摘　　要：通过模拟试验,对卫生填埋(sanitary landfill)和生物反应器填埋(bioreactor landfill)处理城市生活垃圾进行了对比分析,着重研究了添加粉煤灰和炉渣对生物反应器填埋处理效果的影响。结果表明:与SL相比,BL的填埋气产量最高提高4.7倍,甲烷含量提高50%,渗滤液中COD值降低18%;添加粉煤灰和炉渣的生物反应器(BL2、BL3),相对于城市生活垃圾单一处置方式(BL1),填埋气总产量可提高7.8和5.9倍,日产气量提高10倍,甲烷含量可达58.7%,渗滤液中COD值降低60%,体积分数减少量11.7%,添加粉煤灰和炉渣对提高生物反应器填埋处理效果有着十分突出的作用。This paper compared the SL and BL for disposal of domestic refuses by simulative experiment,especially focused on the effect of BL with added the coal fly ash and slag.The results showed that the production of LFG in BL1 was increased by 4.7 times as compared with SL,the concentration of methane was improved by 50%,the COD of leachate was reduced by 18%;especially,compared with the BL1,LFG of BL2 and BL3 added coal fly ash and coal slag was increased by 7.8 and 5.9 times,LFG/d was increased by 10 times,and the concentration of methane reached the 58.7%,the COD of leachate was reduced by 60%,volume was reduced by 11.7%,it's significant to improved the effect of the BL.
