  • 摘要: 以提高目标物的降解效果和投加药剂利用率、缩短反应时间及节约处理成本为目的，探讨4种不同光助-Fenton氧化工艺对环境内分泌干扰物双酚A（BPA）的降解效果。以BPA的去除率和反应速率作为评价指标，采用紫外分光光度计、TOC测定仪及分子荧光光度计分别对BPA的去除率、反应体系的矿化度和·OH的生成量进行研究。确定了微波-Fenton氧化工艺降解水中BPA的效果最佳，并深入研究pH值、H2O2投加量、n（H2O2）/n（Fe2+）、微波反应功率及时间对微波-Fenton氧化工艺的影响。结果表明：pH=3，n（H2O2）/n（Fe2+）为20，H2O2浓度为2 mmol·L-1，反应时间为5 min，反应功率为300 W的条件下，BPA初始浓度为100 mg·L-1时其去除率最高达99.67%，矿化度达53%；pH值在2~6范围内对BPA均有降解效果，铁泥量也有一定的减少。为微波-Fenton氧化工艺的实际应用奠定了理论基础，并且提供了技术支持。
    Abstract: To improve the removal rate of the target compound and the reagent utilization efficiency, to shorten the reaction time, and to economize the treatment cost, four kinds of photo-Fenton oxidation processes on the degradation of BPA were discussed. Based on the evaluation index of the removal rate and the reaction rate constant of BPA, the removal rate of BPA, mineralization of the reaction system, and ·OH production were studied using ultraviolet spectrophotometer, TOC tester, and molecular fluorescence photometer, respectively. Mircowave-Fenton was verified as the best method for the degradation of BPA. The effects of pH value, H2O2 dosage, n(H2O2)/n(Fe2+), microwave power, and irradiation time on BPA degradation were investigated in detail. The results show that the optimal values of the operating parameters were found at pH of 3, n(H2O2)/n(Fe2+) of 20, H2O2 concentration of 2 mmol·L-1, microwave time of 5 min, and microwave power of 300 W. Under the optimal conditions, the removal rate of BPA reached 99.67% and the TOC removal was 53% when the initial BPA concentration was 100 mg·L-1. In particular, the degradation of BPA was good in the pH range from 2 to 6 and small amounts of iron sludge were produced during the reaction. This study should provide the fundamental basis and technical support for practical applications of microwave-Fenton-based advanced oxidative technology.
