Unpowered aerobic fermentation method for solid waste biomass container

Abstract

The invention discloses an unpowered aerobic fermentation method for a solid waste biomass container. The method is used for performing unpowered aerobic fermentation on the solid waste biomass container by using the organic fertilizer stacking fermentation container, and comprises the following steps: mixing fermentation raw materials containing solid waste biomass and a nitrogen fertilizer, adjusting the carbon nitrogen ratio C: N to be (25-35): 1, adjusting the moisture of the materials to 55-65%, inoculating a fermentation inoculant, stacking the materials for 3 days, 3 days later, when no water seeps out of the materials, loading the fermentation materials into a box body module, assembling the fermentation container, standing for natural and rapid fermentation, not overturning in the midway, and when the temperature is reduced again to be close to the air temperature, finishing fermentation. Compared with an existing fermentation technology, the method has the advantages that the field, energy and labor cost are saved, the fermentation speed is high, environment friendliness is achieved, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation and relates to a non-powered aerobic fermentation method for solid waste biomass containers. Background technique [0002] Solid waste biomass has a high output and a wide range of sources, including: domestic waste such as kitchen and kitchen waste, residual sludge from sewage treatment plants, agricultural and forestry waste such as livestock and poultry manure, agricultural straw, etc., and food and pharmaceutical industry Waste, fermentation industrial waste such as distiller's grains, medicinal residues, biogas residues, etc. In addition to incineration and landfill, waste biomass treatment methods are mainly treated by microbial fermentation. Microbial fermentation can be divided into anaerobic and aerobic methods. [0003] Aerobic fermentation treatment methods currently mainly include the following types: [0004] Static strip-stack fermentation: The material is stacked in...

AI Technical Summary

Problems solved by technology

The disadvantages of static stack fermentation are: a. It takes up a lot of space; b. It requires a lot of manpower and energy consumption;

The disadvantages of the aerobic fermentation of the bar-type turning throwing machine are: a. It needs a large site, and usually needs to harden the site or build a factory building or a rainproof shed; b. It consumes more power (fuel consumption); c. Discharge of bad smell; . Operators are often in bad working conditions or environments, e. The cost of turning and throwing machines is high, the operating costs are high, and the failure rate is high

[0006] The disadvantages of trough-type overturning fermentation are: A. Large site requirements and high construction costs. B. Power consumption. C. Slow water loss. C. Odor. D. Long fermentation period. E. Civil engineering and mechanical equipment are fixed Larger asset investment

Disadvantages of air-flow membrane artificial gas explosion fermentation are: A. High cost of membrane and aeration fan; B. Large power consumption; C. Need more space, hardening of the site, high civil construction cost of fermentation tank; E. Uneven material fermentation , F. The fermentation effect is greatly affected by the sealing degree of equipment and civil engineering

[0008] The biggest problem facing all the above methods is that it is difficult to approve construction land, occupying a large amount of land, and it is difficult to obtain approval

At the same time, the energy consumption is high, which violates the principle of waste disposal
