Embodiment Construction

[0034] Such as figure 1 Shown, a kind of method for centralized treatment of kitchen waste of the present invention, it comprises the following steps:

[0035] (A) Sorting of kitchen waste;

[0036] Since food waste is a high-concentration organic waste, it is easily corrupted and produces odors. Therefore, restaurants and restaurants pack and process food waste. In addition, food waste is not classified, and the things used on the table are everywhere in food waste. . Therefore, belt breaking, screening and crushing processes are designed during the treatment process, that is, food waste is transported from the unloading bin to the bag breaking machine in turn for bag breaking and screening in the sifter, and the sieved ones larger than 70mm Particles such as chopping boards, bones, etc. and lighter garbage such as broken plastic bags are sent to the airtight cleaning vehicle through the conveyor belt, and sent to the landfill for landfill. Particles greater than or equal t...

Abstract

The invention relates to a centralized kitchen waste treatment method which comprises the following steps of: (A) sorting kitchen waste; (B) separating oil from water; (C) treating oil; (D) treating sewage; and (E) treating odor. Compared with a traditional kitchen waste burying method, by using the centralized kitchen waste treatment method, a great amount of soil is saved and an available methane resource is generated, kitchen waste reaches 100 percent of harmlessness, more than 95 percent of resource utilization and more than 95 percent of quantitative reduction, and the harmless treatmentof waste and the recycle of resources are truly realized.

Description

technical field [0001] The invention relates to a method for centralized treatment of kitchen waste, in particular to a method for centralized treatment of harmless, reduced and resourceful food waste from restaurants and restaurants. Background technique [0002] For a long time, food waste has been neglected and managed out of order. It is mainly bought by some criminals at low prices to raise pigs and refine waste oil, and secondly enters landfills and sewers. Since the sundries in the food waste and the toxins produced by fermentation will accumulate in the pig body, it will also have an adverse effect on the health of the eater, and may also cause the infection and spread of zoonotic diseases. Lawbreakers use kitchen waste to refine food waste oil, circulate it into the oil market, and then enter the food chain of urban residents. It has also been reported many times in China that residents were poisoned by eating food processed from kitchen waste oil. The discharge o...
