Garbage classification treatment method for environmental sanitation

Abstract

The invention belongs to the field of garbage classification recycling treatment, and particularly discloses a garbage classification treatment method for environmental sanitation. The garbage classification treatment method comprises the following steps that garbage pretreatment is conducted, specifically, recycled garbage is classified, cleaned and dried to obtain clean garbage; garbage crushingis conducted, specifically, the garbage is crushed into garbage particles through a crusher; garbage screening is conducted, specifically, scrap iron in the garbage is removed through a garbage ironremoval screening device, the garbage particles are screened, and the multiple garbage particles with the same size are obtained after screening; the garbage particles are conveyed to a drying deviceto be subjected to substance drying treatment; and selection is conducted after drying treatment, specifically, the granular garbage substances are conveyed to a winnowing device, and light plastic, medium textile fabric and heavy plastic are obtained. According to the garbage classification treatment method, the garbage is subjected to the steps of cleaning, crushing, iron removal screening, drying, selection and the like, wood substances, plastic substances, fabric substances and metal substances are classified and recycled, the garbage is turned into wealth, and the recycling of the plasticgarbage and the like is achieved.

Description

technical field [0001] The invention relates to the field of sorting, recycling and processing of garbage, in particular to a garbage sorting and processing method for sanitation. Background technique [0002] According to statistics, about two-thirds of the cities in our country are currently surrounded by garbage. The annual output of municipal solid waste in my country alone is nearly 150 million tons, most of which are stacked in the open air. It not only affects the urban landscape, but also pollutes the atmosphere, water and soil that are vital to our lives, and poses a great threat to the health of urban residents. Garbage has become a very difficult problem in the process of urban development and social progress. Moreover, with the continuous improvement of people's living standards, the amount of domestic garbage produced is increasing, the growth rate is getting faster and faster (increasing at a rate of 6% per year), and the components are becoming more and more ...

Problems solved by technology

The landfill method not only occupies a large amount of land resources, but also causes serious secondary pollution to the land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration Serious air pollution poses a threat to people's lives and health; diversified treatment is to sort domestic waste and then process various items, but the existing sorting methods are not thorough in the classification of waste, and its resource utilization The rate is not high, still needs further improvement
