Real pharmaceutical wastewater was treated by photocatalytic oxidation and catalytic wet air oxidation (CWAO) processes. The catalytic performance of Fe/AC and LaFeO₃/AC (AC: Commercial activated carbon) was compared in the advanced oxidation processes. The influences of the reaction parameters were determined by using Box–Behnken design. Fe/AC catalyst was more effective in both of the photocatalytic oxidation and catalytic wet air oxidation processes. In the photocatalytic oxidation process, 72.7% COD removal was achieved at pH = 4.5, 2.0 g/L, and [H₂O₂]_o = 0.32 mM. Under the optimum conditions of the CWAO, which were determined as 3 g/L of catalyst loading, pH = 3, and 50℃, 83.1% COD removal efficiency was obtained. CWAO method was determined as more suitable since a higher COD removal efficiency was achieved in a shorter reaction time. The toxicity in terms of L. sativum growth inhibition was evaluated as 4.82% after the CWAO treatment. A two-step first-order reaction kinetics provided the best fit of the CWAO experimental data. The activation energies of the fast and the slow steps were 25,661.16 and 28,327.46 J/mole, respectively.

真正的制药废水通过光催化氧化和催化湿空气氧化（CWAO）工艺处理。Fe/AC 和 LaFeO ₃ /AC（AC：商业活性炭）在高级氧化过程中的催化性能进行了比较。通过使用 Box-Behnken 设计确定反应参数的影响。Fe/AC 催化剂在光催化氧化和催化湿空气氧化过程中都更有效。在光催化氧化过程中，在 pH = 4.5、2.0 g/L 和 [H ₂ O ₂ ] _{o 条件下}，COD 去除率达到 72.7%= 0.32 毫米。在CWAO最佳条件下，即催化剂负载量为3g/L，pH=3，50℃，COD去除率达到83.1%。CWAO 方法被确定为更合适，因为在更短的反应时间内实现了更高的 COD 去除效率。在 CWAO 处理后，根据L. sativum生长抑制的毒性评估为 4.82%。两步一级反应动力学提供了 CWAO 实验数据的最佳拟合。快步和慢步的活化能分别为 25,661.16 和 28,327.46 J/mole。
