Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of sewage decomposition apparatus of ortho-aminobenzoic acid, including acidification conditioning tank 1, flocculation sedimentation tank 3, Fenton's reaction pond
4, acidizing hydrolyzation tank 5, line settling tank 6 and contact-oxidation pool 7, covering at the top of the acidification conditioning tank 1 has shading tent, is acidified
1 side of conditioning tank is equipped with air-introduced machine 2, is equipped with aeration tube inside the acidification conditioning tank 1, and aeration tube passes through appendix
Road is connect with air blower；The acidification conditioning tank 1 is connect by pipeline with Fenton's reaction pond 4, in the Fenton's reaction pond 4
Hydrogen peroxide and ferrous sulfate are dosed；The Fenton's reaction pond 4 is connected with flocculation sedimentation tank 3, and flocculation sedimentation tank 3 through pipeline
In added coagulant and flocculation aid；The flocculation sedimentation tank 3 is connect by pipeline with acidizing hydrolyzation tank 5, the acidification
Contain a large amount of anaerobic bacteria in hydrolytic tank 5；The acidizing hydrolyzation tank 5 is connected with contact-oxidation pool 7, contact-oxidation pool through pipeline
Filler is set in 7, and contains a large amount of aerobic bacteria in contact-oxidation pool 7, and 7 bottom of contact-oxidation pool is equipped with aeration tube；
The contact-oxidation pool 7 is connect by pipeline with line settling tank 6.
The aeration tube is type micro-pore aerator.
The hydrogen peroxide is 3%.
The ferrous sulfate is 10%.
The coagulant is aluminium polychloride.
The flocculation aid is polyacrylamide.
Conditioning tank 1 is acidified for regulating pondage, balanced water quality, acidification conditioning tank 1 can at least accommodate production cycle
Waste water sets aeration tube in pond, prevents sludge from depositing and for being sufficiently stirred.Shading tent is covered on acidification conditioning tank 1 to avoid giving up
Water is irradiated through sunlight, in addition air-introduced machine 2 passes the gas through pipeline height row,
It is that catalyst carries out chemical oxidation with hydrogen peroxide (H202) that Fenton's reaction, which is with ferrous ion (Fe2+), by ferrous iron
Ion and hydrogen peroxide composition reagent be Fenton reagent, it can generate the hydroxyl radical free radical of strong oxidizing property, in aqueous solution with
Hardly degraded organic substance generates organic free radical and is allowed to structure destruction, final oxygenolysis.It is useless by treated in Fenton's reaction pond 4
CODcr can be greatly lowered in water, significantly increase BOD5.
Dosing coagulant and flocculation aid in the waste water of flocculation sedimentation tank 3, enable the particle for being difficult to precipitate to be aggregated with one another and shape
At colloid, bigger floccule body is then formed in conjunction with the impurity in water body.Floccule body has powerful adsorption capacity, can not only adsorb
Suspended matter, moreover it is possible to which absorbed portion bacterium and dissolved matter, floccule body are increased and sunk by absorption, volume, the SS in waste water
It substantially reduces.
Hydrolysis acidification technique be a large amount of anaerobic bacterias effect under by insoluble hydrolysis of organic matter be dissolved organic matter, will be difficult
Biodegradable macromolecular substances are converted into the process of the small-molecule substance of easily biological-degradable, so as to improve the biochemical of waste water
Property, it creates conditions for subsequent biochemical.
Filler is set in contact-oxidation pool 7, bottom of pond aeration is oxygenated sewage, and sewage in pond is made to be in flow regime,
Waste water comes into full contact with filler in pond, and pollutant is by the aerobic bacteria adsorption-decomposition function on filler.It is aerated supply oxygen by air blower,
When biofilm development is to certain thickness, the aerobic bacteria of filler wall can carry out anaerobic metabolism, the gas of generation and exposure because of anoxic
Gas plays certain souring, causes the new biomembrane that regrows after biofilm detachment, and promote the growth of neoformation film.
Biomembrane is at stereochemical structure, strong shock resistance, adaptable to intermittent duty in contact-oxidation pool 7
Line settling tank 6 is based on precipitating, remove the sludge generated in biological treatment process, obtain clear processing water
Syllabus, line settling tank 6 is different from other settling tanks, and effect is first is that cement separates, second is that sludge condensation, and because of water, water
The variation of matter will also temporarily store activated sludge.
Process flow:
Waste water carries out PH adjusting after entering acidification conditioning tank 1 by pipeline, enters back into Fenton's reaction pond 4 and carries out Fenton's reaction,
In Fenton's reaction pond 4 added with 3% hydrogen peroxide and and 10% ferrous sulfate, it is difficult to the organic matter of degradation is oxidized decomposition, later
Into flocculation sedimentation tank 3, organic macromolecule material can be adsorbed added with aluminium polychloride and polyacrylamide in settling tank, in addition
Enter acidizing hydrolyzation tank 5 and contact-oxidation pool 7 afterwards, last waste water enters line settling tank 6 through pipeline, and waste water at this time has reached
National emission standard.
