%X Landfill bioreactor is a new international development field in the municipal solid waste management. It can reduce the difficulty of leachate treatment and accelerate the landfill stability process. The general moisture distribution rules in landfills were analyzed in this paper and a three dimensional transient mathematical model was established to simulate the saturated unsaturated moisture movement under the condition of leachate recirculation to landfills. The model was solved by Galerkin finite element method and tested with Theis well formula. The functions of different leahcate recirculation designs in landfill bioreactors were implemented in the model. Thus, the moisture movement in the landfill could be simulated under the condition of leachate recirculation, which provides theoretical basis for the effective design and operation of landfill bioreactor.
