It is widely used in the advanced treating in later stage.But ozone is used alone, it is low to deposit solubility in water, and model is selected to oxidation operation
The problems such as narrow is enclosed, causes ozone utilization rate low.Reasonable employment catalyst can promote ozone to decomposite oxidability in water more
Strong hydroxyl radical free radical is accelerated, to the oxidation rate of organic matter, greatly to improve ozone utilization rate.
But existing catalytic ozonation tower apparatus has the following problems in production application：
First：The mass transfer effect of ozone and waste water is poor, and ozone utilization rate is low.It is limited by ozone in existing ozone oxidation tower
The Air Bubble Size of generation, air-water contact are not enough, and are lacked efficient mixing wastewater with air mode, are caused ozone utilization rate relatively low.It adopts
It is suitable only for other ways of contact such as pipe-line mixer though jet mixing etc. can improve the dissolved efficiency of ozone to a certain degree
Waste water short stay, mass transfer effect are still restricted.
Second, using catalysis oxidation mode, the selection and filling of catalyst are crucial.Rational catalyst use can promote
The decomposition of ozone in water, accelerates the oxidation rate of organic matter.The common type of feed of catalyst in existing catalysis oxidizing tower
Often it is single random packing under gravity mode, air-water contact is insufficient, and mass transfer effect is poor, and catalyst service life is short, wastewater treatment
It is of high cost.

The reduction building-up work amount and reduction manufacturing cost of big degree；Pass through the cooperation of aerator and backwash water inlet pipe, realization pair
The mixing wastewater with air backwash of catalyst reaches good backwash effect, ensures catalytic activity and the service life of catalyst.
Further, the water-distributing device is water distributor, and the spacing between the Catalytic Layer and water-distributing device is 0.5m；By
There are gaps between Catalytic Layer top and water distributor, and when ozone inversely aeration low from tower, catalyst filling can be in micro- swollen
Swollen state increases mass transfer area preferably with ozone, waste water, improves catalytic efficiency；Simultaneously when catalyst is in backwash,
Catalyst filling is in fully expanded condition, is also conducive to friction between each other, improves the surface removal pollutant efficiency of catalyst；
And catalyst filling can be effectively prevent to run material by water-distributing device, for comparing conventional oxidation tower, it is not necessary that catalyst pressure is arranged
Tight device, structure is more simple, and manufacturing cost is relatively low.
Further, there is the outlet pipe bending segment, the bending segment to have a water outlet, the height of the water outlet
Greater than or equal to the overhead height of the Catalytic Layer；Since the position of water outlet is higher, waste water is not direct under the effect of gravity
Tower body is discharged, drainage speed is slower, and then can effectively improve liquid in the residence time of tower body, ensures that waste water is filled with ozone
The reaction divided.
Further, the height of the water outlet is less than the height of the water inlet pipe；Prevent that water outlet is excessively high and is difficult to out
Water.
Further, the aeration flushing line includes having the aeration tube of multiple fumaroles and being connected with the aeration tube
Gas transmission part；Multiple ventholes are intervally distributed on the bearing plate；The bubble that aeration generates, which fills in the venthole of bearing plate, to be passed through,
With the liter that floats upwards, the water poured in cooperation backwash water inlet pipe carries out air-water backwashing to catalyst together, and flushing effect is good,
Ensure that catalyst has good reactivity.
Further, it is equipped with valve on the water inlet pipe, outlet pipe, backwash water inlet pipe and backwash outlet pipe.
In conclusion the utility model can realize that ozone is contacted with the reverse of waste water in tower body, contact area is big, processing effect
Fruit is good；It is equipped with Catalytic Layer in tower, enhances the oxidation reaction of ozone, improves treatment effect；And the utilization rate of ozone is high, through gas outlet
It is cost-effective without carrying out tail gas destruction after discharge；Change the Inlet Position of ozone directly in traditional ozone oxidation tower
The oxidizing tower of the utility model is obtained, without reconstructing new oxidizing tower, increases reduction building-up work amount and the reduction of degree
Manufacturing cost；By the cooperation of aerator and backwash water inlet pipe, realizes the mixing wastewater with air backwash to catalyst, reach good
Backwash effect, ensure catalytic activity and the service life of catalyst.
