Efficient garbage sterilization, disinfection and classification treatment method

Abstract

The invention relates to the technical field of resource recycling, in particular to an efficient garbage sterilization, disinfection and classification treatment method. The efficient garbage sterilization, disinfection and classification treatment method comprises the following steps that bagged garbage is conveyed to a vibrating screen arranged in a water draining tank for vibrating and water draining treatment, and meanwhile, high-temperature bag breaking and stirring equipment is also used for stirring treatment; hammering and crushing treatment is carried out on the garbage subjected tovibrating and water draining treatment, and then relatively heavy garbage and relatively light garbage are screened out; ferromagnetic substances are screened out from the relatively heavy garbage tobe recovered, non-ferromagnetic substances are screened out from the relatively heavy garbage, and then screening treatment is carried out on the non-ferromagnetic substances to obtain tough garbage,brittle garbage and rigid garbage; the relatively light garbage and the tough garbage are combined, and then dry tough garbage and wet tough garbage are separated out; incinerating treatment is carried out on the dry tough garbage; the wet tough garbage is used for preparing an organic fermented fertilizer; and the rigid garbage and the brittle garbage are used for being fired into building bricks. According to the method, harmless treatment of the garbage is achieved, no pollution is caused to the environment in the whole process, and a sustainable circulation system is achieved.

Description

technical field [0001] The invention relates to the technical field of resource recycling, in particular to an efficient garbage sterilization and classification treatment method. Background technique [0002] At present, the annual output of domestic waste in my country is about 150 million tons, and it is increasing at an annual rate of 8%, while the annual stockpiling of waste in my country has reached more than 6 billion tons, occupying a large amount of land resources. It is estimated that among the 668 cities in my country, about two-thirds of them are surrounded by garbage. [0003] Municipal waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. [0004] There are three traditional disposal methods for urban waste: landfill, composting and incineration. Both landfill and composting need to occupy a large area and cause pollution to the environment. Landfill method is to transport waste to landfill for ...

AI Technical Summary

Problems solved by technology

This method has a long incineration cycle, and there is no waste heat utilization, and there is no corresponding flue gas deacidification and dust removal environmental protection process, which is easy to pollute the environment
