Membrane fouling and micro-pollutant removal of membrane bioreactor treating landfill leachate

摘要

The characteristics of landfill leachate from solid waste disposal vary, depending on waste composition, waste age, and landfilling technique. Landfill leachate also contains a wide range of pollutants of varying concentrations, from high for organic matters, nutrients, and inorganics to low for toxic micro-pollutants. Membrane bioreactor (MBR) technology has been increasingly adopted to treating landfill leachate. However, membrane fouling and micro-pollutant removal mechanisms of MBR and their relationship are little publicized. This paper thus aims to review publications related to these topics in the previous 5 years. Future development in MBR technology for improved landfill leachate treatment is also elaborated.
