Method of efficiently and rapidly consumption kitchen waste by utilizing earthworms

Abstract

The invention discloses a method of efficiently and rapidly consumption a kitchen waste by utilizing earthworms. The method comprises the following working procedures that kitchen waste collection, reduced-weight sorting, deoiling treatment, desalination treatment, crushing treatment, dehydration treatment, high-temperature curing treatment, adding palatable substances to form earthworm special-purpose feed, and consuming the kitchen waste through an earthworm rangeland; in a process that the kitchen waste is consumed through the earthworm rangeland, the earthworm special-purpose feed and a matrix soil are loaded into a earthworm breeding box to form the earthworm rangeland; fresh earthworms are put into the earthworm rangeland; 4-7 breeding boxes are built into one group to be placed in abreeding greenhouse; the earthworms are used for consuming the kitchen waste in 80-96 hours or within; and then the earthworms and wormcast are processed in a separating mode. According to the method, the earthworms can grow healthily, the eating is fast, the propagation is good, and the kitchen waste in a corresponding proportion can be consumed to no residue in 96 hours or within; after the earthworms are used for consuming the kitchen waste, the earthworms and the wormcast are processed in the separating mode, and the wormcast is prepared into a high-grade organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of biodegradation treatment of kitchen waste, and in particular relates to a method for using earthworms to digest kitchen waste. Background technique [0002] Food and kitchen waste includes two sources, one is food and beverage waste formed by residents in the process of living consumption, and the other is perishable waste generated by vegetable farms, which accounts for 40%-62% of urban domestic waste. The main components include food residues such as rice and flour, vegetables, animal and vegetable oils, meat and bones, etc.; kitchen waste, mainly organic matter, is the source of municipal solid waste corruption and secondary pollution. High moisture content and high organic matter content make kitchen waste easily corrupt and deteriorate, causing great difficulties for temporary storage, collection, transportation and treatment. At the same time, spoiled kitchen waste will produce a large amount of ha...

AI Technical Summary

Problems solved by technology

(2) The landfill produces a large amount of harmful gas

(3) Landfill leachate pollution is serious

(4) Landfills that have not been covered by pest control are also prone to white pollution and breeding of flies and mosquitoes

However, there are still some problems in the existing technology of using earthworms to digest kitchen waste: (1) The source of kitchen waste is very complicated. The proportions are not the same; salt and spicy taste are the natural enemies of earthworms, and their content is relatively high. Not only do earthworms not like to eat them, but they also threaten the life of earthworms, and even bring the hidden danger of land salinization to vermicompost; (1 ) The technology of "earthworm hotbed" and "earthworm pasture" is backward, which is not conducive to the survival, eating and digestion of earthworms. The growth of earthworms is unhealthy, the rate of waste absorption is slow, and the excretion is slow.
