摘要
采用超声波-Fenton高级氧化工艺联合降解百草枯模拟农药废水,研究了超声-Fenton耦合处理过程中各因素对百草枯溶液COD去除率的影响.结果表明:将百草枯原溶液稀释150倍时,在超声波频率为19 kHz,功率为200 W,超声时间为150 min,H_2O_2加入量为40 mmol,[H_2O_2]与[Fe^(2+)]的物质的量比比例为5时,百草枯废水COD去除效率可达95.1%.
The process of ultrasonic coupling Fenton oxidation was used for dealing with paraquat simulated pesticide wastewater. The effects of reaction conditions on the COD removal rate were investigated. The results showed that the COD removing rate of paraquat wastewater reaches up to 95.1% after 150 min reaction under the experimental conditions ： ultrasonic frequency of 19 kHz, power of 200 W, pH 3.5, amount of 40 mmol H2O2 and [ H2O2 ] / [ Fe2＋] of 5.
