摘　　要：含磺胺嘧啶(SD)和酮基布洛芬(KP)的化学合成制药生产废水对生物处理有较强的抑制作用。实验结果表明,通过对厌氧菌和好氧菌的驯化、筛选和复配,采用酸析作预处理,结合厌氧/好氧串联工艺可有效降低废水的COD、BOD5和NH3-N;经酸析和厌氧水解酸化处理后,COD去除率为85%,再经15h的好氧处理,COD去除率可达94%,运行效果稳定。A treatability study was performed on the wastewater （pH=11.5, COD=2 525 mg/L, BODs =915 mg/L, NH3-N=258 mg/L） from a pharmaceutical plant producing sulfadiazine （SD） and ketoprofen （KP）. Excellent treatment results were obtained by 3 sequential batch treatment steps of acidification/neutralization, anaerobic biodegradation and aerobic biodegradation. Duplicated experimental runs were conducted to obtain data of COD decline during acidification/neutralization, COD decline and gas production during anaerobic degradation at 34 ＂C, and COD decline during the final aerobic treatment step to define the most cost effective treatment procedure. The wastewater pH was first lowered to pH to 2.0 to promote hydrolysis then neutralized after 40 rain in the acidification/ neutralization reactor; the pretreated wastewater was then treated in the anaerobic reactor for 72 h and finally in the aerobic bioreactor for 15 h. Such sequential treatment achieved an overall COD reduction of 94%.
