Abstract: The aim of this study is to identify the pollution control technology system of municipal solid waste (MSW), and to provide a practical method of technology choosing of MSW treatment and disposal. Five main elements (C, H, O, N, S) were chosen to analyze the material and elementary flow of MSW by integrating the key technologies of MSW treatment and disposal. Many analysis methods such as Analytic Utility Process, Analytic Hierarchy Process, Analytic Uncertainty Process and Analytic Information Integration Process, were used to construct a material flow and economy optimization model. The assumed conditions, boundary conditions and initial conditions were defined, and the methods of Mento-Carlo numerical simulation and sensitivity analysis were studied. The optimization methodcan be used practically in the decision making of MSW treatment and disposal technology.
