膜生物反应器工艺应用争议问题分析及改进建议

Analysis of the main controversy and improvements in the application of MBR technology

由于膜生物反应器(MBR)是一种相对较新的技术,随着项目数量和处理规模不断增加,其在应用过程中出现了许多有争议的问题。分析了产水量下降、耐水量冲击负荷能力差、存在技术壁垒等技术方面和投资费用较高、能耗高、运行成本较高等经济方面存在的一些主要的争议问题,并提出了相应的改进措施与建议,以期为MBR工艺的规模化设计应用提供参考。

By the increasing of the scales and numbers of membrane bioreactor （MBR） plants,many controversies appeared in the application since MBR was a new technology in the sewage treatment plants. Some of the main technical and economic controversies such as the decline of flux, the weak ability against the larger amount of influent, technical barriers, higher investment, higher energy consumption, higher running cost and so on, were analyzed in this paper. And some improvements were put forward in order to provide some references for the large-scale application of domestic MBR technology in the future.
