Abstract

Isotope tracer technique was used to separate released MSW moisture from rainfall in leachate to study leachate generation characteristics. Four cylindrical PVC landfill reactors (height: 0.2m, diameter: 0.16m) filled with different kind of man-made waste were compared to study the influence of MSW type on leachate quality and quantity. Rainfall infiltration releasing process was not seriously influenced by MSW type. More than a half of rainfall was released in the first 3 days (A1:57%, A2:68%, A3:77%, A4:53%). However, the proportion of released moisture in the first 5 days to total period time varied a lot in the four reactors (A1:46%, A1:35%,A3:12%,A4:9%). MSW with much kitchen waste was easy to degrade and the leachate releasing process concentrated in the first few days, while waste with much paper released water in a constant rate during the whole experimental period. Moreover, the moisture releasing process had an obviously relevance and regulation with degradation process. This study confirmed that initial moisture in solid could not be ignored especially in China where MSW was of high moisture content and biodegradable organics fraction.
