It is low.Suspended state catalyst distribution is uniform, and surface area is larger, and the higher but tiny photochemical catalyst particulate of catalytic efficiency is not easy as tradition
Isolation technics separation and recovery, recycling rate of waterused is low, and discharge liquor is also easy to produce secondary pollution, seriously limits its application.
Membrane separation technique is a kind of new isolation of purified technology developed rapidly in recent years.In water treatment procedure,
Acted on by the microporous entrapment on film surface and separate the purpose for concentrating water pollutant to reach, typically without phase transformation in membrane separating process
And secondary pollution, it can at normal temperatures operate continuously, have that energy consumption is low, equipment volume is small, the advantage such as easy to operate.However, film is dirty
Dye problem causes flux depression, and shortens the service life of film, although control fouling membrane measure achieves certain research and entered
Exhibition, but still be the main bottleneck of membrane separation technique development.
Photocatalysis oxidation technique and membrane separation technique have respective advantage, but there is also respective deficiency, in water process row
Industry is less by the case of the two connected applications, and photocatalysis-membrane separation technique is ripe not enough.Therefore, prior art needs
Improve and develop.
