Research progresson mass transfer in biofilms for wastewater treatment
污水生物处理中生物膜传质特性的研究进展

Abstract: The biofim attached on the carrier surface, plays an important role in biofilm wastewater treatment processes. So revealing the mass transfer properties in the biofilm is helpful for improving the biofilm treatment performance and exploring the pollutants removal mechanism. A review about the research progress on mass transfer in biofilm was made from different angles, such as biofilm structure models, mass transfer micro-environment, mass transfer characteristics based on gas-liquid-solid three phases system, as well as mass transfer impact factors including biofilm structure and hydraulic conditions etc. Besides, some future research prospect have been summarized.
