳定区自然湿地、生态塘后出水。本发明将污水处理厂尾水处理与河道生态修复相结合，利用现有河岸修建生态河岸，通过种植挺水植物、沉水植物及浮叶植物对尾水的污染物进行降解，净化径流污染。
