The amount of decomposing pollutant is into positive correlation.Photocatalysis equipment in theory can by the use of sunshine produce ultraviolet luminaire as
Light source, but because sunshine is the thin energy, it is difficult to collect utilization, want that reaching heavy industrialization utilizes unlikely, therefore
Industrially want that using photocatalysis Decomposition pollutant artificial light source should be selected.Photocatalysis equipment is all Theoretical Design at this stage, practical
Type does not have substantially, and it is all that, with large surface as general character, some equipment can reach very well in theory that the photocatalysis hair of test-type answers device
Effect, but be extremely difficult to expected effects in the sewage disposal of actual complex.After the nineties in 20th century, catalyst photocatalysis
Because possessing self-cleaning, antifog and disinfection effect, start to move towards our life.The photocatalysis of catalyst is a kind of energy
The high-level oxidation technology of efficient process organic pollution, small toxicity can be also effectively converted into poisonous heavy metal Hg, cadmium etc.
Even harmless state.There is the hydroxyl radical free radical of photocatalysis generation strong oxidation performance to decompose nearly all organic matter into CO2With
H2O, ammonia nitrogen can also be broken down into nitrate anion (NO3 -).The cost of its process is simple, early investment and later stage operation maintenance is not
It is high.And photocatalysis need not add other medicines, as long as thering is sunshine or the artificial ultraviolet light just to play a role, be it is a kind of not
The environment-friendly materials of secondary pollution can be produced.Therefore in the advanced treating of waste water, photocatalysis has very big performance space.
In actual applications, encountering some problems needs to solve.These problems are related to each of multiphase photocatalysis reactor
Individual aspect, wherein, the problem of the existence of catalyst, the geometry of reactor and size and photosystem this three aspect is particularly
Concentrate.Such as " photocatalytic oxidation reactor (the patent No. forever high：CN201357069Y), catalyst and waste water are mixed into stabilization
Suspended state, but have the shortcomings that catalyst be easy to passivation.Zhang Xiaoping et al. design " a kind of gas-solid fluidized bed photocatalytic sets
Standby (the patent No.：CN1623645A), using annular gas-solid fluidized bed reactor, there is absorption and scattering of the reaction medium to light
Cause the such problem of deficiency of light energy.Other similar photocatalysis equipment, have that reaction rate is slow, running expense is held high mostly
The problems such as expensive, complex operation.
The content of the invention
Because short wavelength ultraviolet irradiation air can produce certain density ozone, enter together after ozone and air mixing
Sewage conduct, pressurized tank is entered together with sewage through turbulence pump；The sewage in pressurized tank flows into medium wavelength ultraviolet reactor simultaneously
In, there is light-catalyzed reaction, ozone also reacts in the presence of medium wavelength ultraviolet, generates hydroxyl radical free radical and photocatalysis
Collaboration treatment sewage.
According to above-mentioned principle, it is an object of the invention to provide a kind of multistage photocatalysis advanced waste treatment apparatus, can be effective
Ground treatment waste water, makes up to relevant emission standards.
A kind of multistage photocatalysis advanced waste treatment apparatus, the bottom of device is provided with sewage pipe, is set on the sewage pipe
Three-way control valve is equipped with, a mouth of pipe of the three-way control valve is connected to appendix, and another mouth of pipe is connected to turbulence pump；Institute
The other end for stating appendix is connected to ozone generator, and the side of the ozone generator is connected by pipeline with air blower；Institute
The side for stating turbulence pump is provided with pressurized tank；The pressurized tank is connected by pipeline with photo catalysis reactor.
Further, the three-way control valve is converging valve, and liquid is closed from appendix from sewage pipe and ozone through converging valve
Stream, so as to flow into turbulence pump.
Further, the ozone generator, is provided with screw type sewage routeway between its shell and quartz burner.
Further, the pressurized tank can automatically adjust turnover stream by pressure-sensitive switch.
Further, the photo catalysis reactor, using the cylindrical reactor of plated surface catalyst film.
Further, the photo catalysis reactor is using medium wavelength uviol lamp as light source.
Beneficial effect：
1. catalyst does not need medicament for photocatalysis technique, as long as thering is sunshine or the artificial ultraviolet light just to play a role,
Do not produce sludge not result in secondary pollution yet, be entirely a kind of environmentally friendly processing mode.
2. catalyst is there is noxious pollutant during photocatalysis can decompose environment using its own characteristic, poisonous
Heavy metal Hg, cadmium etc. can also be effectively converted into the even harmless material of small toxicity, and photocatalysis has self-cleaning, antifog and sterilization to kill
The effect of bacterium.
3. catalyst photocatalysis apparatus and process is simple, and the cost of early investment and later stage operation maintenance is not high.
