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 invention relates to the technical field of resource recycling, in particular to a harmless treatment method for municipal waste. The method comprises the following steps: after bagged waste is subjected to primary high-temperature shrinkage treatment, the bagged waste is conveyed to a screen in a water draining pool for extrusion, cutting, bag breaking and screen vibration water draining treatment; relatively heavy waste and relatively light waste are screened out from the waste subjected to vibration water draining treatment; the relatively heavy waste is hammered and crushed by a hammering assembly, then ferromagnetic substances and non-ferromagnetic substances are screened out for recycling the ferromagnetic substances, and then the non-ferromagnetic substances are screened to obtain tough waste, brittle waste and rigid waste; the relatively light waste and the tough waste are combined, and then dry tough waste and wet tough waste are separated out; the dry tough waste is incinerated; the wet tough waste is used for preparing an organic fermented fertilizer; and the rigid waste and the brittle waste are used for being burned into building bricks. According to the method, harmless treatment of the waste is achieved, no pollution is caused to the environment in the whole process, and a sustainable circulation system is realized.

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...
