Embodiment 1

[0052] Embodiment 1 A new type of kitchen waste short-process resource treatment process, the process flow is described as follows:

[0053] 1. After the food waste is transported by the special collection and transportation vehicle to the food waste resource treatment plant, it is first weighed and measured, and then enters the pretreatment workshop and passes through the unloading platform to unload the materials in the collection and transportation vehicle into the high-efficiency pretreatment system The receiving bin; the high-efficiency pretreatment system includes a secondary hydraulic separation process section and a static oil-water separation process section.

[0054] 2. The pretreatment module of the secondary hydraulic separation device removes most of the inorganic substances such as packaging bags, glass, and ceramics mixed in, as well as hard objects such as large bones and fruit shells that are easy to damage subsequent processing equipment, as non-degradable imp...

Abstract

The invention relates to the technical field of garbage treatment, in particular to a novel short-process resourceful treatment process for kitchen garbage. The novel short-process resourceful treatment process comprises the following steps that after the kitchen garbage is collected and transported into a factory, materials are subjected to centralized and rapid three-phase separation through anefficient pretreatment system, separated solid-phase materials are subjected to aerobic composting treatment, a product obtained after composting treatment is organic coarse fertilizer, and then the organic coarse fertilizer is subjected to fine processing treatment to be prepared into solid organic fertilizer; impurities separated in the composting process are sent to a refuse landfill to be subjected to landfill treatment or incineration treatment, separated grease provides a qualified raw material product for biodiesel, a separated liquid phase is subjected to anaerobic fermentation to generate a large amount of biomass biogas, and the biomass biogas can be used as fuel of a boiler to provide heat energy and electric energy for a plant area; and as for biogas slurry digested by an anaerobic system, one path of the biogas slurry is adjusted back to the aerobic composting system for humidity and strain adjustment, the other path of the biogas slurry is processed into composite microbial liquid fertilizer for sale, and treated wastewater is discharged after reaching the standard. Waste gas generated in the whole treatment process is biologically deodorized and then discharged afterreaching the standard.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a novel short-flow recycling process for kitchen garbage. Background technique [0002] The main components of food waste are starch contained in staple food, cellulose and pentosan contained in vegetables and plant stems and leaves, protein and fat contained in meat, etc. The content of PaCl in inorganic salts is the highest and it also contains a small amount of Ca and Mg , Fe, K and other trace elements. Its chemical composition is mainly C, H, O, PS, and Cl. Food waste is rich in organic matter, high in nutrients, complete in variety of nutrients, and high in water content. If it is not treated in time and is perishable, its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins. . From the point of view of the form of matter, the organic matter in kitchen...
