Problems solved by technology

[0005] The prior art has the following defects: (1) The lack of description of the specific treatment method for food waste recycling; (2) The parameter control of the food waste pretreatment (crushing, solid-liquid separation) is not carried out, resulting in rapid and good recovery. The effect of oxygen fermentation is not good; (3) The process and parameters of the rapid fermentation process of food waste are not strictly controlled, resulting in poor fermentation effect; (4) The maturity of the secondary compost output is not judged, resulting in Poor understanding of fertilizer maturity; (5) Failure to clean the solid-liquid separator, oil-water separator, and pipelines, resulting in blockage of solid-liquid separators, oil-water separators, and pipelines

Embodiment 1

[0045] see figure 1 , which shows a resourceful treatment method for food waste according to an embodiment of the present invention, a method for resourceful treatment of food waste, comprising the following steps:

[0046] S10, sorting: sorting the collected non-pure food waste, sorting out the non-food waste, and waiting for the food waste to be processed;

[0047]S20, crushing: crushing the sorted food waste to obtain a solid-liquid mixture of food waste with a particle size of 2-4 cm;

[0048] S30, solid-liquid separation: performing solid-liquid separation on the solid-liquid mixture of the food waste obtained by crushing to obtain a solid food waste residue and a liquid water-oil mixture, wherein the water content of the solid food waste residue is 50% to 65%;

[0049] S40, rapid aerobic fermentation: add aerobic fermentation bacteria and auxiliary materials to the solid food waste residue, supply a preset range of temperature and a preset range of oxygen volume concent...

Embodiment 2

[0056] On the basis of embodiment 1, see figure 2 , also includes S90, cleaning the solid-liquid separator, oil-water separator, and pipes. After the treatment is completed, clean the solid-liquid separator, oil-water separator, and the pipes connecting them with the ozone-cleaning water generated by the ozone dissolution generator.

[0057] System Embodiment 1

[0058] see image 3 , a food waste resource treatment system, adopting the above food waste resource treatment method, including a sorter 10, a pulverizer 20, a solid-liquid separator 30, a food waste biochemical processor 40, and a secondary composting device 50 , oil-water separator 60, waste water treatment device 70 and soap powder machine 80, wherein,

[0059] The sorting machine 10 is connected with the pulverizer 20, the sorting machine 10 sorts the food waste, and sorts the non-food waste, and the pulverizer 20 pulverizes the sorted food waste to obtain a particle size of 2-4cm solid-liquid mixture of food...

Abstract

The invention discloses a kitchen waste resourceful treatment method and system. The method comprises the steps of sorting, smashing, solid-liquid separation, rapid aerobic fermentation, secondary composting, oil-water separation, wastewater treatment and soap powder manufacturing. The kitchen waste resourceful treatment method in the prior art is perfected; parameter control is conducted on kitchen waste pretreatment (smashing and solid-liquid separation) so as to improve the fermentation efficiency and guarantee the fermentation effect; process and parameter control is conducted on the rapidaerobic fermentation process of kitchen waste so as to improve the fermentation efficiency and guarantee the fermentation effect; the decomposition condition of secondary composting products is preliminarily judged so that fertilizer can be collected and detected in time; and an ozone dissolution generator is additionally arranged so that a solid-liquid separator, an oil-water separator and a pipeline can be cleaned regularly, and the solid-liquid separator, the oil-water separator and the pipeline are prevented from being blocked and stinking.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and relates to a method and system for resourceful treatment of kitchen garbage. Background technique [0002] Kitchen waste, commonly known as slops. It refers to the waste and residual waste formed by residents in the process of food processing and consumption, and is a kind of urban organic waste. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc.; its chemical components include starch, cellulose, protein, lipids and inorganic salts; in addition, it also includes a small amount of seasoning agents, waste tableware, Napkins and toothpicks, etc. Although the composition, properties and output of food waste will vary with regions and seasons, all food waste has the following characteristics: 1) high moisture content; 2) perishable and smelly, easy to breed germs, Can cause the spread of disease; 3) nutritious, de...
