The pressing plate reciprocates to press bubbles and suspended matter on the top of the wastewater and the alkaline neutralization liquid. The pressing can assist in the rapid sedimentation of foam and suspended matter on the surface of the wastewater, thereby improving the sedimentation efficiency of solid particles in the wastewater, while reducing foam overflow and further avoiding pollution diffusion.

The linkage gear rotates to generate vibration through contact and friction with the U-shaped plate. The vibration of the U-shaped plate drives the separation plate to resonate together. The vibration of the separation plate can effectively improve the separation effect of solid particles in the wastewater, thereby accelerating the solid-liquid separation process and further improving the efficiency of wastewater treatment.
