Low pressure mercury lamp, photochemical catalyst and reactor of ultraviolet etc., it is to combine both VUV photodissociation and photocatalysis effect,
When purifying water pollutant, the defects of mass transfer is limited, catalyst and the ozone level of resources utilization be not high be present.
CN103964614A discloses a kind of composite ozone photocatalytic reaction device, and ozone oxidation is mutually tied with photocatalysis treatment technology
Close, waste water by ozone and photocatalysis two-stage high-level oxidation technology are realized in same device.But its defects of existing, has：Pollutant
Contact catalyst occurs light-catalyzed reaction mass transfer and is limited；The presence of ozone reaction room weakens the illumination for reaching photocatalyst surface
Intensity；＜ 260nm length ultraviolets light is nearly free from ozone according to water, and the performance of ozone oxidation pollutant is not reflected.
CN103979666A discloses a kind of integrated ozone photocatalytic reaction device, and the device is anti-including ozone reaction room, photocatalysis
Room and three phase separation room are answered, the device needs supporting ozone generator, high energy consumption.
