人工湿地中装配式填料模块设计及应用

Design and Application of Prefabricated Filler Module in Constructed Wetland

人工湿地在长时间运行过程中一个难以解决的问题就是填料的堵塞,通常情况下采用反冲洗、停床轮休、曝气充氧的对策予以缓解,但不能实质性解决堵塞问题。本文提出填料模块化是解决问题的有效途径,即采用装配式模块装载填料,实现湿地堵塞后的填料模块快速更换,以恢复湿地功能;填料的模块化、产业化、可再生化将是未来人工湿地技术发展与推广的重要方向。

In the process of long-term operation of constructed wetland,one of the difficult problems to solve is the blockage of filler.In general,the Countermeasures of backwashing,bed stopping and aeration oxygenation are used to alleviate the problem,but the blocking problem can not be solved substantially.This paper puts forward that the filler modularization is an effective way to solve the problem,that is to use the prefabricated module to load the filler,to realize the rapid replacement of the filling module after the wetland blockage,so as to restore the wetland function.Modularization,industrialization and regeneration of fillers will be the important direction for the development and promotion of the constructed wetland technology in the future.
