AI Technical Summary
When treating oily wastewater, existing aeration discs cause membrane pores to enlarge due to prolonged aeration, leading to wastewater entering and damaging the pipes, and oil clogging the pores, resulting in high cleaning and maintenance costs.
An aeration device for treating oily wastewater was designed. It uses an inverted conical air outlet pipe to form a vortex, and is equipped with an expansion mechanism and a cleaning section. A rotating scraper is used to clean the membrane, and a sealing mechanism is combined to prevent wastewater backflow, thereby extending the gas-liquid contact time and cleaning the pores.
It prolongs the contact time between bubbles and liquid, prevents pore blockage, reduces cleaning and maintenance costs, and avoids pipeline damage.
