中文摘要：
采用电／Fenton法降解阿莫西林模拟废水。结果表明，电／Fenton法集电解和Fenton于一体，电解作用能使溶液中的Fe^2＋在阴极还原再生Fe^2＋提供更多Fe^2＋催化H2O2，因而电／Fen—ton法对COD的去除效果优于Fenton法。当阿莫西林废水的初始浓度为0．1g／L时，分析各因素对COD去除效果的影响，得到最佳工艺参数：[H2O2]=13mmol／L、Fe^2＋和H2O2的物质的量之比为1：36、电流I=0．3A、pH值=4．5，在最佳条件下反应100min时，对COD的去除率达到70％，BOD5／COD值由零增至0．41。Fe^2＋和H2O2的最佳物质的量之比（1：36）同样适用于处理高浓度的阿莫西林废水。由于阿莫西林在反应初期降解速度很快，可使电解时间控制在反应的前10min。
英文摘要：
The electro-Fenton process was used to degrade synthetic amoxicillin wastewater. The experimental results show that the electro-Fenton process is superior to ordinary Fenton process in COD removal. This is mainly due to the electrochemical regeneration of Fe^2 ＋ at cathode, which can catalyze H20z. The effects of different factors on COD removal efficiency are analyzed when the initial concentration of amoxicillin wastewater is 0.1 g/L. Under the optimum reaction conditions of H2O2 = 13 mmol/L, Fe^2＋： H2O2 = 1 ： 36, I=0.3 A and pH =4.5, the COD removal rate of 70% and the BODJCOD ratio of 0.41 are achieved after 100 rain treatment. The Fe^2＋ ： H202 ratio of 1 ： 36 can also be used to degrade amoxicillin wastewater with high concentration. The electrolysis can be controlled at the first 10 min of the reaction time because the degradation of amoxicillin is very fast in this period.
