Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0038] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0039] Such as Figure 1-2 As shown, a method for harmless disposal of urban waste comprises the following steps:

[0040] Step 1: Preliminary high-temperature shrinkage treatment is performed on the bagged garbage through high-temperature treatment equipment, and then the bagged garbage treated by high-temperature shrinkage is transported to the screen in the drainage pool 10 for extrusion cutting and bag breaking treatment, and the bag is broken through the screen vibration Draining treatment for at least 1 hour; wherein, the sieve also includes a sieve I 101 and a sieve II 102 ...

Abstract

The present invention relates to the technical field of resource recycling, in particular to a method for harmless treatment of urban garbage, comprising the following steps: after the bagged garbage is preliminarily subjected to high-temperature shrinkage treatment, the bagged garbage is transported to a screen in a drainage pool for squeezing, cutting, and bag breaking and sieve vibration drainage treatment; sieve the garbage after vibration drainage treatment into relatively heavy garbage and relatively light garbage; relatively heavy garbage is hammered and crushed by hammering components, and then screened out ferromagnetic recycling and non-ferrous Magnets, and then sieve non-ferromagnetic materials to obtain tough garbage, brittle garbage and rigid garbage; combine relatively light garbage and tough garbage to separate dry tough garbage and wet tough garbage; incinerate dry tough garbage Treatment; wet tough waste is used to prepare organic fermented fertilizer; rigid waste and brittle waste are fired into building bricks. The method of the invention realizes harmless treatment of garbage, does not cause pollution to the environment in the whole process, and realizes a sustainable circulation system.

Description

technical field [0001] The invention relates to the technical field of resource recycling, in particular to a method for harmless treatment of urban garbage. Background technique [0002] With the development of the economy, the continuous increase of the population and the improvement of people's living standards, the amount of urban waste generated is also increasing. In today's world, a large amount of garbage has become a long-standing source of pollution in cities. Environmental pollution by garbage has become an increasingly serious social problem. [0003] Municipal waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. 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 landfill. Although the method is r...
