    Before the running of the MBR, kaolin micro-particles with a mean diameter of 2μm were membraned on the inner wall of the ceramic membrane tube as the dynamic membraneto filtrate the simulated caprolactam wastewater. Results indicate that removal rate is higher and flux decline becomes much slower than filtrating directly with ceramic membranes. Through operating at low pressures, good performance provides warranty for MBR to reduce energy consumption.

Liquid-liquid equilibrium data of caprolactam-H 2O-(NH 4) 2SO 4-C 6H 6 system at low caprolactam concentrations were measured (overall 33 data points). The data are correlated with satisfactory accuracy by the proposed equation: w′ 1=w 1(a+bw 1),where w 1 and w 1′ are mass fractions of caprolactam in the water phase and the benzene phase,respectively. The parameters a and b for the above data are:(1) 20℃,pH=5.7:a=0.2287,b=0.7995;(2)30℃,pH=5.7:a=0.2029,b=2.8060;(3)30℃,pH=4.0:a=0.2128,b=1.7409;(4)30℃,pH=2.0:a=0.1982,b=1.4744...
