摘要：在膜生物反应器基础上发展形成的序批式斜板动态膜生物反应器(SequencingInclinedDynamic

MembraneBiologicalReactor,SIDMBR)有其独特的性能。试验研究了140目不锈钢丝网为基材在曝气池内形成生物动态膜的启动过程和除污性能，并考察了稳定运行阶段，停留时间为24h,厌氧4h,好氧20h,溶解氧量为3mg/L时，SIDMBR对石油废水中COD、氨氮和石油的去除效果。结果表明：驯化期间反应器中COD、氨氮的去除率先急速下降再缓慢回升，石油的去除率先缓慢上升后快速上升，直至达到稳定状态。稳定运行阶段COD、氨氮和石油的平均去除率分别为93.9%、93.5%和99.0%。
