In-situ photocatalytic treatment equipment and method for micro-polluted water body

The invention relates to the technical field of water pollution treatment, in particular to micro-polluted water in-situ photocatalytic treatment equipment and a method thereof.A plurality of catalytic main bodies are arranged in a photocatalytic box, each catalytic main body is a photocatalytic membrane assembly and comprises a membrane supporting layer, a membrane layer and a photocatalytic layer, and lamp tubes are arranged between the photocatalytic membrane assemblies; oxygen is introduced into the photocatalytic membrane assemblies through the air inlet pipes and seeps outwards from membrane holes of the membrane layers, the seeped oxygen makes contact with a photocatalyst of the photocatalytic layers, then catalytic reaction is carried out under irradiation of the light source assembly, water pollution treatment is achieved, the method is different from an existing conventional aeration means, aeration is prevented from flowing independently of the outside of the catalytic main body, and the aeration e
