Abstract

The invention discloses a double-film photocatalytic reactor for wastewater treatment. The double-film photocatalytic reactor for the wastewater treatment comprises a feed liquid tank (1), a first group of a film or a film component (2), a second group of a film or a film component (8), a first vacuum pressure gauge (3) and a second vacuum pressure gauge (11), a first pump (4) and a second pump (12), a photocatalyst (5), a light source (7), a quartz sleeve (6), a reaction tank (9), a stirrer (10), and a penetrating fluid tank (13). The reactor comprises two films or film components, the firstgroup of the film or the film component is placed in the feed liquid tank, and the second group of the film or the film component is placed in the reaction tank. The first group of the film or the film component is used for intercepting suspended particles and insoluble solid in water solution, and eliminating the influence of the suspended particles and insoluble solid to the photocatalytic activity of a catalyst. The second group of the film or the film component is used for separating the photocatalyst and treating fluid. The double-film photocatalytic reactor is suitable for practical complicated photocatalysis treatment of the wastewater.

Description

technical field [0001] The invention relates to a double-membrane photocatalytic reactor used for wastewater treatment, belonging to the technical field of wastewater treatment. Background technique [0002] Photocatalytic water treatment technology has the characteristics of high efficiency, energy saving and environmental protection, and has broad application prospects. Membrane photocatalytic reactor combines the characteristics of membrane separation technology and photocatalysis technology. On the one hand, it can solve the problem of separation of photocatalyst and treatment liquid. On the other hand, it can improve the catalytic effect of photocatalyst. Promote the application of photocatalytic technology and membrane separation technology in the field of wastewater treatment. Chinese patent CN204529551U discloses a reactor combined with photocatalysis and membrane separation, which has a good treatment effect on washing wastewater. There are also many reports on va...
