Field Investigation On The Feasibility of Leachate Recirculation In Chengdu Msw Landfill, China
Abstract The paper presents a field investigation on the feasibility of recirculating concentrated leachate into the Chengdu landfill of municipal solid wastes. The field investigation included borehole investigation of the hydrogeological conditions and in situ simulation tests of leachate recirculation. Two kinds of facilities, i.e., open pits and vertical wells, were established to carry out the simulation tests. The borehole investigation revealed that the leachate level within the landfill was very high, being at a depth of 1∼3m below the landfill surface. The results from the simulation tests indicated that the steady-state recharge capacity into the open pit and vertical well were 24 m3/d and 5 m3/d, respectively, and the hydraulic-conductivity of waste was calculated to be 6.3×10-6 m/s. The low recharge capacity was mainly attributed to the high leachate level. Preliminary numerical analyses demonstrated that a drawdown of leachate level will result in an increase in the recharge capacity.
