Description
Technical field
By catalytic ozonation the tail gas generated after sewage treatment is recycled the utility model relates to a kind of
Device belongs to catalytic ozonation system tail-gas recycling device.
Background technique
Catalytic ozonation system can be used for the processing of organic wastewater, but generally existing ozone during disposing waste water
The low problem of utilization rate, reaction is not discharged the ozone being passed through completely.
Currently, the vent gas treatment of catalytic ozonation system, what is generallyd use is after the pernicious gas in tail gas is degraded
It is discharged into atmosphere, unreacted ozone can also be discharged into atmosphere, cause the waste of ozone.
And the sewage after biochemical treatment, the indexs such as coloration, stink, COD, ammonia nitrogen all have been lowered to a certain degree,
But further advanced treating is also needed, processing cost is increased.
Summary of the invention
The utility model provides a kind of knot for deficiency existing for tail gas disposal technique in existing catalytic ozonation system
Structure is simple, makes the recycling of tail gas after the catalytic ozonation processing that unreacted ozone is fully used and recycle in tail gas
Device.
The reuse means of tail gas after the catalytic ozonation processing of the utility model, using following technical scheme.
The device, including treating column, air-introduced machine, aeration plate and sewage spray equipment；The top for the treatment of column is provided with sewage
Inlet pipe and exhaust pipe are provided with aeration plate and sewage spray equipment in treating column, and the lower part for the treatment of column, sewage is arranged in aeration plate
Spray equipment is arranged in the top for the treatment of column and is located at the lower section of exhaust pipe, and sewage spray equipment is connect with sewage inlet pipe, handles
The bottom of tower is provided with tail gas inlet pipe, and air-introduced machine is connected on tail gas inlet pipe, and tail gas inlet pipe is protruded into treating column and connect with aeration plate.
The sewage spray equipment includes spray tube and spray head, and spray tube is horizontally disposed and connect with sewage inlet pipe, is sprayed
Leaching is distributed on spray tube upside down.
Catalytic ozonation system carries out treated tail gas to organic wastewater and is sent into sewage treatment tower by air-introduced machine, passes through
Aeration plate realizes gas distribution.Sewage after biochemical treatment from the top for the treatment of column spray and under, in treating column and from bottom to top
Tail gas is come into full contact with.Tail gas is run from bottom to top, and by the discharge of processing top, sewage from top to bottom, is arranged by processing tower bottom
Out, sewage is not stored in whole process treating column.
The utility model has the characteristics that structure simple operation is convenient, and by catalytic ozonation system, treated that tail gas draws
Enter sewage treatment, on the one hand make full use of unreacted ozone, depth on the other hand is carried out to the sewage after biochemical treatment
Processing, can further decrease its coloration and stink, while COD, ammonia nitrogen value also have corresponding reduction.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the reuse means of tail gas after the utility model catalytic ozonation is handled.
Wherein: 1. sewage inlet pipes, 2. treating columns, 3. exhaust pipes, 4. spray heads, 5. aeration plates, 6. drainpipes, 7. tail gas into
Pipe, 8. air-introduced machines, 9. spray tubes.
Specific embodiment
The utility model catalytic ozonation processing after tail gas reuse means as shown in Figure 1, include treating column 2,
Air-introduced machine 8, aeration plate 5 and sewage spray equipment.
The top for the treatment of column 2 is provided with sewage inlet pipe 1 and exhaust pipe 3.Aeration plate 5 and sewage spray are provided in treating column 2
The lower part for the treatment of column 2 is arranged in shower device, aeration plate 5.Sewage spray equipment is arranged in the top for the treatment of column and is located at exhaust pipe 3
Lower section, sewage spray equipment includes spray tube 9 and spray head 4, and spray tube 9 is horizontally disposed and connect with sewage inlet pipe 1, spray
First 4 are distributed in downward on spray tube 9.The bottom for the treatment of column 2 is provided with tail gas inlet pipe 7, connects air-introduced machine 8, tail on tail gas inlet pipe 7
Gas inlet pipe 7 is protruded into treating column 2 and is connect with aeration plate 5.
By biochemical system treated sewage, coloration is 20~50 (degree), and stink grade is 2 grades of (NH30.5ppm,
H2S0.005ppm), COD is 100~400mg/L, and ammonia nitrogen is 50~100mg/L.Catalytic ozonation system to organic wastewater into
Treated that exhaust gas forms tail gas after overpickling, alkali cleaning, UV photodissociation for row, removes ozone concentration in tail gas in 50~200ppm
Contain CO, CO2Outside, without containing other impurities gas (if containing H2S、NH3Equal escaping gas need further to vent gas treatment,
To prevent the foreign gas contained in tail gas from entering subsequent sewage to be treated).Tail gas is by air-introduced machine with 600m3The air quantity of/h
Sewage treatment tower 2 is sent by bottom, gas distribution is realized by aeration plate 5.
Under sewage after biochemical treatment is sprayed from the top spray head 4 for the treatment of column 2, in treating column 2 with tail from bottom to top
Gas is come into full contact with, and carries out advanced treating to the sewage after biochemical treatment.Tail gas is run from bottom to top, by processing top row
Out, sewage from top to bottom, is discharged by the bottom for the treatment of column 2, does not store sewage in whole process treating column 2.
Embodiment is given below:
Catalytic ozonation tail gas after integrated treatment, ozone content: 150ppm
Sewage index after biochemical treatment: coloration 45；Stink grade is 2 grades of (NH30.5ppm, H2S 0.005ppm)；
COD is 210mg/L；Ammonia nitrogen is 89mg/L.
Sewage index after the device ozone advanced treating of the utility model: coloration 8；Stink grade is 1 grade of (NH3
0.05ppm, H2S is not detected)；COD is 73mg/L；Ammonia nitrogen is 32mg/L.
