| 摘 要： | 采用催化湿式氧化处理头孢氨苄废水,考察反应温度、进水pH及Cl-含量对RCT催化剂性能的影响,并对液体样品及催化剂进行了HPLC、TOC/TN、GC-MS、N2物理吸附-脱附及XRF表征。通过正交实验,得出最佳的工艺条件为:进水pH=4.8,Cl-浓度1 500 mg·L-1,反应温度260℃;对催化剂进行300 h连续寿命考察,废水TOC及TN去除率均超过90%,催化剂稳定性高,活性组分流失较少;废水经催化湿式氧化处理,水中残留的主要有机物均可生化降解。

| Abstract: | Catalytic wet air oxidation was employed to treat cephalexin wastewater,and the effects of reaction temperature,pH and Cl- content were investigated.Liquid samples and catalysts were characterized by HPLC,TOC/TN,GC-MS,N2-Physisorption and XRF.Orthogonal experimentalresults showed that the optimal reaction conditions were:reaction temperature was 260 ℃,Cl- content was 1500 mg·L-1 and pH was 4.8.RCT catalyst exhibited high TOC/TN removal(over 90%),high stability and low active met al loss during 300 h reaction test. And the main organic residues after CWAO werebiodegradable. |
