摘　　要：1 引言硝基酚往往由中小厂生产,小厂设备简陋,其废水往往不加处理,直接排放。由于硝基酚的毒害比苯酚更大,所以严重污染环境。用液膜技术处理废水,设备简单,效果优良,很适合中小厂应用,值得对此详细研究。This nitrophenol wastewater was treated with liquid membrane process. The linear relationship In (C_0/C_1) and t was obtained. The effects of parameters such as R_(oi),R^(ew),r on the nitrophenol mass transport velocity was determined. The experiment showed that the addition of the carrier TBP in membrane phase significantly increaed velocity of nitrophenol mass transport.The mechanism of mass transport of nitrophenol was discussed. It was found that the velocity-determining step was diffusion of nitrophenol in the membrane phase, which distinguished from the process of phenol mass transport.
