| 摘 要： | 以零价铁作为类芬顿反应中的催化剂，对某制药集团经生化处理后的制药废水进行深度处理。研究了H2O2和零价铁粉投加量、pH值以及Fe0的酸改性对处理效果的影响。结果表明：COD去除率20%时，可有效提高废水B/C比。在pH为3.0~3.5时，按H2O2：COD质量比为1：6进行投加，Fe0与H2O2按4：1的摩尔比投加，反应在2 h时能达到处理目标，即去除20%的COD。Fe0的重复使用性良好，5次后仍能保持催化效能，进一步对其中的反应过程与机理做了探讨。研究结果可为制药废水的深度处理提供参考。

| Abstract: | Zero-valent iron was used as the catalyst in the Fenton's reaction for the advanced treatment of pharmaceutical wastewater. The effects of H2O2 dosage, Fe0 dosage, pH value, and acid modification of Fe0 were studied. Results showed that COD removal of 20% was sufficient for B/C ratio improvement. The best operation conditions were as following:pH of 3.0 to 3.5, H2O2/initial COD of 1:6, Fe0/H2O2 of 4:1 (molar ratio), and reaction time of 2 h. Fe0 showed good reuse performance and the catalytic performance could be maintained after 5 times. The reaction process and mechanism were further discussed. The results can provide a reference for the advanced treatment of pharmaceutical wastewater. |
