Method for treating perishable materials using black soldier flies

Abstract

The invention relates to a method for treating perishable materials using black soldier flies. The method comprises the following steps: respectively performing pulverizing and dewatering treatment onperishable materials in mixed municipal domestic waste and real-time graded perishable materials in resident households to obtain first perishable materials and second perishable materials, respectively conveying the first perishable materials and the second perishable materials into a first perishable material section and a second perishable material section to perform treatment, and using larvae of the black soldier flies to perform treatment on the first perishable materials and the second perishable materials; after the treatment process, performing separation on the larvae of the black soldier flies and the excrement of the black soldier flies, and performing thorough decomposing treatment on the separated excrement of the black soldier flies to obtain organic fertilizer; and applying the separated larvae of the black soldier flies as living protein feed to culture of aquatic products or / and livestock and poultry, or performing drying treatment. The method for treating the perishable materials using the larvae of the black soldier flies does not need fermentation, shortens a process chain, does not pollute underground water, does not generate foul smell, does not breed mosquitos and flies, does not influence the surrounding environment, has high treatment capacity of perishable materials, can generate huge economic benefits and realizes virtuous ecological cycle.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for treating perishables by using black soldier flies. Background technique [0002] Perishables are perishable kitchen waste, kitchen waste, melon skin and fruit stones, vegetable leaves and other organic matter that are separated by mechanized fine classification of municipal solid waste or that are classified by household residents in real time in their daily lives. It accounts for about 30%-60% of the mass ratio in municipal solid waste, and its moisture content is above 80%. Among them, the perishables separated by mechanized fine classification of municipal solid waste will also be mixed with impurities, such as dust, flowers, branches and leaves. If the perishables are landfilled, it will not only produce stench and breed mosquitoes and flies, but also produce a large amount of leachate, which increases the difficulty of treatment; incineration i...

Problems solved by technology

The light-spotted soldier flies collected by this method at the pre-pupa stage have entered the old age, the cortex thickens, and the color begins to turn black. When used as livestock and poultry feed or aquatic feed, the taste becomes poor, and the weight of the insects decreases, and the income decreases.

In addition, adding auxiliary materials to food waste reduces the processing capacity of food waste

[0007] None of the above-mentioned materials mentioned the treatment method for the perishables mixed in domestic waste
