Polycrystalline silicon industrial wastewater treatment equipment

The invention discloses polycrystalline silicon industrial wastewater treatment equipment, and relates to the technical field of polycrystalline silicon. The polycrystalline silicon industrial wastewater treatment equipment comprises a base, a dirty water tank is movably connected to the top of the base, a water storage tank is further movably connected to the top of the base, a sliding rail is fixedly connected to the outer wall of the base, and an extrusion mechanism is fixedly connected to the outer wall of an electric sliding block. According to the polycrystalline silicon industrial wastewater treatment equipment, a spiral ring is driven by a gear to rotate and contract, a filter plate is extruded through an elastic ring in the contraction process, filter holes in the filter plate are shrunk when the filter plate is extruded, and the shrunk filter holes ensure interception of fine silicon powder and avoid leakage of the fine silicon powder; then a water storage tank is utilized to apply pressure to the w
