The invention provides an equipment facility-matched technology for preparing fertilizer by using household garbage and particularly provides a whole set of technology for preparing the microbial organic fertilizer by using the household garbage and the theoretical basis of the technology. Each working procedure of the technology is equipped with equipment (facility) matched with the corresponding technology, and the working procedures are joined with one another, so that a whole technology chain can be formed, wherein the technology chain comprises the following steps of: 1, deodorizing, drying, and coarsely picking; 2, separating by a high and vertical multi-floor; 3, preparing pulping refining material; 4, removing heavy metal ions, and carrying put biological anaerobic fermentation; 5, mixing by extruding dehydrating materials; 6, carrying out solar energy high-temperature mineralization reaction fermentation; and 7, preparing double-coordination microbial organic fertilizer finished product. The technology can solve the defects of the landfill method, the burning (electricity generation) method, and the composting process for treating household garbage and is a new method; and the technology is suitable for preparing the fertilizer by using the sludge and the offcut of the agricultural and sideline products, thereby providing a new way for improving the ecological environment and developing the organic agriculture.
