Description
Technical field
The utility model belongs to environmental protection technical field, particularly water-treatment technology field, relates to a kind of air lift circulation ozone catalytic oxidation reaction device and advanced treatment method for sewage water.
Technical background
Along with Economic development, the mankind are more and more serious to the pollution of water, more and more higher to the requirement of Water warfare, sewage disposal and regeneration effluent.Putting before this, Novel sewage treatment technology and method also more and more seem heavy to pass, especially the treatment technology of difficult degradation sewage and and advanced treatment of wastewater technology.
Advanced treatment of wastewater refers to and processes further to realize lowering disposal of pollutants or reaching subsequent regeneration processing requirement to the sewage through traditional wastewater process.
Industrial sewage or industry and municipal combined sewage be usually difficult to reach emission standard through traditional sewage water treatment method, have larger pollution to environment.In order to lower pollution, advanced treatment of wastewater should be carried out to this kind of water.
The recycle of water will be one of the most important approach of water-deficient area sustainable economic development.Regeneration effluent gordian technique is membrane technique, and advanced treatment of wastewater is bridge necessary between traditional wastewater process and membrane technique.
But particularly always have some to be difficult to biological degradation in industrial sewage in sewage, or even to the virose pollutent of microflora.These pollutents can pass through chemical reaction, make it sex change and become bio-degradable.
Ozone can oxidize majority organism, can directly reduce contamination index's chemical oxygen demand (COD), but efficiency is lower by ozone oxidation.Can be changed the biochemical characteristic of hardly degraded organic substance by ozone oxidation, then by biochemical method by contaminant degradation, such efficiency is higher.Ozone oxidation efficiency can be improved by the method for adding ozone oxidation catalyst.
But the reaction of ozone and water pollutant relates to the competition that ozone solution and ozone are overflowed, how the competition of ozone reaction and ozone decomposed, therefore improve the dissolving of ozone and be the key improving ozone efficiency with fully contacting of solid-phase catalyst.The method increasing solid-phase catalyst, processed sewage and ozone gas three and contact is lacked in known technology.
Summary of the invention
The utility model will solve the technical problem that in known technology, ozone reaction efficiency is lower, disclose a kind of utilize air lift circulate by catalyst fluidization and change liquids and gases flow to air lift circulation ozone catalytic oxidation reaction device.
In order to realize above object, this air lift circulation ozone catalytic oxidation reaction device comprises a reaction tank, at least one ozone micro porous aeration head being positioned at the air lift circulation tube bottom reaction tank and being positioned at bottom each air lift circulation tube; Open bottom described air lift circulation tube, top seal is cut side, top and is provided with multiple pod apertures; Catalyzer water conservancy diversion skewed slot is provided with bottom described reaction tank; Described reaction tank top is provided with exhaust port, maintenance manhole and water outlet, and bottom is provided with water inlet and ozone gas pipeline.
Also fluidized-bed catalyst is comprised in described catalytic ozonation reaction unit.
Fluidized-bed catalyst is added reaction tank when using by the utility model air lift circulation ozone catalytic oxidation reaction device, processed sewage is injected reaction tank through water inlet, then by the gas containing ozone by ozone gas pipeline and at least one micro porous aeration head expose to the sun bottom at least one air lift circulation tube into; In reaction tank, catalyzer, water and gas are subject to gas stripping fast to upper reaches in air lift circulation tube inside, pod apertures water conservancy diversion through being located at gas circulating tube upper side turns to, major part water-band moves micro-bubble to dirty, catalyzer moves downward simultaneously, water again enters thrust-augmenting nozzle and upwards flows bottom air lift thrust-augmenting nozzle, realizes air lift circulation; Bottom catalyst sedimentation to reaction tank, the catalyzer water conservancy diversion skewed slot be located at bottom reaction tank flows to bottom air lift circulation tube, again enters gas circulating tube and to upper reaches, realize iterative cycles under the effect of air lift cycling stream; Air pocket is up gradually, discharges through exhaust port; Small part flows through to upper reaches after the water of pod apertures, and continues to react with residue ozone, finally discharges through water outlet.
The beneficial effect of air lift circulation ozone catalytic oxidation reaction device shows that sewage and catalyzer are under the effect of gas circulation stream, inner to upper reaches at air lift circulation tube, at air lift circulation tube externally to dirty, and iterative cycles.Under current drive, micro-bubble is at air lift circulation tube externally to dirty, extends the residence time of micro-bubble.Momentum containing ozone gas is used to produce air lift cycling stream, achieves sewage, catalyzer contacts repeatedly with micro-bubble inside and outside air lift circulation tube, improves the efficiency of catalytic ozonation reaction.Hardly degraded organic substance in processed sewage is by ozone oxidation, and the chemical oxygen demand (COD) of sewage is reduced, and the biodegradability of organic matter after oxidation is improved.
