Study on SBR Enhanced by Low Intensity Ultrasound for Treatment of Chemical Production Wastewater

Abstract:

In this paper, activated sludge process enhanced by ultrasound was applied to treat the chemical production wastewater containing nitroaromatic compound after ultrasonic pretreatment. The factors influence to treatment effect such as ultrasound power and frequency, irradiation time were investigated by experiment. The mechanism of ultrasound enhanced activated sludge process was analyzed. The experimental results show that ultrasonic irradiation with appropriate parameters can effectively enhance sludge activity, improve the treatment efficiency. The optimal treatment conditions are as follows: ultrasound power 10W, frequency 25kHz, irradiation time 15min.
