Semiconductor production wastewater purification treatment device and method thereof

The invention belongs to the technical field of wastewater purification, and particularly relates to a semiconductor production wastewater purification treatment device and method. A pair of symmetrically distributed inflatable floating plates is connected between the side walls in the tank body in a sliding manner; the top of the pool body is fixedly connected with a pair of placing boxes which are symmetrically distributed; the inner bottom wall of the placing box is provided with a pair of square through grooves which are symmetrically distributed; the groove wall of the square through groove is slidably connected with a rack. One end of the rack is fixedly connected to the side wall of the inflatable floating plate; rotating rods are fixedly connected to the side walls of the two sides of the placement box; a semi-ring gear is arranged at the end, away from the containing box, of the rotating rod. A discharging opening is formed in the bottom of the placing box; a semi-ring gear can be driven to open a di
