摘要
从膜过滤阻力角度,分析了自生动态膜的形成过程和形成机理;对自生动态膜组件形式和自生动态膜反应器进行了简单的分类;从曝气方式和强度、出水水头、污泥性质和膜基材特性4个方面分析了影响自生动态膜稳定运行的因素。虽然自生动态膜技术相比其他的水处理技术有巨大的优势,但该技术还尚未完全成熟,相关的研究工作还需要持续进行。
According to the resistance of membrane filtration,the formation process and formation mechanisms ot self-generated dynamic membrane have been analyzed. The self-generated dynamic membrane module and self-gene- rated dynamic membrane bioreactor （DMBR） are classified briefly. The factors which have influence on the stable operation of self-generated dynamic membrane are analyzed from four aspects ： aeration intensity and aeration mode, water head-drops,sludge properties and film substrate properties. Compared with other water treatment technolo- gies, DMBR has some huge advantages, but it is not mature completely,yet. The research related to it should keep on going.
