摘要
Fenton试剂法处理有机废水是一种经典的催化氧化法,适合于处理废水中高浓度、难降解的有机物质。本文主要研究了光助Fenton试剂处理含苯酚水样的反应机理和影响因素,讨论了pH值、FeSO4、H2O2、催化剂纳米m-TiO2、紫外光照反应时间等因素对苯酚废水氧化降解效果的影响。结果表明:对水样中苯酚的去除率均可达到95%以上,用光助Fenton法处理苯酚有机废水是一种非常有效的方法。
The Fenton reagent treatment method for organic wastewater which is especially suited to treat those organic substances which are difficult to be biotreated and are proved to be destroyed inefectively by ordinary oxidative reaction organic substances, is a classic and strong oxidation reaction method. Some important factors such as pH, quantity of FeSO4, H2O2, TiO2 which are important to the degradation of phenol were investigated systematically. Experimental results show that the degradation rate can reach 95%.
