Light movable vegetable waste anaerobic dry fermentation system and method for anaerobic fermentation by using light movable vegetable waste anaerobic dry fermentation system

Abstract

The invention relates to a light movable vegetable waste anaerobic dry fermentation system and a method for anaerobic fermentation by using the light movable vegetable waste anaerobic dry fermentation system. The system includes a pulverizer, a blending pool, a conveyor belt and an anaerobic dry fermentation device, wherein the pulverizer, the blending pool, the conveyor belt and the anaerobic dry fermentation device are sequentially connected; the anaerobic dry fermentation device comprises a plurality of anaerobic reaction bodies which are connected side by side, the anaerobic reaction bodies are provided with a solar panel thermally-insulated chamber as an outer cover, each anaerobic reaction body includes a reaction tank and a gas storage membrane, the adjacent gas storage membranes are connected through connection chains, and the adjacent reaction tanks are connected through connection chains. The system is simple in device and movable, planting and processing vegetable waste generated by an intensive vegetable area or scattered vegetable-growing households are subjected to the anaerobic fermentation to prepare biogas, an organic fertilizer is obtained, energy utilization of the organic waste in the vegetable area is achieved, the environment of the vegetable area is improved, the quality of vegetables is improved, and the land quality in the vegetable area is improved.

Description

technical field [0001] The invention relates to a vegetable waste treatment device in an intensive vegetable area, in particular to a light-duty movable vegetable waste anaerobic dry fermentation system and an anaerobic fermentation method using the system, belonging to the technical field of waste resource utilization. Background technique [0002] Since the implementation of the "Vegetable Basket" project in 1988, the output of vegetables in our country has continued to increase, the varieties have become more abundant, and the quality of life of the people has improved significantly. As a large vegetable country in the world, my country has a vegetable planting area of ​​more than 300 million mu and an annual output of more than 700 million tons, ranking first in the world in terms of vegetable planting area and total vegetable output. [0003] In the process of vegetable production and processing, roots, stems, leaves, rotten fruits and tail vegetables without commercial...

Problems solved by technology

Chinese patent document CN101734961A discloses a method for treating vegetable straw waste. Through research on the composition and properties of vegetable straw waste, a harmless treatment method is provided for concentrated stacking of vegetable straw waste and inoculation of compound microbial fermentation. , the method is relatively simple, but the processing time is long, the efficiency is slow, the harmful gas produced by stacking and fermentation pollutes the environment, and it cannot generate new energy biogas, and the effective resource recycling of waste has not been realized.

[0008] It can be seen that domestic scholars have done a lot of research on dry fermentation devices and methods for farm manure, straw and other wastes. At present, there are no relevant public reports on anaerobic dry fermentation devices for vegetable waste.
