摘　　要：采用生物膜法Ａ／Ｏ（缺氧／好氧）系统处理化纤废水的试验结果表明，该系统处理化纤废水不但对ＣＯＤ、氰化物有较强的降解能力，而且对氨氮和总氮也有较好的去除效果。在缺氧段与好氧段的容积比为１：３，硝化液回流比为３：１，系统水力停留时间为４７ｈ时，生物膜法Ａ／Ｏ系统对化纤废水氨氮的去除率超过９０％，总氮和ＣＯＤ的去除率分别达到８０％和９０％以上。The experiment result of treating chemical fiber waste water with biological film technique A/O system shows that treating chemical fiber waste water with this system not only has stronger degradability to COD and cyanides, but also has better result of ammonia/nitrogen and total nitrogen removal.The volumetric ratio of anaerobic section /aerobic section is 1:3, the reflux ration of nitrate solution is 3:1, the system hydraulic residence time is 47 hrs. Ammonia/nitrogen removal rate form chemical fiber waste water with biological film technique A/O system is above 90%,removal rate of total nitrogen and COD reaches to 80% and above 90% separately.
