Photoelectrocatalysis water purification treatment device

The invention discloses a photoelectrocatalysis water purification treatment device, which belongs to the technical field of water treatment, and has the technical key points that the photoelectrocatalysis water purification treatment device comprises an overturning unit which is connected in a treatment box in a sliding manner and is respectively connected with a photoelectric cathode and a photoelectric anode; the sensing unit is mounted on the treatment box; the sliding unit is rotationally connected to the treatment box; and the rotating unit is rotationally connected into the treatment box. When water is purified, water is guided into the treatment box through the water inlet valve, and an additive can be added into the treatment box at the same time, so that the water purification effect is improved. When the induction unit is illuminated, the induction unit can be heated to expand, so that the induction unit can drive the sliding unit to slide by being connected with the rotating unit, and the sliding
