Description
Technical field
The utility model relates to a kind of processing unit of waste water more particularly to a kind of processing units of kitchen waste water.
Background technique
As the improvement of people's living standards, China's kitchen industry is increasingly flourishing, kitchen garbage is also therefore a large amount of to be generated.These
Rubbish major part is sent to landfill yard together with house refuse and directly fills, and also some is commonly used by people for stock raising, very
To the refinement for being used for hogwash fat by criminal.In order to rationally utilize kitchen garbage, solve the wasting of resources and health hazard these
Problem, relevant policies regulation is issued, and kitchen garbage will be handled by centralized collection.
Kitchen garbage is in solid-liquid mixing in appearance, and main component is starch, animal tallow, crude fibre, protein
Equal organic substances, water and a small amount of inorganic salts.Kitchen garbage generally has the following characteristics that (1) content of organic matter is higher, such as carbon water
Compound, crude fat, carbohydrate and content of cellulose are very high, and the potentiality of resource utilization are big.(2) salt ionic concentration is very high, China
Between 2-6g/L, the salt ion of such high concentration can cause its anaerobic fermentation methane phase salt concentration range in kitchen garbage
Certain adverse effect.(3) fat content is higher, and grease contained in kitchen garbage has andvegetable fats and edible oil, mainly
It is made of long chain fatty acids (LCFAS) and triglyceride.Under the action of anaerobe, triglyceride can degrade generation
LCFAS and glycerol.Wherein LCFAS has obvious inhibiting effect to anaerobe, and a large amount of greases may cause sludge by grease
Package floats and outflow reactor.
Since kitchen garbage is that liquid consolidates mixture, so first having to liquid when kitchen garbage is handled containing oil
The kitchen garbage, waste-water of rouge is mutually separated with solid organic solid, then again respectively to the kitchen waste water of liquid and solid-state kitchen rubbish
Rubbish is handled.The common processing technique of solid-state kitchen garbage mainly includes compost, in line, the anaerobic digestion methane phase of crushing etc..
Liquid kitchen waste water is directly difficult qualified discharge using conventional biological treatment due to being rich in grease.Current main processing side
Method includes: gravitational separation process, coagulant sedimentation, gas floatation process, A/O method etc..
The necessity of advantage and disadvantage and wastewater treatment based on the prior art, studies the processing technique of kitchen waste water, to reduction
Water pollution, protection environment and resource utilization have great significance.In view of kitchen waste water biodegradability containing greasy is strong,
Therefore, the grease and subsequent biochemical processing technique in waste water are separated, is to influence water treatment effect and whether up to standard be discharged
Key.In addition, be separated by solid-liquid separation after solid refuse can with anaerobic fermentation, and in liquid kitchen waste water due to contain a large amount of salt
Ion and grease can cause strong inhibiting effect, therefore need to carry out before handling if directly carrying out biological treatment to microorganism
Oil removing and desalination.
Utility model content
The utility model aim is in view of the deficiencies of the prior art, to provide a kind of efficient kitchen waste water processing unit.
The kitchen processing unit of the utility model, successively include coarse rack pond, fine fack pond, oil removal-electric flocculation flotation tank,
Electrical adsorption desalting device, IC reactor, biological contact oxidation pond, activated carbon filter and clear water reserviors；Wherein, the oil removal-electricity
Flocculation-air floating pond is made of gravity oil separator and electrocoagulation flotation tank two parts；It is provided with just in the electrical adsorption desalting device
Negative carbon electrode, the carbon electrode are arranged in parallel；Rotational flow shearing air bubble aerator list is set in the biological contact oxidation pond
Member and composite filling.
Further, mechanical grille machine is set in the grid pond, automatically removes retention residue.
Further, the anode of electrocoagulation flotation tank uses stainless steel plate using aluminium sheet, cathode, and alternating is spaced at equal intervals,
Mechanical Slag Scraping Device is arranged at electrocoagulation flotation tank top, and bottom sets blow-down pipe.
Further, IC reactor includes reactor body, from top to bottom successively include gas-liquid separation zone, precision processing area,
Sludge bulking bed area and water distribution area.
Kitchen garbage tentatively realizes the separation of solid and liquid of waste water by the multiple impurity trapped of thickness grid, then by every
Oil-electric flocculation flotation tank, further eliminates part vegetable and animals oils, SS and COD；Carbon electrode anode in electrical adsorption desalting device
Electrostatic field is formed with carbon electrode cathode and adsorbs water intermediate ion, to realize desalination, and is able to achieve the company of electrical adsorption desalting device
Continuous regeneration.Granule sludge is launched in IC reactor, based on de-salting operation has been carried out before Anaerobic Treatment, so IC anaerobic reactor
In do not occur acidification phenomenon；Composite filling is that made of developing on the basis of soft-filler and semi soft packing, have specific surface
Product is big, coefficient of oxygen utilization is high.Composite filling surface with microbial film, have gap can be changed, not block, water distribution gas distribution performance it is good
The advantages that, sludge bulking and sludge reflux problem is also not present in aerobic process.Since the setting of filler plays cutting to bubble
And barrier effect, the surface area of the residence time and gas-liquid contact that make bubble increase, therefore improve the absorbability of oxygen, can subtract
Few aeration quantity.In biological contact oxidation pond, waste water contacts extensively with the microbial film on filler, in bacteria metabolism function
Under the action of energy, the organic matter in sewage is removed, and is purified the sewage.Waste water utilizes active carbon after biochemical treatment
The suspended matter in removal water body is adsorbed and is separated by filtration, clear water is discharged into clear water reserviors, realizes processing up to standard.
The utility model compared with prior art, has following substantive distinguishing features and remarkable advantage:
(1) separation of solid and liquid of kitchen waste water is realized using multiple tracks grid, and electric flocculation air bearing pool equipment is simple, land occupation face
Product is small, has preferable removal effect to animal and plant fat, SS and COD in kitchen waste water, deoiling effect is very significant.
(2) just one-step desalting is carried out to kitchen waste water using Electro Sorb pond, avoids the acidification phenomenon of subsequent anaerobic processes, greatly
Biochemical Treatment is improved greatly.
(3) during biochemical treatment, preferably IC reactor and biological contact oxidation pond combination technology, COD and NH4 +- N's
Removal rate has respectively reached 85% and 91%.Later use active carbon further adsorbs and crosses SS in drainage, final to guarantee water outlet
Water quality is completely up to standard.
