摘要
采用超声-Fenton氧化联用处理印染废水,并将超声-Fenton氧化联用与两种方法单独作用对废水的处理效果进行了对比。考察了初始pH、Fe2+、H2O2投加量和反应时间对印染废水的处理效果。结果表明,对于CODCr浓度为1 000mg/L的印染废水,超声-Fenton氧化联合处理在pH为4,Fe2+投加量为0.02mol/L,H2O2投加量为0.18mol/L,反应时间6min,CODCr的去除率达到最高61.05%。
The combination of Ultrasonic with Fenton oxidation is used to treat dyeing wastewater and compared with the two meth- ods alone for wastewater treatment. The effects of the initial pH value, Fe^2＋ and H202 dosage, and the reaction time on dyeing wastewater treatment are investigated. The results show that, for the dyeing wastewater with CODcr concentration of 1 000 mg/L, when the initial pH is 4, Fe^2＋ dosage is 0. 02 mol/L, H202 dosage is 0. 18 mol/L, and the reaction time is 6 min, the CODcr removal rate can reach the highest value 61.05%.
