Description
Technical field
The utility model relates to a kind of ozone combined flocculation deposition processing units of cattle manure biogas slurry.
Background technique
Evaluation of biogas project on husbandry farms is widely applied as poultry excrement and urine disposal, energy recovery technology in China, passes through biogas work
Journey, which handles these fecal sewages, can not only mitigate environmental pollution, can also provide clean energy resource --- biogas, therefore biogas work
Journey is developed rapidly and promotes, and the ecomodel of " supporting a natural pond one to fill " is widely adopted, and is increasingly valued by people.
Biogas residue, which by anaerobic fermentation can be used as organic fertilizer material and return soil, to be utilized, however biogas slurry is with for liquid, amount greatly, mobility
Strong and easy occluding device becomes the typical pollutant of agricultural, tremendous influence and pressure is brought to environment, if improper conduct oneself well
Reason, while polluted water resources, can also cause the derivative problem such as land deterioration, and certainly will will affect China's agricultural economy can
Sustainable development.However a large amount of biogas slurries of most of livestock and poultry farm biogas project discharges lack enough soils and are dissolved,
Bring pollution problem is also more serious.Especially in recent years, row's phenomenon is commonplace steathily for biogas slurry, pours into field and leads to not plant
Crops is planted, causes serious puzzlement to nearby residents, biogas slurry, which once enters, is seeped into underground water, has not only damaged environment, can also make
At health problem.
Although anaerobic digestion can remove the great amount of soluble organic matter of high concentrated organic wastewater, in anaerobic digestion solution still
So contain a considerable amount of organic pollutants, belongs to high concentrated organic wastewater, containing a large amount of dark brown macromolecule humic acid, so that
The color of biogas slurry seems very deep, and light transmittance is also remarkably decreased.Biogas slurry waste water quality has following features: 1, solid colloid content
It is high, it is difficult to be separated by solid-liquid separation.Biogas slurry class after fermentation contains a large amount of gluey fine particle, has a large amount of detritus acid etc. on colloid
Organic compound, and with substances such as N P and Ks, it is good base manure raw material, theoretically analysis is good foliage organic fertilizer
And the raw material of ferment fertilizer.But since during the water of anaerobism natural pond, a large amount of nitrogenous compound after hydrolysis, fails complete first
Alkanisation, forms nitrogenous compound or amino-compound, these substances have stronger electropositive, and the electrical phase with solidity object
Together, resistance is generated, suspended state is caused, conventional isolation techniques is caused to be difficult to be separated by solid-liquid separation；2, the biodegradability of biogas slurry is poor.In natural pond
During prepared by gas, the residence time of anaerobism is too long, and under conditions of anaerobism, the degradation rate of BOD will be significantly faster than COD's
Degradation rate, therefore, the biodegradability of biogas slurry are poor, it is difficult to continue biochemical treatment.Therefore it is badly in need of seeking a kind of the effective of biogas slurry
Processing unit, realize biogas slurry can settling property while, reduce supernatant pollutant concentration, lighten the load for subsequent processing.

The utility model principle: ozone is produced using ozone generator, using ejector by ozone and cattle manure biogas slurry
It is sent into ozone reactor through water inlet aeration tube together, using the strong oxidizing property of ozone by organic compound difficult to degrade in waste water
Oxygenolysis resolves into and is conducive to biodegradable small-molecule substance, and will be most of difficult to degrade organic after ozone oxidation
Object is converted into degradable material, promotes B/C value, by dark brown macromolecule humic acid oxidase, reduces biogas slurry coloration, is conducive to subsequent
Processing is collected using bubble trap tube in the gas that ozone reactor generates, is sent into bubble trap, the cow dung after ozone oxidation
Fermentation biogas slurry enters in flocculation tank through outlet pipe, and crystal aluminum chloride is put into flocculation tank using flocculation administration device,
Flocculation reaction is carried out under magnetic stirring apparatus effect, cattle manure biogas slurry is sent into sedimentation basin and is precipitated after flocculation reaction, sinks
It is discharged behind shallow lake through sedimentation basin water outlet, in flocculation and precipitation unit by flocculation and precipitating, coloration is greatly lowered, fabulous mentions
High biogas slurry can settleability, and the COD value of cattle manure biogas slurry is effectively reduced.
The utility model advantage: one, using ozone generator, and gas flowmeter and ozone concentration analyzer, energy are set
The dosage of real-time monitoring and adjustment ozone；Two, using ejector, ozone is mixed with cattle manure biogas slurry, and pass through water inlet
Aeration tube is sent into ozone reactor, comes into full contact with ozone with cattle manure biogas slurry, guarantees the strong oxidizing property of ozone by waste water
In oxidation of organic compounds difficult to degrade decompose or resolve into and be conducive to biodegradable small-molecule substance；Three, setting flocculation is thrown
Medicine device effectively controls the dosage of flocculant (crystal aluminum chloride).Four, the initial COD of cattle manure biogas slurry is 19000mg/L
~24000mg/L, in ozone reactor after ozone Oxidation Treatment, after oxidation the COD of cattle manure biogas slurry be 10000mg/L~
The removal rate of 16000mg/L, COD are 45%~47%, after flocculation and precipitation process, cattle manure biogas slurry after processing
COD is 3000mg/L~5000mg/L, and the removal rate of COD is 70%~83%, and settling ratio reaches 20% when separation of solid and liquid, most
Cattle manure biogas slurry is as clear as crystal after the processing obtained eventually.
