[0031] Such as figure 1 As shown, the treatment method for removing zinc in electroplating wastewater, the electroplating wastewater containing zinc ions enters the collection well 1 through the wastewater pipeline, where centralized collection and preliminary stabilization are performed, and the outlet of the collection well 1 is connected to the coarse grid 2 through the wastewater pipeline. The large-diameter solid matter in the waste water is removed here, the outlet of the coarse grid 2 is connected to the primary sedimentation tank 3 through the waste water pipeline, and the insoluble matter in the waste water is further removed here, and the outlet of the primary sedimentation tank 3 is connected to the pH value adjustment tank through the waste water pipeline 4. The pH value of wastewater is accurately adjusted here. The pH value of the effluent of the pH value adjustment pool 4 ranges from 5.5 to 6.5 to meet the requirements of the inlet water pH value of the metal spher...
