Efficient aerobic composting technology for kitchen garbage

Abstract

The invention discloses an efficient aerobic composting technology for kitchen garbage. The process consists of: 1) starting air blasting equipment; 2) laying a conditioner in a composting groove; 3) dumping the kitchen garbage on the conditioner, then laying a layer of conditioner on the kitchen garbage, then dumping kitchen garbage on the well laid conditioner, and mixing the substances uniformly to obtain a mixed material; 4) piling the mixed material into a strip heap; 5) piling up the whole composting groove with the material, and performing covering with an odor depression and vapor-permeable membrane; 6) conducting intermittent air blast primary fermentation for 20-30d to obtain a fermentation residue; and 7) transferring the fermentation residue to another groove, repeating the step 4) and step 5), and carrying out intermittent air blast secondary fermentation for 7-14d, thus obtaining a product. The efficient aerobic composting technology for kitchen garbage provided by the invention adopts heap building in the composting groove, reduces the diffusion of odor in the kitchen garbage transportation process, at the same time employs intermittent air blast, can reduce pile turning and ensure aerobic fermentation within the pile, reduces odor generation, and the obtained compost has high quality.

Description

technical field [0001] The invention relates to the field of cleaning and treatment of organic solid waste, in particular to a high-efficiency aerobic composting process 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 include three types: trough composting, strip composting and reactor composting. The trough composting method uses fermentation tanks to carry compost materials. The fermentation process is generally completed in the workshop, and the fermentation speed is slow and easy. Cause local anaerobic, produce more odor. The strip-s...

Problems solved by technology

[0003] At present, the traditional kitchen waste composting methods mainly include three types: trough composting, strip composting and reactor composting. The trough composting method uses fermentation tanks to carry compost materials. The fermentation process is generally completed in the workshop, and the fermentation speed is slow and easy. Cause local anaerobic, produce more odor

The strip-stack composting method directly stacks materials into strip stacks with triangular or trapezoidal sections, which are usually stacked in the open air, but it occupies a large area, and the odor cannot be effectively controlled during the composting process, which is easy to cause air pollution, and the environment and climate are especially It is the precipitation process that has a greater impact on the effect of strip-stack composting

For reactor composting, the fermentation process is generally completed in the workshop, which requires a closed workshop and high investment costs.
