摘要：

在曝气池中种植芦苇,将普通的膜生物反应器(MBR)改造成生态式膜生物反应器(EMBR)。采用EMBR处理生活污水,对其处理效能进行中试研究。试验结果表明,EMBR能够有效去除有机物及营养物质,对COD、BOD₅、NH₃-N、TN、TP的平均去除率分别为95.7%、97.3%、97.3%、48.7%、79.3%。EMBR处理效能的提高主要归功于芦苇根系附着生物膜的生物降解作用以及芦苇的吸收作用。

Abstract:

Reeds is planted in an aeration tank. Then,the ordinary membrane bioreactor(MBR) is reformed to an ecological membrane reactor(EMBR). The EMBR can be used for treating domestic sewage. The pilot scale study on its treatment efficiency has been accomplished. The experimental results show that the EMBR can remove the organic substances and nutrients effectively,the average removing rates of COD,BOD₅,NH₃-N,TN and TP are 95.7%,97.3%,97.3%,48.7% and 79.3% respectively. The improvement of EMBR treatment efficiency mainly owes to the adhering biofilm biodegradation of the reed roots,as well as the adsorption of reed roots.

Key words: membrane bioreactor, reeds, domestic sewage
