摘　　要：通过向浸没式膜生物反应器 (简称 SMBR)中投加氢氧化铁絮体 ,经过驯化后 ,进而形成生物铁污泥 ,来实现膜污染的防治。在对模拟印染废水的处理过程中 ,从操作压力变化、膜污染电镜照片、污泥显微镜照片、污泥粒径分布等测定和观察结果来看 ,投加氢氧化铁絮体后增加了膜水通量 ,减小了膜污染。在机理上对此进行了详细的分析。Dosing ferric hydroxide into submerged membrane bioreactor and domesticating was expected to convert activated sludge into bio-ferric activated sludge so that membrane fouling was controlled. During dyeing wastewater treatment, it was seen from investigation of varieties of operation pressure, SEM of membrane surface, photograph of sludge and size distribution of sludge that addition of ferric hydroxide was an effective way to increase membrane flux and decrease the membrane fouling. The mechanisms were discussed in detail.
