An environment-friendly microbial method garbage treatment device and garbage treatment method

Abstract

The invention discloses an environmentally friendly microbial waste treatment device, which includes a treatment box. The inside of the treatment box is equipped with a grinding chamber, a microbial reaction chamber and an enzymatic hydrolysis product processing chamber from top to bottom, and is equipped with a crushing cylinder, a reaction pot and a product classification. Purification device, a rotating grinding and cutting device is installed in the crushing cylinder, and a uniform tumbling and stirring device is installed in the reaction pot. The efficient crushing of the rotating grinding device makes the garbage particles more finely divided, and the microbial enzymatic decomposition of organic matter in the garbage is faster. The uniform tumbling and stirring device It can fully and evenly contact the garbage with microorganisms, which improves the area of ​​initial garbage purification and the sterilization efficiency. The method includes crushing and grinding the garbage with a rotating grinding and cutting device, and then the garbage enters the reaction pot, and the microorganisms in the reaction pot carry out primary microbial treatment on the crushed garbage. Enzymatic hydrolysis reaction, the crushed garbage and microorganisms are evenly mixed, the enzymatic hydrolysis reaction efficiency is high, and the garbage purification treatment is more thorough.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to an environment-friendly microbial method garbage treatment device and a garbage treatment method. Background technique [0002] Municipal solid waste mainly refers to the solid waste generated by units and residents in the city in their daily life and life services. The output of domestic waste in my country is increasing at a rate of 8%-10% every year. With the rapid development of the economy and the improvement of living standards, the proportion of recyclable waste and organic waste in municipal solid waste is gradually increasing. During the process of garbage collection and transshipment, the organic matter in the garbage will rot and deteriorate, and even the excrement. If it is piled up randomly, pathogenic microorganisms will seep into the ground with the rainwater, pollute the groundwater source, and directly or indirectly endanger the environment of urban residents an...

AI Technical Summary

Problems solved by technology

[0004] (1) Landfill technology: The disadvantages are difficult site selection, land occupation, high construction and maintenance costs, and the recycling rate of waste resources is almost zero, and the generated waste seepage seriously threatens the groundwater system

[0005] (2) Incineration technology: Incineration can convert carbohydrates in garbage into carbon dioxide and water, but the infrastructure investment and transshipment costs are relatively high. Form secondary pollution and air pollution, easily destroy the protective layer of the earth

[0006] (3) Composting technology: relying on a wide range of microorganisms in nature to biochemically transform biodegradable organic matter into stable reproductive mass. The disadvantages are that the mechanization of waste composting is low, the quality of compost is not high, and the fertilizer efficiency is low. It is easy to cause re-accumulation , forming secondary pollution

[0007] The emerging technology of microbial treatment of garbage generally requires multiple steps and multiple equipment or places. There is no systematic device or equipment to sort and treat garbage. Therefore, the efficiency of garbage treatment is relatively slow, and there are few who can simultaneously remove garbage. Solid, liquid and gaseous organic matter, and seepage and odor are easy to leak, resulting in adverse consequences such as incomplete garbage removal and environmental pollution. Therefore, the microbial treatment of municipal solid waste has low efficiency and harmful effects of microbial treatment Defects such as gas overflow, garbage seepage flowing out of polluted land, etc.
