Sonophotocatalytic Degradation of Hydrating Polyacrylamide in Wastewater
In consideration of the properties of produced sewage in polymer flooding and the difficulty of its treatment, a new way of the effective degradation of residual hydrating polyacrylamide(HPAM) was put forward. By investigating the sonophotocatalytical degradation of HPAM in aqueous solution, the effects of the different treatment processes of HPAM, the dosage of TiO2, the initial concentration of HPAM and the dosage of H2O2 on sonophotocatalytic degradation of simulated wastewater containing HPAM have studied. The researched results indicated that the degradation rate of HPAM surpassed 97.5% within 120 min under the experimental conditions such as ultrasonic frequency of 42 kHz,output power of 100 W, amount of 600 mg/L TiO2 catalyst and the dosages of 18 mmol/L H2O2, when the initial HPAM concentration of 200 mg/L. It is proved that HPAM removal with the sonophotocatalytic degradation is feasible.
