House refuse treatment method

Abstract

The invention discloses a house refuse treatment method, which comprises the following steps: crushing and fermenting refuse at normal pressure and under normal pressure; executing a screening process, crushing large or large-grain inorganic materials among oversize materials on a coarse screen, and making an urban coal material; coarsely screening, crushing stone and brick blocks among oversize materials on a medium screen, and making a roadbed material or pavior brick base material; making fertilizer by using organic materials or fermented products of the organic materials among the oversize materials and undersize materials of the medium screen and a fine screen, wherein materials with recycling value among magnetic materials screen out are sold directly, and materials without recycling value are collected and subjected to innocent treatment; and performing manual sorting, wherein materials with recycling value are directly sold. When the method is used for refuse treatment, the construction investment is small, the operation cost is low, the operation is simple, the treatment effect is desirable, and the resource recycling degree is high. The method can be widely used for treatment of refuse of different sizes and qualities without causing secondary pollution.

Description

technical field [0001] The invention relates to a garbage disposal method. Background technique [0002] Due to the limitations of national conditions and economic strength, the current domestic waste, especially urban waste, is mainly treated by simple stacking, sanitary landfill, incineration and composting. These treatment methods have their own benefits, but they all have some problems and deficiencies. This restricts the development of waste disposal in my country. [0003] The stacking method is to pile up garbage into a garbage mountain or naturally fill ditches and pits. It is the most primitive and traditional method of dealing with municipal solid waste. Although this method is simple and easy to implement and saves investment, it occupies a large area and causes serious pollution. Garbage is very easy to produce toxic liquids. After weathering, leaching, surface runoff erodes soil, pollutes air and water bodies, it can not only poison the microorganisms in the so...

AI Technical Summary

Problems solved by technology

However, the outstanding problems of traditional composting are: backward process technology, repetitive and cumbersome process routes, too long production cycle, too large floor area, unstable fermentation quality, and improper disposal of glass iron in the fertilizer, which seriously affects the fertilizer. Use effect, resulting in high investment and production costs, poor product sales, and serious land waste

However, the aerobic fermentation technology adopted in this invention should be carried out in a semi-sealed fermentation bin, and the aerobic fermentation is carried out by using the hydraulic jet vacuum pumping method, which requires relatively high requirements for the site and equipment, and the investment and construction costs are relatively high. Running costs are also higher

And the treatment process also includes incineration procedures, which will produce certain pollution

In addition, this treatment method is only suitable for the treatment of organic waste, and cannot deal with mixed waste, so it is not widely used
