摘　　要：根据生物脱氮反应中废水的硝化和反硝化特点、原理及化纤含氰废水场生物脱氨装置的运行实践，改进了制约生物脱氮反应的硝化和反硝化反应条件；严格控制溶解氧含量；在相同进水量的情况下，使氨氮合格率由27．5％提高到89．5％。According to nitrification and denitrication characteristics and principles of waste water in biological denitrogenation reaction and operation practice in biological denitrogenation unit in chemical fiber cyanide-containing waste water treatment plant, the nitration and denitrification reaction condihons constrained the biological denitrogenation reaction are improved and the dissolved oxygen coment is strictly controlled. Under the same water intake conditions, ammonia nitrogen acceptable rate is increased from 27.5% to 89.5%.
