摘　　要：为实现垃圾填埋气的能源化利用以及渗滤液的高效处理，通过构建垃圾焚烧厂运营的系统动力学模型，寻找焚烧厂与其附近的垃圾填埋场之间的合作关系，利用填埋场的填埋气作为辅助供应能源，对焚烧厂产生的垃圾渗滤液进行回喷蒸发处理。以成都市区的某垃圾填埋场和焚烧厂为案例，模拟结果表明假设的合作模式是存在的。在保证焚烧厂经济效益的同时，最多从垃圾填埋场购入20％的填埋气，可回喷蒸发处理掉焚烧厂内40％的渗滤液，实现经济、环境的双赢。This paper presents a system dynamics （SD） approach to seek for a potential collaboration between a municipal incinerator and its nearby sanitary landfill, to evaporate waste leachate by using landfill gas as alternative energy source. A municipal solid waste incineration plant and a sanitary landfill in Chengdu city, China, are investigated as typical case examples to demonstrate the application of the proposed approach. The simulation result indicates that the model is valid, and the annual economic return of the incineration plant reaches the maximum whilst the optimal ratio of waste leachate for evaporation is 40%. The limitations of the SD model are then discussed for, laying a foundation for further work.
