AI Technical Summary
Existing wastewater treatment filtration devices have low filtration efficiency and slow filtration speed, and pollutants and impurities easily accumulate on the filter screen, leading to clogging.
The system combines a conical filter screen with an impurity tube, uses a pressurizing component to pressurize and filter wastewater, and performs backwashing when the flow rate sensor detects blockage, automatically cleaning the filter screen.
It improves filtration efficiency, prevents impurity buildup, enables automatic cleaning of the filter screen, and enhances the practicality of the device.
