摘要
采用三维电极-电Fenton耦合法降解模拟苯酚废水,验证模拟苯酚废水降解过程中羟基自由基的存在,考察不同电压、起始p H值、铁粉加入量、曝气等因素对羟基自由基生成量的影响,实验结果表明:当溶液的p H为6.86(原溶液),加入3.0 g/300 m L Fe粉,5 V电压下1.5 L·min-1的曝气下电解30 min后,苯酚降解过程中羟基自由基的生成量最大。
In this work, three-dimensional electrodes-electrical Fenton method was used to degrade phenol wastewater, the existence of ·OH free radical was validated in the process of phenol wastewater treatment. The effect of operating conditions including electrolytic voltage, initial p H, amount of Fe particles and aeration on the formation of the ·OH free radical was investigated. The results show that the best ·OH free radical formation condition is as follows： the initial p H 6.86, Fe particles dosage 3.0 g/500 m L, aeration amount 1.5 L·min-1, cell voltage 5 V and electrolysis time 30 min.
