Family type kitchen garbage biological circulation processing system and method

Abstract

The invention belongs to the technical field of solid waste resource treatment, biomass resource treatment and ecological cycle economy, and discloses a family-type kitchen garbage biological circulation processing system and method. Kitchen garbage on that day is collected, chopped and processed; the chopped kitchen garbage and wheat bran are mixed according to the ratio being 1:1 to prepare flour weevil larvae feed, and the feed is put into a flour weevil larvae breeding box; and flour weevil fecula sand is collected to make organic fertilizer or potted plant food. According to the family type kitchen garbage biological circulation processing system and method, the kitchen garbage produced each day in a family is collected from the source to be converted into high-worth fecula sand and polypide albumen through feeding of flour weevil, the fecula sand can serve as the fertilizer to be applied to a balcony vegetable garden, and the garbage goes back to a kitchen and a dining-table through vegetable picking. The complex feeding habits of the flour weevil larval are used, and the kitchen garbage with the complex ingredient are eaten; meanwhile, insects do not urinate due to the special intestinal tract (malpighian tubule) condition, the problem of environmental pollution of the kitchen garbage in the flour weevil fecula biotransformation process is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of solid waste resource treatment, biomass resource treatment, and ecological circular economy, and in particular relates to a family type kitchen waste biological cycle treatment system and method. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: kitchen waste refers to perishable organic waste such as fruits, vegetables and food scraps, leftovers, melon and fruit peels discarded in daily life, mainly solid waste. Among the material components of kitchen waste, starch, dietary fiber, protein, and animal and vegetable fats account for more than 95% of the dry matter. At present, the commonly used kitchen waste treatment technologies at home and abroad mainly include (1) mechanical crushing treatment method. This treatment method mainly smashes kitchen waste and sends it to the sewer. Higher requirements. (2) Anaerobic digestion is the current ma...

AI Technical Summary

Problems solved by technology

[0005] (1) The mechanical crushing method uses the sewage treatment system to degrade organic matter, which has high requirements on the urban sewage treatment system, and discharges organic solid waste into the sewage treatment system, which increases the burden of sewage treatment and causes a waste of resources

[0006] (2) The anaerobic digestion method to treat kitchen waste realizes the volume reduction and recycling of kitchen waste through microbial degradation. It has a high degree of automation, requires less manpower, and is easy to control. The products have the advantages of diversification and high economic value; but Microorganisms have high requirements on pH, relatively complicated treatment technology, foul smell in the reactor, and long start-up time for internal biomass

[0007] (3) The aerobic composting method requires a large area of ​​treatment site, and the composting process is prone to produce unpleasant odors, causing environmental pollution, and the economic benefits are not high
