Improved textile printing and dyeing wastewater treatment device

The invention relates to the technical field of printing and dyeing wastewater treatment, and provides an improved textile printing and dyeing wastewater treatment device which comprises a treatment tank mechanism, a medicine discharging mechanism, a discharging mechanism, a stirring and mixing mechanism, a supporting frame and a rotating support. The upper end of the medicine discharging mechanism is rotationally connected to the upper end of the rotating support, the lower end of the treatment tank mechanism is fixedly connected with a supporting frame, and a discharging mechanism and a stirring and mixing mechanism are arranged in the treatment tank mechanism. A flow control valve at the lower end of a medicine storage tank rotates around the axial direction of the wastewater treatment tank in a reciprocating manner, so that a flocculating agent and a decolorizing agent are more uniformly added into the printing and dyeing wastewater, a stirring and mixing mechanism is driven to rotate through a dischargin
