Abstract: The present application discloses a conductive membrane and a preparation method thereof, which belong to the field of membrane separation technology. The conductive membrane provided by the present application includes a porous base layer film, a porous intermediate layer film, and a porous conductive layer film which are disposed layer by layer in sequence; wherein at least some holes of the base layer film are communicated with holes of the conductive layer film through holes of the intermediate layer film, and material of the intermediate layer film is the same as material of the base layer film and of the conductive layer film. Regarding the conductive membrane provided by the present application, it can be coupled with electrochemical technology, so that the membrane exhibits new excellent properties at the same time of playing separating characteristic.

Abstract: The disclosure provides an ozone contact tank, which includes a water inlet gallery (1), an aeration gallery (2), a water distribution zone (3), a reaction zone (4) and a water outlet trough (5) which are disposed according to the intake order and are communicated in sequence; the top of the water inlet gallery (1) is communicated with the top of the aeration gallery (2); the bottom of the aeration gallery (2) is communicated with a water inlet end of the water distribution zone (3) via a narrow passage (6); the top of the water distribution zone (3) is communicated with the bottom of the reaction zone (4) via a perforated plate (41); the top of the reaction zone (4) is communicated with the water outlet trough (5). The disclosure also provides an ozone contact method using the ozone contact tank, which can greatly improve the disinfection effect.
