Comparison between controlled landfill reactor and conditioned landfill bioreactor
Abstract： Bioreactor landfills allow a more active landfill management that recognizes the biological, chemical and physical processes involved in a landfill environment. The results of laboratory-scale simulators of landfill reactors treating municipal solid wastes were studied, the effect of solid waste size, leachate recirculation, nutrient balance, pH value, moisture content and temperature on the rate of municipal solid waste(MSW) biodegradation were determined, and it indicated the optimum pH value, moisture content and temperature can used to decompose MSW. The results of waste biodegradation were compared with that of the simulators of the leachate-recirculated landfill and conservative sanitary landfill. In the control experiment the antitheses of a decreasing trend of the organic load, measured as biological oxygen demand and chemical oxygen demand, was shown, and heavy metals concentration was observed. An obvious enhancement of effective disposal from simulator of conservative sanitary landfill(CSL), to that of leachate-recirculated landfill(LRL) and to that of conditioned bioreactor landfill(CBL) would be noted, through displaying the compared results of solid waste settlement, heavy metal concentration in leachate, methane production rate, biogas composition, BOD and COD as well as their ratio. 作 者： LUO Feng CHEN Wan-zhi SONG Fu-zhong LI Xiao-peng ZHANG Guo-qing 作者單位： LUO Feng,SONG Fu-zhong,LI Xiao-peng(College of Resource and Environmental Science,Chongqing University,Chongqing 400044,China)CHEN Wan-zhi(College of Resource and Environmental Science,Chongqing University,Chongqing 400044,China;Chongqing Environmental Protection Bureau,Chongqing 400010,China)
