超声辅助脱除水中的微气泡

摘要利用气泡发生仪产生微气泡水,模拟含气泡的回灌地热水。通过浊度、电导率、溶氧量等参数测量和表征自来水、微气泡水和超声处理水的微气泡含量。通过对模拟微气泡水等样品中微气泡在超声消泡前后的含量等表征和分析,研究了超声处理对样本水体中微气泡含量的影响。结果表明,超声处理时由于超声空化作用,有助于加快微气泡成长、聚并;超声作用过程也是能量传递过程,通过提供能量降低水中气体含量,促进了微气泡的脱除。研究对于超声微气泡脱除技术用于地热水高效回灌奠定了基础。

Abstract： 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 characterization 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 microbubbles. 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.
