The bubble generator was used to generate microbubble water to simulate the reinjection water containing micro-bubbles.The microbubble contents of tap water,the prepared micro-bubble-containing water and ultrasonically treated water with micro-bubbles were explored through measurements and char-acterization of turbidity,electrical conductivity and dissolved oxygen.The effect of ultrasonic treatment on the contents of microbubbles in the sample water was studied through the characterization and analysis of the microbubbles in the liquid samples before and after the elimination of micro-bubbles by ultrasound.The results show that the ultrasonic cavitation helps to accelerate the growth and coalescence of microbub-bles.There is an energy transfer process during ultrasonication,which reduces the gas content in the treated water by providing energy and promotes the elimination of microbubbles.The present research lay a foundation for the ultrasonic microbubble removal technology to be used in the efficient reinjection of geothermal water.
