摘　　要：采用移动床生物膜反应器(MBBR)对中国石油兰州石化公司含硫催化剂污水生化系统进行了改造。结果表明,进水量由改造前的4.90 m3/h提高到改造后的23.47 m3/h。改造后,进出水氨氮化合物平均质量浓度分别为97.55,3.27 mg/L,进出水化学需氧量平均质量浓度分别为380.7,59.9 mg/L,排水达到GB 8978—1996标准要求。此外,改造后装置运行成本较改造前降低了2.36元/t。The revamping of a biochemical treat- ment for sulfur- containing catalyst waste water was conducted by moving bed biofilm reactor（MBBR） in Lanzhou Petrochemical Company. The results showed that after the revamping, the processing capacity of system increased from 4.90 m^3/h to 23.47 m^3/h. The average mass concentration of ammonia and ni- trogen based compounds and COD of influent and ef-fluent waters were 97.55,380.7 mg/L and 3.27, 59.9 mg/L respectively,which met the standard of GB 8978--1996. In addition, the operation cost of the unit was decreased by 2.36 yuan/t.
