Studies on treatment of pharmaceutical wastewater containing nitrobenzene by dual-frenquercy ultrasonic/ozone
|
Abstract:
In this study,ozone,single-frenquercy ultrasonic/ozone and dual-frenquercy ultrasonic/ozone were applied to treat the pharmaceutical wastewater containing nitrobenzene.The influencing factors to the treatment effect,such as the wastewater initial pH value,the ozone inflow,the frequency and power of ultrasonic,were investigated by experiments to determine the optimal conditions of the treatment by dual-frenquercy ultrasonic/ozone.The indexes of the effluent can reach the first criteria specified in Integrate...
