Study on Effect of Ultrasonic Oxidation on Pretreatment of Organic Wastewater
By optimizing the factors that affect the degradation efficiency of organic wastewater,such as ultrasound power,solution pH,oxidant type and concentration,reaction time and temperature,the optimal pre-treatment conditions were determined as follows:ultrasound power was 150 W,pH was 6,1%H2O2 was added,pre-treatment reaction time was 25 min,reaction temperature was 50℃.Under above conditions,COD removal rate was stable at around 89%,and other pollutants removal rate was stable at over 80%.
