摘　　要：采用中空纤维膜作生物膜载体及无泡供氧装置,利用具有死端式和漂浮式特点的浸没式接触氧化工艺进行污水处理试验研究.结果表明:在控制系统工作压力0.03 MPa、污水中ρ(DO)为5～8 mg/L及HRT＝8h的条件下,污水中COD、BOD、SS的去除率分别达70%、90%和75%以上,NH3 -N、P的去除率也在70%以上.系统连续运行3个月,表现了较好的稳定性和抗有机负荷冲击能力.Hollow fiber membrane was used as bio-film carrier and bubbleless device in the wastewater treatment experiment. The experiment also made use of submerged contact oxygenation technique,which had dead-end and floating merits. The results showed that the removal ratio of COD, BOD and SS was 70%, 90% and 75% respectively when working pressure was 0.03 MPa, DO was 5～8mg/L and HRT was 8 h in the system. Study also showed that the removal ratio of NH_3-N, P was more than 70%. The system has better stability and resistence to substrate flux after three months of continuous running.
