An anaerobic fermentation tank for solid organic waste using a horizontal electric field

Abstract

The invention provides a solid organic waste anaerobic fermentation box applying a horizontal electric field. The anaerobic fermentation box comprises a sealing door (1), an anaerobic fermentation chamber (2), a horizontal electric field generation system (3), a liquid storage chamber (4), a partition plate (5), a spraying system (6), a heat preservation system (7) and an air outlet (8). The two sides of the anaerobic fermentation chamber (2) are provided with a positive pole part (3a), a negative pole part (3b), a positive pole connecting wire (3c) and a negative pole connecting wire (3d). The horizontal electric field is formed in the anaerobic fermentation box after the anaerobic fermentation box is powered on, carbohydrate, protein, volatile acid and other dissolved organic matter produced through anaerobic fermentation of solid organic materials flow out at an increased speed along with percolate, and therefore the aerogenesis efficiency of the anaerobic fermentation box is improved. By means of the device, solid organic waste anaerobic fermentation methanogenesis efficiency can be promoted under the low voltage, anaerobic fermentation residue solid content is improved, and the follow-up treatment cost is reduced.

Description

Technical field [0001] The present invention relates to an anaerobic fermentation tank of solid organic waste, and more particularly to a solid organic waste anaerobic fermentation tank using a horizontal electric field. Background technique [0002] The disposal and resourceization of solid state organic waste has always been an important issue in the field of environmental protection. In recent years, the solid organic waste such as agricultural and forestry waste, agricultural product processing waste, dehydrated municipal sludge, and the number of kitchen garbage climbed in recent years. These solid waste contain a large amount of organic matter, if it is not possible to deal with, it will have a big threat to the environment. Currently, the treatment methods for these solid waste are mainly: landfill, compost, incineration, and anaerobic fermentation. This can be recycled while treating these waste while treating these waste, and its construction is relatively low. Therefore...

AI Technical Summary

Problems solved by technology

However, when the solid content of the anaerobic fermentation material is higher than 15%, its mass transfer performance becomes poor

The anaerobic fermentation products of solid organic waste are difficult to contact with anaerobic microorganisms, which reduces the efficiency of anaerobic fermentation methane production

At the same time, due to the high water content of anaerobic fermentation residues, the cost of using anaerobic fermentation residues for reuse is increased.

These current solid organic waste fermentation devices have not fundamentally solved these problems
