摘要： 采用纳滤设备对干法腈纶废水进行深度处理, 考察了纳滤膜对COD、NH3 -N 及盐的截留率和脱色率的影响, 操作压力和运行时间对渗透通量的影响。结果表明, 经过纳滤技术处理后的水质COD 截留率大于96%, NH3 -N 截留率大于95%, 盐截留率大于94 .5 %, 脱色率高达100%。纳滤膜的渗透通量随着操作压力的增大而增大, 随着时间延长而下降。当操作压力为0.6 MPa 时, 纳滤膜的处理效果最好。该系统产水水质达到国家一级排放标准, 并可以回用做工业用水。

Abstract: The nanofiltration (NF) membrane was used in the advanced treatment of acrylic fiber wastewater. The COD and NH3-N removal efficiency, salt rejection and color removal ratio of the further treatment by NF were investigated. The influences of different operating pressures and operating time on permeate flux were also examined experimentally. The results indicate that the rejection ratio of COD and NH3-N are higher than 96% and 95% respectively. The salt rejection ratio is higher than 94.5% and color removal efficiency is up to 100%.The experimental results prove that the permeate flux of NF increases with operating pressure and decreases with operating time. The efficiency of NF is best when the operating pressure was 0.6 MPa. The effluent quality complies to national discharge standard and meets recovery criteria.
