The side of dispersion fiber 1 in ultrafiltration membrane filaments 3 sends ultraviolet light, excites the titanium dioxide in strong brine, is allowed to that electron transition occurs,
Electronics-hole pair and OH free radicals are produced, after they are contacted with organic pollution, pollutant exhaustive oxidation is degraded into CO2
And H2O.Meanwhile open air inlet 11, blast air/oxygen into putamina 2, promote the progress of light-catalyzed reaction, make gas and
Liquid mixes uniformly, improves oxidation efficiency.High strong brine after hollow fiber ultrafiltration film wire 3 is separated by filtration removing COD is through production
The mouth of a river 10 is discharged, and titania powder is then trapped in hollow fiber ultrafiltration film wire 3.When disengaging differential water pressures reach 2 kilograms, stop
Only intake, start backwash procedure, open lower row's mouth 13, discharge concentrate, backwash water inlet 12 and air inlet 11 are opened, to hollow
Ultrafiltration membrane filaments 3 fully rinse and clean, and the concentrate containing titania powder and backwash water of discharge enter titanium dioxide
Dosing system 14 reuses, after accumulation is failed using a period of time, the concentrate containing titania powder of discharge and backwash
Water is then introduced into titanium dioxide regenerative system 15, and entering back into titanium dioxide dosing system 14 after regeneration reuses.
Because the diameter of hollow fiber ultrafiltration film wire 3 is very small, so after water enters hollow fiber ultrafiltration film wire 3, can be maximized
Segmentation, organic matter and titania powder in every hollow fiber ultrafiltration film wire 3 in water send ultraviolet with the side of dispersion fiber 1
Light maximumlly can be contacted fully, so that photocatalytic oxidation efficiency is high.
It should be noted that above-described embodiment does not limit the utility model in any form, it is all to use equivalent substitution or wait
The technical scheme that the mode of effect conversion is obtained, all falls within the scope of protection of the utility model.
