【摘要】 用实验考察了城市生活垃圾中含有煤灰渣这一情况下堆肥的可能性 ,重点分析了煤灰渣的含量对堆肥过程的影响。同时 ,初步确立了此种情况下的较优工艺条件为 :含水率 5 0 %～ 60 % ,有机质 4 0 %～ 60 % (w/w干物料 ) ,煤灰渣 4 0 %～ 60 % (w/w干物料 ) ,C/N比 2 5∶1～ 35∶1,通风量 0 0 5～ 0 2 0m3/min·m3堆层 。更多还原

【Abstract】 Considering the fact that there are some coal ashes in the refuse in some cities of north China, the author studied the feasibility of composting in this situation and the effect of the concentration of coal ash on the process of compost. The values of moisture,total organic matter,concentration of coal ash,C/N ratio and aeration were suggested to be 50%～60%, 40%～60% ( w/w Dry weight ),40%～60%( w/w Dry weight),25∶1～35∶1and 0.05～0.20m3/min·m3, respectively.更多还原
