Description
Technical field
The present invention relates to a kind of food and drink waste water oil removal treatment system, the field of waste water treatment belonged in environmental protection.
Background technology
In sanitary sewage, catering oily wastewater is the main water body of one kind therein.Numerous dining room, dining room, food processing
Enterprise and resident's daily life, which can discharge, largely contains sewage, wherein containing substantial amounts of animal and plant fat, if without place
Direct method is managed, the blocking of pipeline, the muddiness corruption of water body can be caused and grow source of curing the disease.
At present, existing sewage from catering business deoiling method includes following four.
（1）Physical mainly include be separated by filtration method, dissolved air flotation method, but be only applicable to separate waste water in particle compared with
Big oil product, treatment effeciency are 60~80%, and oil content is about 100~200 mg/litres in water outlet.Tiny oil droplets in waste water and
Oil emulsion is then very difficult to remove.
（2）The advantages of chemical Treatment is low cost of equipment, high treating effect, simple to operate；Shortcoming be need constantly to
Chemical agent is launched in waste water, its operating cost is high, and can introduce secondary pollution.
（3）Physical-chemical process mainly includes Bubble-floating Method, absorption method, electrochemical process, ultrasonic separation method etc., these methods one
As it is all adaptable relatively strong, selectivity is wide the advantages of.
（4）Biochemistry（It is biochemical）Facture is the biochemical action using microorganism, and the organic matter of complexity is decomposed into letter
Single material, so as to which noxious material is converted into innocuous substance, it is purified oil-polluted water.Microorganism can be using organic matter as battalion
Material is supported, is absorbed into a portion for the organic principle in microbial body or is proliferated into new microorganism, remaining
Part can be resolved into simple organic or inorganic material by microbiological oxidation.
Because above-mentioned traditional administering method has the shortcomings that certain, therefore, it is necessary to break away from existing Treatment process road
Line, the new way of processing sanitary sewage oil removing is hewed out, and then develop a kind of sanitary sewage oil removal treatment technology of new type.
The content of the invention
To solve the deficiencies in the prior art, the invention provides a kind of food and drink waste water oil removal treatment system, this is
System includes cache pool, coarse rack, microvesicle air supporting oil adsorbent equipment, oil catalysis, and neutralizing is inhaled reactor, pH value regulating reservoir, once sunk again

The outlet for depositing pond connects coarse rack by waste line, and the outlet of coarse rack connects microvesicle air supporting oil absorption dress by waste line
Put, π-allyl Ni compound modification infusorial earth adsorbed film in microvesicle air supporting oil adsorbent equipment can be by not after complete absorption oil
The steel mechanical arm that becomes rusty captures, and is admitted to oil and is catalyzed to dissolve again and inhale reactor, and the heavy oil generated in suction reactor is dissolved in oily catalysis again
Discharge and be recycled from heavy oil outlet, meanwhile, the outlet of microvesicle air supporting oil adsorbent equipment is connected by waste line
PH value regulating reservoir, the outlet of pH value regulating reservoir connect primary sedimentation basin by waste line, and the outlet of primary sedimentation basin, which passes through, gives up
Water pipeline connects organic rhodium catalysis reactive tank, the outlet of organic rhodium catalysis reactive tank by waste line connecting secondary sedimentation basin,
The outlet of secondary sedimentation tank connects water purifying tank by waste line, and the outlet of water purifying tank passes through waste line by the purification after processing
Arranged outside water outlet；Wherein, microvesicle air supporting oil adsorbent equipment bottom is equipped with 9 ultra-fine bubble generators, can on the liquid level of device
A laterally disposed π-allyl Ni compound modification infusorial earth adsorbed film is accommodated, its left upper portion is equipped with inlet valve, right
Side bottom is equipped with flowing water Valve, and the device right side wall is inhaled reactor because of the oil catalysis with high temperature again neutralizing and is connected, therefore is covered with
Aerogel blanket thermal insulation layer, aerogel blanket thermal insulation layer top are equipped with stainless steel machinery arm and ball bearing；Wherein, oil catalysis is dissolved again
Inhale reactor bottom and 5 electric heating air blast blower fans are housed, a set of stainless steel membrane frame is installed inside device, 5 are placed vertically on film frame
π-allyl Ni compound modification infusorial earth the adsorbed film for treating high-temperature process is opened, its bottom right is provided with heavy oil outlet；By
The food and drink waste water that coarse rack tentatively removes big particle diameter material is entered by the inlet valve of microvesicle air supporting oil adsorbent equipment left upper portion
Enter inside device, 9 ultra-fine bubble generators are started working, and produce the superfine air bubble that diameter is less than 50 μm, ultra tiny gas
The oil molecule carried secretly in waste water of steeping oneself-meeting together floats, and it is inhaled by the π on liquid level-allyl Ni compound modification infusorial earth
Membrane adsorbs, and π-allyl Ni compound modification infusorial earth adsorbed film of absorption oil completely is captured by stainless steel machinery arm, and by
The vertical stainless steel membrane frame for being placed on oil catalysis and dissolving in suction reactor again on, 5 electric heating air blast blower fans of reactor bottom can
To produce 200 ~ 250 DEG C of high temperature air, under the catalysis of π-allyl Ni compound, the c h bond in oil molecule can occur short
Temporary fracture, and quickly in conjunction with for C-C keys, C-C keys are then because the catalytic action of π-allyl Ni compound is limited without again
It is broken, therefore the shorter oil molecule of carbochain can be made gradually to synthesize the longer heavy oil molecules of carbochain, meanwhile, heavy oil molecules meeting
Desorbed at high temperature from π-allyl Ni compound modification infusorial earth adsorbed film, the heavy oil after convergence on the right side of reactor bottom
Outlet is discharged；Wherein, the outer layer covers of organic rhodium catalysis polymerization reaction trough have cell body insulating protective layer, the upper right quarter of reactive tank
