The device is characterized by comprising a suspended photo-catalytic reaction device (1) and an inorganic ceramic membrane separation device (2), wherein upper ends of the suspended photo-catalytic reaction device (1) and the inorganic ceramic membrane separation device (2) are connected with each other by using a pipe (4); and a high pressure diaphragm pump (3) is connected between lower ends of the suspended photo-catalytic reaction device (1) and the inorganic ceramic membrane separation device (2); integrated operation of the photocatalytic oxidation and the inorganic ceramic membrane separation can be realized so as to overcome the defect that photocatalyst is hard to be separated and recycled in a suspended photo-catalytic reactor.

Description

technical field [0001] The invention belongs to the field of photocatalytic advanced oxidation technology and related equipment for solving photocatalyst separation and recovery, and relates to a device for separating and coupling photocatalytic oxidation and inorganic ceramic membrane. Background technique [0002] Since the 1970s, Japanese scientists discovered the semiconductor photocatalyst TiO 2 Since photoelectrochemistry can split water, photocatalytic technology has attracted extensive attention of researchers from all over the world. This technology is not only committed to decomposing water to obtain hydrogen energy, and realizes the conversion of solar energy to hydrogen energy, the "holy grail" in photocatalytic technology, but also has more practical photocatalytic technologies in self-cleaning, air purification, sterilization, wastewater treatment, etc. The field has been vigorously developed and utilized. As a new advanced oxidation technology, photocatalyt...
