Abstract: Leachates with different ages (3~12 years)collected from same landfill were investigated. The results show that COD, TOC in leachates decrease with disposal time increasing;TOC/COD is 0. 40 to 0. 10 from 3 years to 12 years. Meanwhile,the composition of leachates was prepared through two separation ways such as vacuum drying and freeze drying and TGA and IR were used to analyze inner composition. The results show total solid (TS)in leachate reaches more than 30 000 mg/L;the composition obtained by freeze drying is 13% ~39% higher than that by vacuum drying.
