摘　　要：为了考察在生活垃圾中添加具有吸附性和干燥性的填料对垃圾降解速率、渗滤液产生量、渗滤液水质的影响,在实验室建立了五个圆柱形垃圾厌氧填埋反应器,用于模拟垃圾填埋场的运行情况,以不添加填料反应器作对比,其余四个反应器中分别混合加入锯末、活性炭、沸石、报纸作为填料。实验中对五个反应器中的垃圾层高度、渗滤液产生量、产生渗滤液的COD和NH3-N及重金属离子浓度进行了检测。实验结果表明:在垃圾中添加具有吸附和干燥性的填料具有减少渗滤液产量、加速垃圾降解和减少溶入渗滤液中污染物质的作用,整体来看,锯末在发挥这些作用方面要好于其他三种填料。In order to study the effect of fillers with ability of adsorption and drying on rubbish degradation,leachate yield and water quality of leachate,five cylinder reactors for landfill disposal were built to simulate the operation of landfill.One reactor was used as contrast reactor with no filler added.Saw powder,activated carbon,zeolite and newspaper were added into the other four reactors.In the experiment,rubbish cell height,leachate amount,the concentration of COD,NH3-N and heavy metals in leachate were monitored.The results indicate that addition of fillers with ability of adsorption and drying in rubbish have strong effect on reducing leachate amount,accelerating degradation of rubbish and reducing pollutants in leachate.Overall,saw powder is better than the other three.
