Fermentation device and microbial fermentation decomposition treatment method thereof

Abstract

The invention relates to a fermentation device and a microbial fermentation decomposition treatment method thereof. Specifically, treatment is carried out directly at a food waste generation site, food waste is placed into a specially set stirring and heating apparatus to perform decomposition by means of microorganisms that can decompose food waste at high speed, and then the left materials are separated from holes of different sizes. The treatment device treats the food waste into liquid through microorganisms, and according to differences of microorganism species, decomposition temperature, air injection amount and time, the decomposition degrees can also be different. However, the common feature lies in that, after particles pass through a filter screen disposed in front of a fermentation decomposition tank outlet and are dispersed, they are discharged in a suspension liquid state. The suspension liquid comprises 90% of water and the balance animal or vegetable oil. The solid state component is composed of microorganisms, ferment discharged after microbial fermentation, and the particles passing through the filter screen. The particles can be regarded as food fragments cut according to certain size.

Description

technical field [0001] The invention relates to the technical field of biotechnology, in particular to a fermentation device and a microbial fermentation decomposition treatment method thereof. Background technique [0002] Generally speaking, the food waste produced every day in households and restaurants contains a large amount of anaerobic or aerobic microorganisms and water. Once the waste is produced, it will produce stench caused by the fermentation of spoilage bacteria, and also breed other germs, seriously affect the environment and human health. [0003] Moreover, food waste disposal has become a very serious social problem, and various methods to effectively deal with food waste emerge in endlessly. For example, the burning method using an incinerator, the method of burying food waste, the method of reducing the amount of food waste in a dryer, and the method of reusing it as fertilizer or feed after fermentation in a fermentation machine, etc. [0004] When inci...

AI Technical Summary

Problems solved by technology

[0004] When incinerating food waste, a lot of energy and funds are required, and toxic gas is produced, which not only affects human health, but also pollutes the environment; when burying food waste, a large amount of sewage seeps out, which not only pollutes the environment, but also pollutes groundwater; the drying method Discharge harmful waste gas and waste water, etc., causing secondary pollution

At the same time, it consumes a lot of electric energy and emits carbon dioxide; when the fermentation method ferments food waste, it will produce stench, and if there are many oily components in the discharged water, it will pollute the environment and block the excretion pipe, which is very difficult to use
