Food waste treatment method

Abstract

The present invention provides a food waste in situ treatment method, which comprises: A, carrying out solid-liquid separation on food waste; B, carrying out a biochemical treatment on the separated solid waste in a treatment bin to form an organic fertilizer master batch; C, carrying out a composting treatment on the organic fertilizer master batch to form an organic fertilizer; and D, screening the organic fertilizer. According to the present invention, the food waste treatment equipment is placed on restaurants, party and government organs, enterprises and institutions, university sites and other waste generation places, the organic domestic food waste is regularly or irregularly treated before rotting so as to reduce the waste transfer link, and the harmless in situ treatment is performed to convert the food waste into the organic fertilizer master batch so as to achieve control of the food waste from the source, such that the waste transportation cost and the landfill burning cost are reduced, and the odor generation during the waste fermentation process is reduced, wherein the whole treatment process is completely sealed.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a method for treating kitchen garbage. Background technique [0002] The timeliness of waste disposal is very important. In the past, landfill, mixed incineration, direct feed processing, sorting and crushing, and then anaerobic fermentation and aerobic fermentation were usually used. [0003] Landfill disposal of waste not only requires a large storage capacity, but also causes secondary pollution of soil and groundwater by waste gas and grease, which will increase the load on the landfill, and with the increase of landfill volume, the difficulty will also increase. will increase. [0004] Using mixed incineration to treat garbage, because the liquid in the mixed garbage makes it difficult to burn, and the calorific value produced is low, which not only causes waste of energy, but also pollutes the environment.

AI Technical Summary

Problems solved by technology

[0003] Landfill disposal of waste not only requires a large storage capacity, but also causes secondary pollution of soil and groundwater by waste gas and grease, which will increase the load on the landfill, and with the increase of landfill volume, the difficulty will also increase. will increase

[0004] Using mixed incineration to treat garbage, because the liquid in the mixed garbage makes it difficult to burn, and the calorific value produced is low, which not only causes waste of energy, but also pollutes the environment

[0005] For the direct feed processing of waste, although it can generate high economic value, because the product enters the food chain again, it is difficult to avoid problems such as protein homology, and there are food safety hazards

[0006] In the treatment of anaerobic fermentation, secondary pollution will be caused due to improper treatment of biogas residue and biogas slurry.

[0007] The simple aerobic fermentation technology has a big taste when it is open to operate, pollutes the environment, and has the problem of incomplete decomposition of organic matter
