摘要: During leachate recirculation, a bioreactor landfill will experience more rapid and complete settlement, which is mainly attributed to the weight of municipal solid waste (MSW) its biodegradation. The settlement MSW may cause decrease void ratio MSW, influence permeability quantity that can be held in landfills. In this study, new one-dimensional model recirculation using infiltration pond developed. method not only capable describing flow considering effect but also accounting separately saturated unsaturated zones. Moreover, effects operating parameters are evaluated with parametric study. analyzing results show depth smaller than value without effect. volume increase pressure head ratio. This indicates field compaction has great on recirculation.
