Characteristics of Bioreactor Landfill Technology and Its Future Application

The disadvantages of conventional Sanitary Landfill(CL) were analyzed, and the structural characteristics of Bioreactor Landfill(BL) were described, and the biodegrading characteristics of BL technology was introduced by taking a BL research project conducted in California as an example. The preliminary experimental results showed that the biodegradation capability of BL was strongly enhanced due to the leachate recirculation and moisture content adjustment. As compared with CL, BL could increase 75% landfill gas amount and approximately 4 fold landfill volume reduction, and faster leachate stabilization. Finally, the current status of refuse treatment technologies in China was analyzed, and the potential application of BL technology in China was investigated as well.
