Degradation of High Saline Wastewater by Ultrasound Irradiation and Fentons Reagent
Wastewater from 1-chlorobutane manufacturing plant contains large amounts of residual 1-chlorobutane and 1-chlorobutane synthesis byproducts, which must be removed before disposal. One of the obstacles to degrade this wastewater is its high salt content, e.g., up to 20％. A combination of ultrasonic and Fenton process (US/Fenton) has been used to treat this wastewater. The results show that the oxidation power of low concentration ion of Fenton could be significantly enhanced by ultrasonic irradiation. The degradation of the saline wastewater by US/Fenton can receive better results compared with either Fenton oxidation or ultrasonic alone. Many operational parameters, such as ultrasonic power density, the temperature, the H2O2 dosage, the Fe2+ dosage, affecting the degradation efficiency were investigated. Under the given test condition, 92.6％ degradation of efficiency was achieved after 3 hours by US/Fenton.
