| Abstract: | 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. |
| |
| Keywords: | low intensity ultrasound wastewater treatment enhanced biological activity biological effect |
