摘　　要：采用次氯酸钠法、Fenton氧化法、微电解法及臭氧氧化法4种方法分别处理发酵类制药废水生化尾水,通过分析比较处理效果及运行成本,得出制药废水生化尾水的最佳处理方法,为解决该类废水的稳定达标排放问题提供新思路。实验结果表明,臭氧氧化法最适合处理该类制药废水。在最佳运行条件下,COD去除率可达56.78%,色度和TOC去除率分别为90.03%、36.23%,运行成本约2.9元/t。Four oxidation processes, including NaC10 oxidation process, Fenton oxidation process, micro- electrolytic and ozone oxidation are used to treat the biochemical fermentation effluent of pharmaceutical wastewater. The treatment effect is evaluated by the changes of COD, TOC and chromaticity. Through the comparative analysis af experimental treatment effect and operating costs, the most suitable method to treat the biochemical effluent of pharmaceutical wastewater treatment is con- eluded, which provides a new way of thinking to maintain the effluent receive qualified effluent water. The results show that, ozone oxidation method is best. Under the optimum condition, the removal rate of COD can reach 56.78%, the removal rate of chromaticity and TOC is 90.03% and 36.23% respectively and the operating cost is 2.9 Yuan per ton.
