摘　　要：以旋叶膜滤机作为过滤设备对光合细菌发酵液为过滤物料进行了动态微孔膜过滤特性的研究。将膜技术与动态过滤技术相结合是膜分离技术的一个热点,集二者各自的优点,对其进行研究和开发,既有理论意义,又有实用价值。在实验中研究了操作条件如转速、压力、浓度对微孔膜过滤速率的影响。过滤速率的衰减基本可分为2个阶段,即速率下降阶段和稳态过滤阶段。The dynamic performance of micro-filtration in the filtration of photosynthetic bacteria broth by rotating membrane filter was studied. The integration of membrane technology and dynamic filtration technology is a popular topic, which is of great importance in theory and practice. The influence of different operating conditions, such as rotating velocity, pressure, concentration of suspension, on rate of micro-filtration was investigated. It was discovered that the decay of filtration rate can be divided into two stages: drop stage and steady stage.
