Garbage sorting treatment method

Abstract

The invention provides a garbage sorting treatment method which occupies small area, can avoid pollution and effectively treat toxic gas, has no residue and is short in treatment time, low in operation cost, high in product quality and free of secondary pollution. According to the technical scheme, the garbage sorting treatment method is characterized by comprising the following steps: drying, performing dust screening, winnowing, crushing, de-magnetizing, winnowing, performing water separating, crushing, winnowing, hydrolyzing and discharging hydrolyzed garbage from a hydrolysis tank.

Description

technical field [0001] The invention relates to the technical field of garbage collection, in particular to a method for sorting garbage. 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 waste generated is increasing and the growth rate is getting faster and faster (increasing at a rate of 6% per year), and its composition is becoming more and more complex. It is an indisputable fact tha...

Problems solved by technology

This method seems to be simple, but it is very harmful. Its disadvantages are: it occupies a large area and takes a long time. Increase

On the surface, this method seems to have achieved the reduction and recycling of waste disposal, but there are also the following problems: 40-50% of the slag after incineration still needs to be reprocessed, and it needs to be landfilled to continue to pollute groundwater and soil

[0006] The third is composting. This method has the advantages of low investment and easy operation, but it has the following disadvantages: the composting of organic matter takes a long time, and the degradation of organic matter is not complete

[0007] To sum up, my country's current domestic waste treatment technology is basically at a low level, and it is difficult to achieve harmless, resourceful and industrialized waste treatment.
