LANDFILL GAS GENERATION AND TRANSPORT IN BIOREACTOR LANDFILL
The activation gas and water flow each other in Bioreactor Landfill. Based on the porous media seepage and bio-degradation theory, the coupling mathematics model considered the effect of water and waste components decomposition for describing landfill gas flow have been developed, and the simulation cells are performed. The simulation results show: the gas moves almost horizontally when it collected by the well, and it transport towards the atmosphere continuous. The gas pressure was released by pumping in landfill. The landfill surface cover system increase the gas pressure, and it can effective restrains gas disorderly leaking and increases the gas flow rate. In the earlier, the flow rate is approximately decreased linear with time during the pumping process. The variation law is identical to the testing data. And the reliability of the coupling model was validated. It will provide the theoretical evidence and technological support to LFG pollution control and reuse on the study of gas flow law for Bioreactor Landfill.
