摘　　要：采用两段超声波结合H_2O_2氧化处理丙烯酸废水。考察了超声波频率、功率、H_2O_2投加量、废水初始pH等对处理效果的影响。一段超声波条件:频率=120 kHz,功率=400 W,H_2O_3投加量为0.7 mL/L,废水pH值为3~5,反应时间为50 min。二段超声波条件:频率=68 kHz,功率=250 W,H_2O_2投加量为0.8 mL/L,调节废水pH值为3~5,反应时间为1 h。经氧化处理丙烯酸废水BOD_5/COD比值(B/C值)由0.28提高至0.47,经生物法降解,实现出水COD<60 mg/L。Two-stage ultrasonic technology combined with H 2 0 2 w a s u s e d f o r a c r y l i c a c i d w a s t e w a t e r t r e a t m e n t .
