Research on degradation of dye industry wastewater by ultrasonic-Fenton process
超声-Fenton高级氧化降解染料工业废水的研究

The laboratory scale treatment of dye industry wastewater by ultrasound wave coupling Fenton process was studied. The effects of the process' s factors (wastewater concentration, pH, reaction time, frequency and power of supersonic, amount of H_2O_2 and FeSO_4) were also investigated. The COD removal rate of dyes wastewater surpassed 91.8 % after 150 min reaction under the experimental conditions:ultrasonic frequency of 45 kHz , output power of 200 W, pH of 2.63, amount of 60 mmol/L H_2O_2 and 12 mmol/L FeSO_4, and room temperature.
