污水生物处理中生物膜传质特性的研究进展

摘要

生物膜法处理污水,起主要作用的是附着于填料表面形成的生物膜,因此研究生物膜的传质特性对于提高处理效率、探究处理机理具有重要意义.本文综述了生物膜传质特性在污水生物处理中的研究进展,包括生物膜结构模型、传质微环境,以三相传质体系为研究重点的传质特性,以及影响生物膜传质的因素包括生物膜结构和水力条件等,并对以后应着重开展的研究进行了展望.

The biofim attached to the carrier surface plays an important role in wastewater treatment processes.So revealing the mass transfer properties in the biofilm is helpful to improve the biofilm treatment performance and explore the pollutant removal mechanisms.A review of the research progress on mass transfer in biofilms was made from different aspects,such as structure models,the mass transfer micro-environment,mass transfer characteristics based on a gas-liquid-solid three phase system,as well as mass tran...
