摘　　要：采用类芬顿氧化法,在紫外光辐照作用下,处理污水处理厂二级生化出水双酚A(BPA)。结果表明,初始在BPA的质量浓度为500μg/L的条件下,当Fe^(2+)的浓度为5μmol/L、H_(2)O_(2)的浓度为200μmol/L、溶液pH为8、反应温度30℃时,BPA的降解率最高。处理BPA的过程中会形成苯酚、对二苯酚等中间产物,并在羟基自由基(HO·)的作用下进一步分解。实验成果可应用于生产污水处理厂中二级生化出水残留BPA的处理。The fenton-like oxidation method was used to treat BPA in the secondary biochemical effluent of a sewage treatment plant under ultraviolet light irradiation.The results showed that when the initial mass concentration of BPA was 500μg/L,the concentration of Fe^(2+)was 5μmol/L,the concentration of H_(2)O_(2) was 200μmol/L,the solution pH was 8 and the reaction temperature was 30℃,the degradation rate of BPA was the highest.During the treatment of BPA,intermediate products such as phenol and p-diphenol were formed and further decomposed under the action of hydroxyl radical(HO·).The experimental results can be applied to the treatment of residual BPA in secondary biochemical effluent of production wastewater treatment plants.
