Abstract:
     The invention relates to an integrated method for processing municipal life waste, which comprises: collecting and classifying, separating, mechanically dewatering, fermenting and dewatering, burning, treating smoke, and collecting the slag to be used. Wherein, the dry waste after classifying and collecting can be separated into waste metal, waste glass and waste plastic, to be directly used; the wet waste via dewatered by compressing vehicle, mechanically compressed dewatered and fermenting dewatered can reach more 25% of dewatering total efficiency; the low-level caloricity of waste wet base is improved to 5990kg/kJ; the burning temperature is kept at 950-1050Deg. C, with high caloricity recycle rate; and the burning smoke has lower contents of dust, hydrochloride, heavy metal and dioxins; the smoke processing system has lower cost; and the slag has stable property, which can be used as cement blending material after magnetically selection and secondary grinding, or replace some cement. The invention can realize the integrated utilization of slag.
