摘　　要：该文以上海老港填埋场55#单元的矿化污泥填埋区和固化污泥填埋区中分别经矿化垃圾和固化剂改性的填埋污泥为研究对象,对填埋过程中污泥的含水率、有机物含量、渗沥液成分和产气量的变化进行了分析。结果表明矿化垃圾和固化剂的添加可以加快填埋初期污泥的降解,且矿化垃圾的促进稳定效果更好;改性剂的添加可以明显缩短渗沥液有机污染物浓度达到峰值的时间;添加矿化垃圾可以为填埋污泥创造更好的产甲烷环境。The moisture content, organic compounds content, leachate composition and gas production of modified sludge blended with aged urban solid waste and sohdifying agents in Shanghai Laogang Landfill Site. Result shows that the addition of aged urban solid waste and solidifying agents can speed up the primary decomposition of sludge, and sludge with aged urban solid waste has a better result; the addition of the two modifier can delay the appearance of peak concentration of organic in leachate; the addition of aged urban solid waste will make a better condition for the production of methane.
