摘要
针对污水处理厂尾水湿地中常存在的碳源不足、氮去除率较低问题,研发了自供碳尾水湿地构建技术体系,该技术体系包含构建湿地植物供碳周年模式、不同物候型水生植物配置效果评价、构建复合人工湿地处理系统和关键过程的参数化。技术体系已成功应用于大型尾水湿地工程示范,可广泛应用于尾水湿地构建工程。
Aiming at the problems of insufficient carbon source and low nitrogen removal rate in the tailwater wetland of sewage treatment plant,a technical system for the construction of self-supplied carbon tailwater wetland was developed,which included the construction of annual carbon supply mode of wetland plants,the evaluation of the allocation effect of different phenological aquatic plants,the construction of composite constructed wetland treatment system and the parameterization of key processes. The technical system had been successfully applied to the demonstration of large-scale tailwater wetland projects and could be widely used in tailwater wetland construction projects.
