Abstract：

In order to study the treatment of the caprolactam waste water using membrane, the effect of concentration times on membrane flux, the quality of permeate and concentrate, including conductivity, COD and pH, was researched under certain conditions. In the experiment, reverse osmosis membrane was used to treat the wastewater which was provided by Ba Ling petrifaction. The results show that the reverse membrane can treat part of the caprolactam wastewater effectively and the quality of the producing water is stable. It also shows that the quality of permeate of backwashing water generated from ion-exchange process can fully meet the domestic industrial discharge standard, and that of polymerization wastewater could also reach the requirement of biochemical treatment under the optimal concentration times. For the feed wastewater in this experiment, the optimal concentration times for backwashing water generated in ion-exchange process is 8 and that for polymerization wastewater is 4～5.
