AI Technical Summary
Existing wastewater treatment separation devices suffer from problems such as high filter pressure, easy clogging, and short service life due to single-stage filtration.
A multi-stage separation device is adopted, which uses stepped baffles and filter belts for step-by-step filtration. The filter belt is rotated by a motor-driven shaft to remove impurities, and a brush roller is used to wash the filter belt.
This effectively avoids clogging of single-stage filters, extends the service life of filters, and ensures filtration efficiency and smooth operation of the equipment.
