- Title:
- Research on Circulating Bypass IVCW for Water Quality Improvement
- 摘要:
- 基于妫水河设计年份存在的生态流量不足、水体流动缓慢、水质功能不达标、水生态景观较差等实际问题,依托河道沿岸现状循环管线,构建旁路循环复合流潜流湿地。研究结果表明,该项目最佳循环流量为7×104 m3/d,需配套建设湿地占地总面积为22.6 hm2;“下向流池+上向流池”复合垂直流潜流湿地可有效解决水平潜流湿地易出现的“短路”问题,同时可为湿地微生物提供良好的厌氧/缺氧/好氧微生环境;湿地出水COD、TP、氨氮三项指标优于地表水Ⅲ类标准,同时对TN有一定的削减效果。
- Abstract:
- Based on the actual problems of insufficient ecological flow, slow water flow, substandard water quality and poor water ecological landscape in the design year of Guishui River, the circulating bypass integrated vertical-flow constructed wetland (IVCW) is constructed on the basis of current circulating pipelines along the river. The main result shows the optimal circulating flow of the project is 7×104 m3/d, and the total area of the constructed wetland is 22.6 hm2. The IVCW combined with “downward flow pool and upward flow pool” could effectively solve the problem of short circuit which is prone to occur in horizontal subsurface flow wetland, and it could provide a good anaerobic/anoxic/aerobic micro-environment for wetland microorganisms. The effluent COD, TP and ammonia nitrogen of the wetland are superior to level Ⅲ criteria of Environmental Quality Standards for Surface Water (GB 3838-2002), and it has a certain removal effect on TN.
