Description
Technical field
The invention belongs to field of environment protection, is related to daily-life garbage without environmental pollution treatment technology and utilization of resources technology, especially relates to
And a kind of Food waste treatment method based on bioconversion.
Background technology
Food wastes have the dual characteristicses of environmental waste and reusable edible resource.Changing food waste yield is big,
Water, grease and salt content are high, perishable smelly, become a great problem in puzzlement city；Meanwhile, its be rich in protein, starch and
The nutriments such as grease, are the biomass resource of reusable edible again.At present, the processing mode of food wastes is mainly defended
Raw landfill and burning, small part are processed with composting mode.Existing treatment technology is mostly by food wastes as urban waste
Thing fails to make full use of food wastes, there is many deficiencies treating.
In addition, the Chinese patent of Publication No. 101947535A discloses a kind of innoxious ecological ring of kitchen organic waste
Protect cycling and reutilization processing method (application number：201010243431.2), its main process is that organic waste is carried out pre- place
Reason, is put into stoste bacterial classification in rubbish, places into, then fly maggot is separated with feed, obtain
Fly maggot and maggot excrement, maggot excrement feed earthworm again, separate once per 7-10 days, obtain earthworm and wormcast fertilizer.The method can be realized
The harmless treatment of changing food waste, but there is following significant Railway Project when implementing：
1. do not adopt sealed environment, the new pollution such as the foul smell that can be introduced to environment and waste water to form secondary pollution；
2. overall specific processing equipment is not designed, it is impossible to accomplish that high-volume automation is implemented.
How using the processing mode of science, economical and practical processing means carrying out innoxious place to food wastes
Reason and the utilization of resources are current the art problems anxious to be resolved.
Therefore, it is necessary to design a kind of new restaurant garbage treating system.
The content of the invention
The technical problem to be solved is to provide a kind of Food waste treatment method based on bioconversion, the base
Hatching frame is sent into after changing food waste is pre-processed by the Food waste treatment method of bioconversion to raise insect acquisition maggot and have
Machine fertilizer, can carry out harmless treatment, and have economic benefit to changing food waste.
The technical solution of invention is as follows：
A kind of Food waste treatment method based on bioconversion, at based on the concentration hatching method of closed shell
Reason changing food waste；Comprise the following steps：

In step 3.2, it is 25-35 degree to control temperature, and humidity is 50%-70%.
Sewage disposal process in step 4 is：From the highly concentrated oil-bearing wastewater for oozing naturally drip, dewaterer Jing sewage pumpeds
2 grades of oil interceptors are entered by cistern, neutralized pond, coagulating basin and 2 grades of pneumatically supported methods again are put into after a small amount of flocculant, will
Water-In-Oil is changed into oil-in-water, thus oil is separated out and is floated, and centralized recovery is re-used as the raw material of industry；
Jing air-flotation process by the sewage after water-oil separating, then through A/O microbiological treatment combined treatment units, waste water is removed
In organic pollution, most after Jing sedimentation basin precipitation after directly discharge or flushing device recycling.
Waste gas is processed using ventilation and exhaust treatment system, ventilation and exhaust treatment system include aerofoil fan, air exhauster
And tail gas treatment device, oxygen supply (provide suitable biological viable conditions) is provided for bioconversion, while by biological activity
The foul smell of generation is processed (absorption, dissolving etc.), is discharged after reaching discharge standard.
Video monitoring apparatus and lighting device are provided with sealing shell.
Jing air-flotation process by the sewage after water-oil separating, then through A/O microbiological treatment combined treatment units, efficiently remove
Organic pollution in waste water, most after Jing sedimentation basin precipitation after directly discharge or flushing device recycling.As the present invention is adopted
With the above by changing food waste through crushing, processed, bioconversion, water-oil separating and biologic process for treating sewage flow process
Technical scheme so that changing food waste energy fast degradation, the final product for decomposing is the insect protein of high-quality, biological organic fertilizer and
Regeneration raw material of industry oil, and smelly water and foul smell that processing procedure is produced directly are discharged Jing after process is up to standard, non-secondary pollution.We
The biological treatment integrated system adopted by method include outer package, induction system, pretreatment system, ventilation and exhaust treatment system,
Crushing system, storage bin system, bioconversion systems, after-treatment system, warm and humid regulating system, sewage disposal system, profit point
From parts such as system, mixing system, dewatering system, monitoring systems, all it is special-purpose assorted equipment, using intelligent automation control
System, factorial praluction, with operating efficiently, automatically, energy-conservation, it is safe the characteristics of.The nontoxic free from extraneous odour of whole processing procedure, was processed
Journey is short, minimizing 100%, non-secondary pollution, and resource utilization degree is high, is a kind of economic benefit, social benefit and Ecological Effect
Beneficial significant method for organic waste disposal, has a good application prospect.
