Problems solved by technology
[0003] 1. Existing waste disposal methods include many processing steps such as magnetic separation, sorting, drying, and crushing, which require more equipment, occupy space, and require high investment
[0004] 2. Food waste contains many microorganisms, germs, parasite eggs, etc., which cannot be killed by landfill, composting and other treatment methods

Embodiment Construction
[0015] like figure 1 As shown, after the food waste enters the sorting machine 3, the metal material in the waste is separated by the magnetic separator 2 first, and then the plastic bags, plastic lunch boxes and other plastic products in the food waste are separated by the sorting machine 3, and then sorted. The sorted food waste is transported from the bottom outlet of the sorter 3 to the dehydration and deodorization drying tower 4 through the airtight transmission pipeline. The agitator 7 is raised to the photocatalytic chamber 5. After the food waste is fed, the movable heat-resistant partition 10 returns to its original position, and the rotatable metal liner 12 with a mesh-like side wall starts to rotate at a high speed. The centrifugal force makes the The water contained in the food waste is discharged, flows out through the mesh of the side wall, and enters the filter device 14 from the drain outlet under the side wall of the drying chamber 6 through the pipeline. Aft...

The invention discloses a kitchen garbage disposal method. Garbage is disposed after being sequentially passing through a garbage storage box, a magnetic separator, a sorting machine, a dehydration, deodorization and drying tower, a photocatalytic chamber, a drying chamber, a stirrer capable of lifting and dropping, a far infrared heating lamp, an ultraviolet lamp, a removable heat-resisting partition plate, a movable heat-resisting partition plate, a rotatable metal liner with a reticulate side wall, a pelletizer, a filtering device, a top plate of which the inner side is coated with a photocatalyst, and a refrigerating device. According to the method, three steps of drying, deodorizing and crushing are completed in a disposal tower; garbage disposed by using the method is heated to a high temperature by far infrared light, so that most of parasitic ova and viruses are killed; and according to the invention, the moisture content of garbage subjected to drying treatment is 5-10%, which is lower than that in other methods; and the volume of garbage is further reduced.
Description
technical field [0001] The invention relates to a method for treating kitchen waste, which belongs to the field of solid waste treatment in environmental protection. Background technique [0002] Food waste is the domestic waste formed by residents in the process of living consumption. The main components include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the chemical composition, there are starch, cellulose, protein, lipid and Inorganic salt. The main characteristics of kitchen waste are rich in organic matter, high in water content, and 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. At present, the commonly used food waste treatment methods mainly include landfill, feed method, composting method, incineration method, pyrolysis method and biological method. [0003] 1. Existing waste dispo...
