摘　　要：The objectives of this study are to determine the characteristics of leachates generated from landfill lysimeters of municipal solid waste. Two lysimeters with diameter and height of 0.70 and 2.40 m, respectively, were prepared. The lysimeters were operated with and without leachate recirculation. The leachate produced were quantified and characterised every day for the quantity, pH and ORP （oxidation reduction potential）. Meanwhile, the BOD and COD parameters were characterised every once week. Based on the data of experimental results that the lysimeter with a recirculation gave positive effects on the degradation of waste in landfills, that is the degradation process becomes faster. This is indicated by the quantity and quality of leachate generated. The lyisimeter conducted with recirculation of leachate shew the quantity of leachate generated larger than the lysimeter without recirculation. While the quality of the leachate includes pH, ORP, made it shown that the degradation process is faster. These results operations, especially for young waste. BOD and COD indicate that leachate recirculation on lysismeter suggest that leachate recirculation can be performed on landfills
