摘要
研究发现低强度的超声辐照可以有效促进微生物的活性,可将其用于强化污水的生物处理,通过增强反应器内微生物的活性来提高污水的处理效率.本文综述了超声波在生物工程和生物学上的国内外研究成果,对低强度超声波的生物效应以及在促进生物活性中的主要作用机制进行了探讨,并分析了其在强化污水生物处理中的应用前景.
Low intensity ultrasonic irradiation can improve activity of microorganisms effectively, and thus it can be used to enhance the biological treatment of wastewater and increase the treatment efficiency through improving microbial activity in the biological reactor. The research achievements from home and abroad on the application of ultrasound （US） in bioengineering and biology were comprehensively summarized. The biological effect of low intensity US and the main mechanisms of biological activity enhancement were discussed, and the future application of low intensity US in biological wastewater treatment was analyzed accordingly.
