摘　　要：研究了5年填埋龄准好氧和厌氧填埋体的沉降量、温度和填埋气产生特性,并分析了填埋处理陈腐垃圾的理化性质.结果表明:5年填埋龄准好氧填埋体的表面沉降量和减容率均显著高于厌氧填埋体,同时渗滤液回灌比清水回灌更容易引起垃圾填埋体表面的不均匀沉降.厌氧填埋体的平均温度(25.6℃)略高于准好氧填埋体(24.8℃),但差异不显著.准好氧填埋体不同时期的O2浓度分别高于厌氧填埋体,而CH4浓度则显著低于厌氧填埋体.5年填埋龄准好氧和厌氧填埋体陈垃圾中厨余物和纸类等易降解有机物含量显著降低,塑料、玻璃、砖瓦和竹木等含量则升高.其中,陈垃圾中有机质与营养元素含量均高于典型南方土壤;除厌氧填埋体陈垃圾中Cr含量超标外,其余重金属含量均未超出《土壤环境质量标准(GB15618—1995)》的三级标准要求.This paper studied the surface settlement, temperature, and gas production of land-filling pile, and the physical and chemical properties of aged refuse in 5-year-old semi-aerobic and anaerobic landfills. The pile’s surface settlement and its volume reduction rate were significantly higher in semi-aerobic than in anaerobic landfill; and the treatment with leachate recycling brought larger uneven settlement than the treatment with water recycling. The temperature of anaerobic landfill pile （25.6 ℃） was slightly higher than that of semi-aerobic landfill file （24.8 ℃）, but the difference was not significant. During land-filling period, the O2 concentration in semi-aerobic landfill pile was significantly higher than that in anaerobic one, while the CH4 concentration was in reverse. After 5 years land-filling, the contents of easily degradable organic matters in aged refuse, such as kitchen refuses and papers, decreased dramatically, while the contents of plastics, glasses, bricks, and woods increased. In addition, the contents of organic matters and nutrients in aged refuse were higher than those in typical southern China soils, and the concentrations of heavy metals except chromium in anaerobic landfill aged refuse were not beyond the grade three of Environmental Quality Standards for Soils （GB 15618-1995）.
