摘要
在错流流速5m.s-1、压力0.3MPa、温度20℃条件下,用0.2、0.5、0.8μm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.
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.
