摘　　要：以上海焦化有限公司废水为处理对象,研究了A1-A2-O生物膜系统的优化效果。研究表明:在优化条件下,COD的平均去除率为85.1%,氨氮的平均去除率为93.4%,TKN的平均去除率为83.9%;有机物和氨氮的去除主要发生在好氧段,含氮有机物在缺氧和好氧条件下都可以得到降解。Taked the Shanghai coked limited company waste water as the processing object to study the optimized effect on A1 - A2 - O biomembrane system. The research indicated that the COD average elimination rate was 85.1%, the ammonia nitrogen average elimination rate was 93.4%, TKN average elimination rate was 83.9% under the optimized condition. The elimination for organic matter and the ammonia nitrogen mainly occured in the good oxygen section. The organic matter contained nitrogen could be degenerated in the fire of the oxygen and good oxygen condition.
