摘　　要：Dynamic membrane technology represents a promising substitution for conventional membrane bioreactor system,which owns the merits of flexible and comparably cheap materials,easy for backwash,good antifouling property,etc.It has been over half a century since the principle of dynamic membranes was first reported,whereas the development and popularization are still limited.This paper makes a review on characteristics of dynamic membranes,including development and application,mechanism,structure and materials,operation conditions,membrane fouling,dynamic membrane cleaning,and cost analysis,attempting to give clues on promotions and perspectives exhibited of this technology.Dynamic membrane technology represents a promising substitution for conventional membrane bioreactor system, which owns the merits of flexible and comparably cheap materials, easy for backwash, good antifouling property, etc. It has been over half a century since the principle of dynamic membranes was first reported, whereas the development and popularization are still limited. This paper makes a review on characteristics of dynamic membranes, including development and application, mechanism, structure and materials, operation conditions, membrane fouling, dynamic membrane cleaning, and cost analysis, attempting to give clues on promotions and perspectives exhibited of this technology.
