Recirculation is considered as an dual effective way of processing the leachate and accelerating the stabilization of landfill in many treatment because of less land occupation, low investment and simple operation. Previous researches shows that recirculation can improve microenviorment of microbial anaerobic digestion by increasing the moisture content of landfill. The mathematical model of moisture migration in the landfill was established with Multi-physics finite element analysis software in this paper. The simulation result showed that 1) moisture content would decrease to 29% with no leachate recirculation condition 2) hydraulic loads and types of recirculation both had influences on water distribution in landfill sites with leachate recirculation.
