Application of UASB Reactor in Leachate Treatment of Beijing Asuwei Waste Sanitary Landfill Site.

The UASB reactor was used to reconstruct leachate treatment project of Beijing Asuwei Waste Sanitary Landfill Site, and the commissioning with the UASB reactor was executed. Water quality indicators were determined in the debugging process, and the results showed that the VFA content in the anaerobic tank was controlled within 600 mg/L, which indicated that the water quality did not have the acidified phenomenon. The COD removal efficiency was 50% approximately and NH₃-N concentration showed as light decline when operation stability in anaerobic system. [ABSTRACT FROM AUTHOR]
