水力空化联合Fenton降解双酚A的性能研究
|
摘要
为探究水力空化(HC)联合Fenton(HC-Fenton)对双酚A(BPA)的降解效果,探讨了入口压力、溶液pH、Fe~(2+)和H_2O_2含量等操作条件对其降解BPA效果的影响。结果表明,当入口压力为0.3 MPa、溶液pH为3、Fe~(2+)的质量浓度为1.65 mg/L及H_2O_2的质量浓度为8.0 mg/L时,HC-Fenton对BPA去除率为61.61%,反应速率常数为9.49×10~(-3)min~(-1),且降解反应属于1级动力学反应。HC-Fenton能有效降解水中BPA,可为有机废水处理提供一种新方法。
The degradation effect of bisphenol A(BPA) by the hydrodynamic cavitation(HC) combined with Fenton(HC/Fenton) was studied. The effect of inlet pressure, solution p H, Fe~(2+)content and H_2O_2 content on BPA degradation effect was discussed. The results showed that, the BPA removal rate was 61.61% when inlet pressure, solution pH, mass concentration of Fe~(2+)and H_2O_2 was 0.3 MPa, 3, 1.65 mg/L and 8.0 mg/L respectively, the reaction rate constant was 9.49×10~(-3) min~(-1), and the degradation reaction belonged to the first order kinetics reaction. That HC/Fenton have positive effects on BPA degradation and provide a new method for organic wastewater treatment.
