摘要
采用Fenton法对医药废水进行预处理。当原水COD约为11000mg／L时，COD去除率可达90％以上，并得到最佳操作条件为：H2O2投加量为60g／L，Fe^2＋投加量为1．0g／L，反应时间为30min，pH=4．0—6．0。对比反应前后的紫外光谱说明，经Fenton反应后原水中的芳香化合物已得到了彻底的氧化分解。
Fenton process is used as a pretreatment method to treat pharmaceutical wastewater. The results show that the removal of COD could arrive at above 90% with the best operation condition of 1.0 g/L of C （ Fe^2＋ ） and 30rain Of time and 60mg/L of C （ H2O2 ） and 4. 0 to 6. 0 of pH. The ultraviolet spectrum indicates that after Fenton process the aromatic compounds are oxidized completely.
