[0012] The beneficial effects of this utility model are:
[0013] When the propulsion unit drives the stainless steel impeller to rotate at high speed, it creates a negative pressure in the water. Under this negative pressure, air is drawn into the filter screen through the air inlet pipe. The drawn-in air is sheared into many tiny bubbles. As these bubbles rise, they mix the water. Through forced mixing and oxygenation, oxygen from the air is forcibly delivered into the wastewater, increasing the dissolved oxygen concentration and promoting microbial metabolic activity. This accelerates the decomposition and degradation of organic matter, improves wastewater treatment efficiency, eliminates the need for additional mixing equipment, and thus reduces costs.
