制药废水的处理方法很多 ，物化法主要有混凝沉淀法、 气浮法、 吸附法、 电解法和膜分离法; 化学法主要有催化铁内 电解法、 臭氧氧化法和 Fenton 试剂法; 生化法主要有序批式活性污泥法(SBR)、 普通活性污泥法、 生物接触氧化法、 上流式厌氧污泥床法(UASB) 等 〔2〕。 但上述单一处理方法的效果不好，出水水质不稳定 ，通常采用多种工艺联合处理，才能保证稳定的处理效果。 目前，多种处理工艺的联合使用在很多工程中得到应用 ，并取得了很好的效果 ，例如 UASB—CASS 工 艺 〔3〕、 水 解 酸 化—SBR 工 艺 〔4〕、 兼氧—深 曝—两 级 A/O 工 艺 〔5〕、 水 解 酸 化—接 触 氧化—气浮—氧化工艺

There are many methods of treatment of pharmaceutical waste water, which mainly include coagulant precipitation, air float, adsorption, electrolysis and membrane separation. The chemical method mainly has the catalytic iron solution, the ozone oxidation method and the Fenton reagent method; Biochemical method mainly order batch activated sludge process (SBR), the common activated sludge process, biological contact oxidation method, the upflow anaerobic sludge bed (UASB), etc. (2). However, the result of the single treatment method is not good, the water quality is unstable, and it is usually combined with various processes to ensure the stable treatment effect. At present, the combined use of A variety of processing technology has been applied in many projects, and achieved good results, such as UASB - CASS working art [3], hydrolysis acid - SBR art [4], and oxygen - deep revelation - the two levels of A/O worker skill [5], hydrolysis acid - contact oxidation - air flotation - oxidation process
