Embodiment 1

[0028] Embodiment 1: as figure 1 Shown, a kind of novel urban domestic refuse processing technique, the concrete steps of described novel urban domestic refuse treating technique are as follows:

[0029] Step 1: The domestic waste transport vehicle puts the waste to the beginning of the assembly line;

[0030] Step 2: The garbage in the garbage bag is scattered through the tearing bag system, which can completely disperse the garbage in the garbage bag and prepare for the subsequent further sorting. Then enter the low-temperature deodorization device for disinfection and deodorization to reduce the irritating temperature, thereby reducing the physical discomfort of the workers on the assembly line. Then enter the infrared drying system to dry the moisture in the garbage, reduce the moisture in the garbage, and reduce the phenomenon of entanglement between garbage, which is conducive to accurate sorting in the subsequent process;

[0031] Step 3: Garbage enters the continuous...

Abstract

The invention relates to a novel town household garbage treatment process, and belongs to the field of waste treatments. The process finely and comprehensively sorts household garbage through such sorting technologies as disinfection, deodorization, bag breakage, screening, magnetic separation, eddy current separation, winnowing, bounce separation and far infrared sorting. The process accurately classifies and sorts braided fabrics, waste papers, plastic, magnetic metal, nonmagnetic metal, glass, tile particles, soil, organic matters and the like, and produces the organic matters as organic fertilizers for use. The process combines such methods as machinery, automatic control and microorganisms, and adopts such technologies as a sewage comprehensive treatment and recycling and a deodorization technology; the whole system is high in automation degree; original mechanical-biological sorting method and device under a fluid environment are fully closed; few workers directly participate in the operation; mixed household garbage can be classified and sorted; the garbage recycling rate reaches above 95%; and sewage, dust, germs and virus in the treatment engineering are all treated and controlled without generating secondary pollution.

Description

technical field [0001] The invention relates to a novel process for treating domestic garbage in cities and towns, and belongs to the technical field of waste treatment. Background technique [0002] With the growth of China's population, the acceleration of urbanization, the development of economy and the continuous improvement of people's living standards, the amount of municipal solid waste is increasing day by day. According to incomplete statistics, the amount of garbage generated per person per day is about 1.2-1.6Kg. In 2013, the total amount of urban garbage generated was about 173 million tons, and in 2015 it was about 260 million tons. It is estimated that by 2020, the total amount of urban household garbage It will reach about 323 million tons, with an annual growth rate of nearly 5%. At present, the total amount of urban waste in stock has exceeded 6 billion tons, and the problem of environmental pollution is becoming more and more serious, and it is urgent to a...
