通过粉煤灰、炉渣和生活垃圾共置处理,研究粉煤灰、炉渣提高生物反应器垃圾处理性能的机理和效果。结果表明：粉煤灰、炉渣可以有效去除重金属离子,调节反应器内pH,使渗滤液停留时间延长4倍～5倍,产气量提高5.9倍～7.8倍,甲烷含量可提高2倍以上,共置处理效果显著好于生活垃圾单一处理。“,”This paper researched the mechanism and the effect of the bioreactor for treating refuses by adding fly ash and cinder.The results showed that the fly ash and cinder could obviously decrease the heavy metal concentration,adjust the pH,entend the penetration time of leachate by 4~5 times,increase the gas production by 5.9 to 7.8 times,and also raise the content of methane by over 2 times.The efficiency of the co-disposal is much higher than the single treatment of domestic refuses.
