摘要
采用0.8μm无机陶瓷微滤膜对碱法草浆黑液进行微滤,确定了实验的最佳条件,并对微滤的截留液及透过液的木质素、COD、固形物等进行对比分析.结果表明:透过液COD的截留率达60%以上,木质素的截留率达85%以上.微滤3.5h后木质素浓缩比为2.47.
The making-paper black liquid was treated by0.8μm inorganic micro-porous membrane.The exˉperimental conditions were optimized.The experimental results show that theretention of COD was over60perˉcent.The lignin was over85percent.Concentration rate of lignin is2.47after3.5h.
