适当的水力条件是实现人工湿地处理目标和正常运行的基本保证。人工湿地水力停留时间较长是最为突出的一个问题,它直接导致了系统处理能力偏小。针对这个问题,本文采用改良型装配式人工湿地,进行了停留时间的试验研究。结果表明,在停留时间为4 d的条件下,COD的平均去除率为87.54%,NH4＋-N的平均去除率为37.08%,TN的平均去除率为31.9%。

The appropriate hydraulic condition is the basic guarantee of achieving treatment goals and normal operation of constructed wetland.The long hydraulic retention time is the most outstanding problem which directly leads to small processing capacity of the system.To solve this problem,this paper adopts the modified type of fabricated constructed wetland and studies the retention time.The results showed that the average removal rate for COD is 87.54%,for NH＋4-N 37.08%,and TN 31.9% in the condition of residence time of 4 days.
