摘　　要：In order to improve the efficiency of water aerator,based on Venturi experimental principle in hydraulics and fluid dynamic ultrasonic generator,the inlet section,throat section,and outlet section of reed whistle ultrasonic generator were designed,and the effect of the water aerator on dissolved oxygen was preliminarily studied. Results indicate that using this water aerator,the dissolved oxygen was 7. 94 mg / L,exceeding the saturation value of dissolved oxygen( 7. 82 mg / L) at current water temperature,reaching the supersaturation. Therefore,the designed water aerator will have a bright application prospect in sewage treatment,aquaculture and aerated irrigation of plants.In order to improve the efficiency of water aerator,based on Venturi experimental principle in hydraulics and fluid dynamic ultrasonic generator,the inlet section,throat section,and outlet section of reed whistle ultrasonic generator were designed,and the effect of the water aerator on dissolved oxygen was preliminarily studied.
