| 英文摘要: |
| Intensity of cavitation is significant in ultrasonic wastewater treatment, but is complicated to measure. A time difference based method of ultrasonic cavitation measurement is proposed. The time differences at different powers of 495kHz ultrasonic are measured in experiment in comparison with conductimetric method. Simulation results show that time difference and electrical conductivity are both approximately positive proportional to the ultrasonic power. The degradation of PNP solution verifies the availability in wastewater treatment by using ultrasonic. |
