Fermentation tank for solid waste treatment process and solid waste treatment system

Abstract

The invention provides a fermentation tank for a solid waste treatment process and a solid waste treatment system. The fermentation tank comprises a tank body extending longitudinally, wherein an isolation grate is arranged in the tank body, the edge of the isolation grate is fixedly connected with the side wall of the tank body, the isolation grate and the side wall and end wall of the tank body above are enclosed to form an accommodating tank used for accommodating sludge, the part of the tank body, below the isolation grate, forms an independent gas chamber, vent holes enabling the gas in the gas chamber to be communicated with the gas in the accommodating tank are formed in the isolation grate, N vertical plates are horizontally arranged in the gas chamber and divide the gas chamber into N+1 branch gas chambers longitudinally arranged, an air guide vertical plate is arranged in the branch gas chamber and divides the branch gas chamber into mutually independent swirl chambers, and a blast pipe for supplying air to each swirl chamber is further arranged on the side wall of the branch gas chamber. The fermentation tank can improve the aeration uniformity and promote the uniform fermentation of the solid waste, so as to shorten the fermentation period and improve the processing efficiency.

Description

technical field [0001] The invention relates to a solid waste treatment technology, in particular to a fermentation tank for a solid waste treatment process and a solid waste treatment system. Background technique [0002] The solid waste in this article refers to the livestock and poultry manure produced in the process of livestock and poultry breeding, and the sludge formed after domestic sewage and industrial sewage treatment (it is an inevitable product after sewage treatment), which is large in amount, and in order to avoid Its impact on the environment requires further harmless treatment. [0003] In the solid waste treatment process, it is necessary to place livestock and poultry manure, sludge, etc. in the fermentation tank, and pass oxygen into the fermentation tank, so that the microorganisms in it can react with oxygen, that is, aerobic fermentation, to produce useful waste. value of humus. The process of sending oxygen from the fermentation tank to the livestoc...

Problems solved by technology

[0005] But, in the fermenter that this strip extends, even if the aeration pipe at the bottom is evenly arranged, and guarantees that the air outlet is evenly arranged on the aeration pipe, but, in the whole fermenter, the solid waste that enters through the isolation layer The amount of gas (aeration rate) in the material varies greatly, and the aeration is uneven, resulting in a large difference in the degree of fermentation in different parts of the entire fermentation tank, which directly affects the treatment effect and efficiency.
