Degradation of Landfill Leachate by Ultrasound/Ultraviolet - Aged Refuse Bioreactor Combined Process

Abstract:

The biodegradability of aged landfill leachate is low, and the treatment effects of common processes are very poor. This paper explored the effects of the Ultrasound/Ultraviolet - Aged Refuse Bioreactor combined process on aged landfill leachate. The main results were as follows: 1The optimum power of ultrasound was 100 W, and the optimum wavelength of ultraviolet was 254 nm. The removal rate of COD was 27.33% and the value of BOD/COD ratio was increased from 0.1 to 0.35 after the treatment of Ultrasound/Ultraviolet process. Therefore, the biodegradability of the leachate was improved, which might meet the demand of subsequent biological treatment. 2The COD removal rates of the two-stage series aged refuse bioreactor were both kept above 50% during the experiment and this process had a strong capacity of resistance to impact load. 3The COD removal rate of the combined process was over 80% as a whole without any pretreatment, and it has positive significance for the treatment of aged leachate.
