The invention provides a centralized domestic garbage classified treatment process. The centralized domestic garbage classified treatment process comprises the steps that domestic garbage is sorted firstly, and inorganic inert garbage, organic easy-to-corrode garbage and recyclable materials are obtained after sorting; the inorganic inert garbage is transported to a burial site to be buried; the organic easy-to-corrode garbage is subjected to organism-microorganism grading digestion treatment; and the recyclable materials are reutilized. According to the centralized domestic garbage classifiedtreatment process, the domestic garbage can be divided into the three types of the inorganic inert garbage, the organic easy-to-corrode garbage and the recyclable materials; and the organic easy-to-corrode garbage in kitchens and the like are treated through a resource utilization technology with organism-microorganism grading digestion, the high-valued recyclable materials are in butt joint witha downstream renewable resource recycling enterprise, and the inorganic inert garbage enters a sanitary landfill to be treated finally.
