结合工程实际采用水解酸化-SBR工艺处理制药废水，处理水量为2000m^3／d。SBR对CODcr，的处理率稳定在92．2％～95．8％间，平均为94．23％，对氨氮的去除率在82．7％-97．6％，平均去除率达到90．73％。水解酸化-SBR稳定运行后，系统出水各项指标均达到国家《污水综合排放标准》（8978-1996）二级排放标准。运行结果表明，SBR运行最佳参数为：曝气时间8小时，污泥负荷控制0．23～0．28（kgCODcr，／kgMLSS·d、．温唐26℃。30℃．该工尹用干盘卜理高．廒唐制菇鹰水效粟稳定．而十冲击盎菥高．%A total 2000 m^3/d of pharmaceutical wastewater was treated with hydraulic acidification -SBR（ Sequencing Batch Reactor） oxidation method. The treatment rate of COD is about 92. 2% ～ 95.8% with average of 94. 23%. The treatment rate of NH3 - N is between 82. 7% - 97.6% with average of 90. 73%. After stable operation of system, all indexes of the effluent can meet the Second Grade Standard of GB8978 - 1996. The results show the optimum operation parameters of SBR are as follows, aeration time 8 h, sludge limitation load 0. 23 ～0. 28 （kg CODor/kg MLSS · d）and temperature 26℃ ～ 30℃. The results proved that the effect of this technology is steady and can adapt to major fluctuations.
