Kitchen waste rapid fermentation method

Abstract

The invention a kitchen waste rapid fermentation method which comprises the following steps: 1) starting a blast apparatus; 2) laying a conditioner in a composting tank; 3) uniformly spraying effective microorganisms on the conditioner; 4) pouring the kitchen waste on the conditioner, and uniformly mixing to obtain a mixture 1; 5) pouring the conditioner on the mixture 1, and spraying the effective microorganisms to obtain a mixture 2; 6) pouring the kitchen waste on the mixture 2, and uniformly mixing to obtain a mixture 3; 7) establishing a pile; 8) after the pile material is fully stacked in the whole composting tank, laying an odor-inhibiting gas-permeable membrane; 9) carrying out intermittent air blast primary fermentation for 14-21 days to obtain fermentation residues; and 10) transferring the fermentation residues into another tank, repeating the steps 7) and 8), and carrying out intermittent air blast secondary fermentation for 5-10 days to obtain the rotten stockpile manure. The pile is established in the composting tank, the intermittent air blast fermentation is simultaneously adopted, and the effective microorganisms are added, so the time of the whole fermentation process is shortened by 10-50%.

Description

technical field [0001] The invention relates to the field of cleaning and treatment of degradable solid waste, in particular to a rapid fermentation method for kitchen waste. Background technique [0002] Kitchen waste is a substance with high oil content, contains too much protein, cellulose, etc., and is easy to stink. Waste disposal generally adopts operations such as landfill, which is relatively defective. Therefore, it can effectively solve kitchen waste, and using kitchen waste composting is the best treatment method, which is very environmentally friendly. [0003] At present, the traditional kitchen waste composting methods mainly fall into two types: trough type and strip stacking type: the trough type composting method uses a fermentation tank to carry compost materials, and the fermentation process is generally completed in the workshop, which is likely to cause local anaerobic and produce a lot of odor . The strip-stack composting method directly stacks materi...

Problems solved by technology

[0003] At present, the traditional kitchen waste composting methods mainly fall into two types: trough type and strip stacking type: the trough type composting method uses a fermentation tank to carry compost materials, and the fermentation process is generally completed in the workshop, which is likely to cause local anaerobic and produce a lot of odor

The strip-stack composting method directly stacks materials into strip stacks with triangular or trapezoidal sections. Generally, it is stacked in the open air, with low investment and flexible processing scale. However, the odor cannot be effectively controlled during the composting process, which is likely to cause air pollution. In particular, the precipitation process has a greater impact on the effect of strip-stack composting

[0004] In addition, the above-mentioned two types of traditional kitchen waste composting methods of trough type and stack type are natural microbial fermentation, but the types and quantities of microorganisms in the environment are limited, the initial stage of fermentation is slow, and some organic matter in kitchen waste is not completely degraded. , the ideal compost product cannot be obtained at all, so the growth of microorganisms requires relatively stable conditions, otherwise the effect of accelerating the degradation rate of organic matter and shortening the fermentation time will not be achieved.
