摘　　要：纳滤膜处理工业废液时,纳滤膜系统可以看做一个封闭体系。实验表明透过液通量Jw与压力差呈直线关系;透过液通量Jw与透过液溶质浓度CR都与浓缩时间呈较好的数学关系,但数学关系形式不同;透过液溶质浓度CR与进液溶质浓度Ci呈指数关系;透过液溶质浓度CR与膜压力差Δp的关系为指数关系。When nanofiltration is used for industrial waste liquid treatment, the system can be seen as a closed-system. The mathematical relationship between permeate flux Jw and pressure difference is linear. Both permeate flux Jw and solute concentration CR of permeate have mathematical relationship with concentration time, but the styles are different.The relationship between solute concentration CR of permeate and solute concentration of concentrate is exponential, the relationship between solute concentration CR of permeate and pressure difference Δp is also exponential.
