Abstract: Micro-membranes with pore size of 0.2 μm，0.5 μm and 0.8 μm were used to treat the black liquor of paper-making under the following experimental conditions:cross flow velocity 5 m•s^-1,operation pressure 0.3 MPa and operation temperature 20℃.The separation of pollutants with inorganic membrane and the membrane cleaning method were investigated.Membrane separation used for black liquor recycling in the paper-making process was studied.

摘要： 在错流流速5 m•s^-1、压力0.3 MPa 、温度20℃条件下，用0.2、0.5、0.8 μm无机陶瓷膜对草浆造纸黑液进行了膜滤研究.考察了无机陶瓷膜对污染物的截留效果，探索膜的清洗与膜分离技术用于草浆造纸废液循环回用的途径.
