Description
Technical field
The present invention relates to the technical field of kitchen garbage processing, more particularly to the kitchen waste compost dresses of a kind of desalination oil removing
It sets and method.
Background technology
China human mortality is numerous, and with the improvement of the quality of life, kitchen garbage yield is increasing.Kitchen garbage provides at present
Source utilization ways include anaerobic ferment for methane, aerobic compost, fodder etc., wherein press life cycle analysis, kitchen garbage
Compost substantially may be summarized to be：The circulating cycle of " edible-discarded compost-means of agricultural production fertilizer-Soil Utilization of agricultural production-agricultural product-"
Phase, therefore compost meets scientific and reasonable circulation pattern, kitchen garbage has also obtained extensive popularization for compost treatment at present
Using.However, the grease and salt content of China's kitchen garbage are high, butt fat content between 20%-30%, butt sodium
Content is between 1-3%, and since kitchen garbage salinity is high, oil is high, aerobic microbiological is new old during kitchen waste compost
Metabolism is adversely affected, and especially salinity is the most apparent to the inhibiting effect of aerobic microbiological, is unfavorable for organic matter degradation.Separately
On the one hand, high salinity, high oil content kitchen waste compost product do not welcome by market, using the composting production, to soil ring
Border quality causes damages, as the presence of salinity accelerates the soil salinization；The presence of oil influences soil water-retaining water suction, water-permeable and air permeable
Structural character.It can be seen that exploitation desalination oil removing kitchen waste compost method is extremely urgent.
Such as the patent document of application number 201410214382.8, kitchen garbage heat is disclosed except grease desalination high temperature anaerobic is dry
Fermentation system, the hot oil removing salt device of kitchen garbage make the grease in kitchen garbage and other objects through data acquisition integrated system control
Matter detaches, and floats on layer waterborne, fat content and salinity in fat content and salinity on-line detector detection supernatant liquid, and will
Data import data and acquire integrated system, when fat content in supernatant liquid and salinity meet condition, the integrated system of data acquisition
Supernatant liquid, is discharged in grease-water store tank by system opens solenoid valve by the outlet of the hot oil removing salt device of kitchen garbage；Oil
Grease-water mixed liquid body in fat-water store tank detaches grease and water through oil water separator, in saltwater-storage tank
Brine desalinates water through reverse osmosis film water saline-water reclamation device, in the water injection hot oil removing salt device of kitchen garbage after desalination
It is recycled.The Low grease of the hot oil removing salt device middle and lower part of kitchen garbage, the kitchen garbage of Low-salinity are dosed to high temperature and detest
High-temperature anaerobic fermentation, output biogas are carried out in oxygen digester.This belongs to except grease desalination process is using conventional oily water separation technique
In pretreatment scope, fails to realize inside anaerobic digestion process and remove grease desalination, and overall craft long flow path, operating cost
It is high.
Such as the patent document of application number 201310418533.7, recycled again after disclosing a kind of kitchen garbage desalination and desalination
The processing method utilized is removed by the way that the optimal control of electrolytic condition is realized the desalination to solid kitchen garbage and decomposed,
Pass through being preheated to 55 DEG C -110 DEG C and acid medium is added adjusting and pH value and be electrolysed kitchen to pending kitchen garbage
Salinity in rubbish makes its swill pH value reach and be maintained at particular range, to make the salt in solid kitchen garbage successively by
Abjection is dissolved among swill, and salt ionization is conveniently converted to the substances such as sodium hypochlorite, has achieved the effect that desalination desalination.
And secondary sodium chloride simultaneously can by swill long bacterium and short bacterium and other impurities aoxidize the other harmless molecules of generation together, make most
The natural fertilizer obtained eventually can reach and can recycle.Meanwhile treated that swill can also reach discharging standards, it is thoroughly real
Existing kitchen garbage is turned waste into wealth, and the purpose of recycling, produces significant social enviroment protection and economic benefit.This method is adopted
The problem of being required to consume additional electric energy with preheating electrolysis mode desalination heating and electrolysis, and not considering how except grease.
For this purpose, we have proposed a kind of kitchen waste compost device and methods of desalination oil removing.
