Embodiment Construction

[0012] Combine now figure 1 Further explanations will be made on the technical means and process flow of the food waste resource treatment method of the present invention. It should be noted that this implementation case is only used as an explanation of the technological process described in the present invention, and does not constitute any form of limitation to the content protected in the claims of the present invention.

[0013] A resourceful treatment method for food waste, firstly realizing the solid-liquid separation of the food waste to be treated through a large-aperture inclined screen.

[0014] The aperture of the large-aperture slope screen is 16-25 mesh, and the slope angle is 45-60°. The specific parameters are dynamically adjusted according to the characteristics of different batches of kitchen waste.

[0015] The solid components that have completed the solid-liquid separation are pretreated by manually removing a small amount of impurities and simple crushin...

Abstract

The invention discloses a kitchen garbage resourceful treatment method. Firstly, solid-liquid separation and pretreatment are performed on kitchen garbage through a large-aperture inclined screen; solids are used for hermetia illucens cultivation; liquid further finishes oil-water separation; deep anaerobic fermentation is performed on water phases to obtain biogas; remained biogas slurry is addedin the solids for adjusting the water contents of the solids; and oil phases are added in the solids for balancing nutriment nutrition. The obtained biogas enters a gas oven for drying fresh hermetiaillucens and for drying wetter solids. The kitchen garbage resourceful treatment method can use the kitchen garbage for cultivating the hermetia illucens, uses garbage fermentation products for drying the fresh hermetia illucens, hardly needs additional energy in the garbage treatment process, and has the advantages of environmental protection, energy conservation and high resourceful utilizationrate.

Description

technical field [0001] The invention belongs to the field of waste treatment, and in particular relates to a resource treatment method for kitchen waste. Background technique [0002] Food waste disposal is a major difficulty in the field of waste disposal. Compared with domestic waste, food waste has the characteristics of high water content and oil content, and high organic matter content, which makes it difficult to use traditional landfill, incineration, dry distillation and other methods to treat food waste. And because food waste has a high nutrient content, it is a good microbial culture medium, which is easy to breed various pathogenic microorganisms such as bacteria. Improper control will become a medium for the spread of various diseases and increase the risk of illness in the crowd. [0003] The existing food waste treatment methods mainly include aerobic composting and anaerobic fermentation. Among them, aerobic composting mainly uses the metabolism of aerobi...
