When the stirring column rotates, the drive box is started, and the deflected impact blocks on both sides of the rotating cross bar are driven by the drive box to rotate, so that the deflected impact blocks intermittently impact the screening plate. When the screening plate is impacted, the lifting slider rises and falls under the limit of the guide cylinder, and the reset springs on the upper and lower sides of the lifting slider are stretched and squeezed respectively, so that the reset spring drives the screening plate to vibrate rapidly when resetting, thereby avoiding impurities from clogging the screening plate, thereby improving the screening efficiency of the screening plate.

[0010] By providing a stirring auxiliary module, when the polluted water in the wastewater treatment cylinder is stirred and mixed, the pump body is started at this time, and the gas is respectively blown into the hollow installation frame and the hollow air blowing frame through the pump body. The air blowing end of the hollow air blowing frame is arc-shaped, so that the gas is evenly blown into the wastewater treatment cylinder. At the same time, the driving motor drives the rotating circular tube to rotate the multiple hollow air blowing rods on the hollow installation frame, so that the hollow air blowing rods simultaneously blow the gas into the wastewater treatment cylinder, so that the gas drives the polluted water to flow fully. When the hollow installation frame rotates, the telescopic springs on both sides thereof use their own elasticity to make the scraper against the inner wall of the wastewater treatment cylinder, thereby scraping off the polluted water attached to the inner wall of the wastewater treatment cylinder, so that the polluted water is fully mixed.
