Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. For brevity, the following description combines the devices and methods of the system together. as attached figure 1 As shown, the dumping and sorting process A is the front-end process of the method, and the kitchen garbage truck 1, the driving vehicle 2, and the garbage bucket 3 cooperate with each other to intermittently pour the kitchen garbage into the garbage separator 4; The solids in the garbage in 4 are divided into large miscellaneous and small miscellaneous, and the large miscellaneous is transported to the coarse pulverizer 9 through the belt conveyor 5. When necessary, manual sorting is set at the beginning of the belt conveyor 5, and the glass bottles, Plastic containers, etc. are sorted out and removed. A magnetic separator 8 is arranged on the top of the belt conveyor 5, so that the iron-containing impuri...

Abstract

The invention discloses a comprehensive food waste treatment system and a treatment method thereof, belonging to the technical field of environmental governance. Solids are recovered from the food waste to prepare composite protein feed, synchronously oil is recovered to prepare industrial articles, such as soap powder, bio diesel, fuel oil, and the like and the food waste water is recovered to prepare fertilizers so as to realize the aim of comprehensively utilizing the food waste. The system of the invention has reasonable design, various subsystems are mutually independent and mutually communicated to form a production line for rapidly treating the food waste; and the food waste treatment method by utilizing the production line is simple, convenient and practical, has extremely high treatment capability, turns waste into valuables and greatly solves the problem of urban environmental pollution. The production line of the invention can be used for treating 10-500 t of food waste every day, i.e. about 40 percent of the refuse quantity of a large city like Wuhan, and every 100 T of food waste can produce 8-12 t of rough protein feed, 2-4 t of refined crude oil and 50-70 t of liquid fertilizers.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a comprehensive treatment system for urban kitchen waste and a comprehensive treatment method for urban kitchen waste. Background technique [0002] In the prior art, the disposal methods of municipal waste usually include incineration and landfill. If municipal solid waste is incinerated, since the moisture content of kitchen waste is usually as high as about 90%, the calorific value is 2100kJ / kg-3100kJ / kg, and Incineration of other garbage together will not only fail to meet the heat generation requirements of waste incineration power generation (that is, more than 5000kJ / kg), but will cause the incinerator to burn insufficiently and produce toxic substances; The food waste has a high moisture content and is not suitable for disposal. Moreover, incineration and landfill will lead to a large amount of waste of organic matter. With the acceleration o...
