Problems solved by technology

[0017] First, the problem of emerging single biological treatment is that the treatment of kitchen waste is not thorough, and there are many garbage residues that cannot be treated;
[0018] Second, there are corresponding shortcomings in a single biological population, such as the germs carried by cockroaches, and insects such as black soldier flies, which can only be used to clean up kitchen waste in the larval stage

Embodiment Construction

[0056] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0057] Aiming at the problem of existing kitchen waste treatment, this embodiment provides such as figure 1 The ecological chain treatment method of the food waste shown. Including in the pretreatment area (4), the food waste is dehydrated in the food waste dehydration area (15), and the food waste is made into a maximum particle size of less than 3-4 cm in the food waste crushing area (16). Pile the pre-treated food waste in the pre-treated food waste storage area (17); then transfer the pre-treated waste to the pre-treated waste disposal area (10) by the crane (9), and the pre-treated food waste The kitchen waste mentioned above is put into feed and digested and decomposed by organisms such as cockroaches and earthworms;

[0058] The residual residue...

Abstract

The invention discloses an ecological chain comprehensive treatment method of kitchen waste, and relates to the field of waste treatment. The method comprises the steps that the kitchen waste is pretreated; the pretreated kitchen waste is digested through multiple kinds of primary organisms; and the kitchen waste and residual kitchen waste obtained after treatment are removed through anaerobic composting. Cockroaches and earthworms exceeding the bearing capacity of the ecological system can be fed to secondary consumers of chickens, toads and the like. Eggs and corpses of chickens and toads can be simply treated, protein bodies can be made, and the method can be used for biological reproduction of carnivorous furbearers.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an ecological chain kitchen waste digestion process, which utilizes the ecological chain to process kitchen waste. Background technique [0002] At present, the treatment methods of kitchen and other organic perishable garbage mainly include: crushing and direct discharge, landfill treatment, fertilizer treatment, and energy treatment. [0003] The inventor found in the research that there are at least the following disadvantages in the traditional kitchen waste treatment and the single biological treatment process: [0004] Disadvantages of crushing in-line processing: [0005] First, crushing and direct discharge increases the burden of urban sewage treatment; [0006] Second, it is easy to cause a large number of mosquitoes and germs to breed, which will lead to the spread of diseases; [0007] Third, the resources that can be used for recycling in the kitchen was...
