Description
Technical field
The present invention relates to a kind of refinery sewage water treatment methods, relate more specifically to a kind of refinery sewage of recyclable catalyst
O3 catalytic oxidation processing method.
Background technique
With the in poor quality of petroleum resources, the sewage quality that Petrochemical Enterprises generate worse and worse, while environmental emission standard
But more stringent, cause Petrochemical Enterprises sewage treatment difficulty to increase.Most original sewage disposal systems of Petrochemical Enterprises cannot
It meets environmental requirements, carries out proposing mark transformation.
A/O system is that the effective means of removal pollutant is thrown in anoxic pond to improve the treatment effect of A/O system
Add a certain amount of Powdered Activated Carbon, utilizes the organic matter in the good adsorption properties removal sewage of Active Carbon in Organic.Pass through
Wet oxidation process regenerates the active carbon sludge that secondary settling tank is discharged, and removes the organic matter adsorbed in active carbon, makes active carbon
Restore adsorption capacity, recycling utilizes again, has not only improved the treatment effect of A/O system, but also reduce the dosage of active carbon, this is just
It is PACT-WAR (Powdered Activated Carbon-wet type air regeneration) technique.
Also containing the organic matter of difficult for biological degradation in the sewage handled by A/O system, these pollutants can be by urging
Change ozone oxidation mode to remove.O3 catalytic oxidation method is decomposed organic using the strong oxidizing property hydroxyl radical free radical that catalysis ozone generates
Object, the ammonia nitrogen that can be effectively removed in sewage reduce COD of sewage and TOC.
Active carbon can catalysis ozone generate hydroxyl radical free radical, can be used as O3 catalytic oxidation catalyst use (still can
It builds, chemical industry environmental protection, 2012,32 (5): 405-408).Chinese invention patent CN201010273694.8 discloses a kind of utilization
The activated-carbon catalyst of excess sludge of municipal sewage plant preparation, the trace drug in O3 catalytic oxidation water can reach
99% or more removal rate.It includes Activated Carbon Catalytic Ozonation Process and life that Chinese invention patent CN03123392.9, which is disclosed a kind of,
The water treatment technology of two units of object active carbon.Another Chinese invention patent CN201310088861.5, which is disclosed, utilizes activity
The method that charcoal O3 catalytic oxidation handles coking wastewater can put into reactor by separation with the active carbon of water outlet outflow again
In, coking wastewater COD removal rate is up to 60% or more, and volatile phenol removal rate is up to 90% or more.
Active carbon is also used as carrier loaded transition metal element, and the catalyst as O3 catalytic oxidation uses.Have
Research be also shown that active carbon is also advantageous over Al as carrier2O3And SiO2Carrier (Zhou Yunrui etc., Tsinghua University's journal (natural section
Learn version), 2007,47 (9): 1481-1484).Chinese patent CN200910032210.8 discloses a kind of activated carbon supported copper
Catalyst ozone oxidation landfill leachate, for COD removal rate up to 80% or more, ammonia nitrogen removal frank is up to 97.5% or more.In
State's patent of invention 201310085997.0 discloses a kind of deep using active carbon particle carried metal compound for catalysis ozone oxidation
The preparation method of degree processing coal chemical industrial waste water.Chinese invention patent CN201210178342.3 disclose it is a kind of load have copper, iron,
The activated-carbon catalyst of manganese, molybdenum nickel compound suspends and constitutes heterogeneous catalytic oxidation system in the reactor, can significantly cut down
Bio-toxicity, organic pollutant and the coloration of waste water.
After activated-carbon catalyst is used for a long time, surface chemical property can change, and absorption property reduces, and cause to urge
Change activity reduce, it is therefore desirable to periodically it is carried out regeneration treatment (Liu Zhenggan etc., Chinese water supply and drainage, 2010,26 (4): 6-9,
14).But there is presently no the regenerated relevant reports of activated-carbon catalyst.
The active regenerated device of charcoal WAR in PACT-WAR technique, under high-temperature and high-pressure conditions, which can will be superfluous
Biological sludge destroy and the polluter that adsorbs in magnesium oxide/absorbent charcoal, thus regenerating waste active carbon, and recycle and reuse.
WAR regeneration can be put into A/O again and be recycled with the adsorption capacity of activity recovery charcoal, and activated-carbon catalyst is regenerated by WAR
It can restore catalytic performance, therefore regenerate and can subtract using activated-carbon catalyst of the PACT-WAR system to O3 catalytic oxidation
Few investment and operating cost.
