【摘要】 考察了DLNF2 30 ( 0 2 4m2 )、MPS 4 4( 1 4m2 ) 2种卷式纳滤膜串联运行时对洁霉素废水中残余洁霉素的浓缩性能 .实验结果表明 ,当进水中洁霉素浓度为 2 0 0mg/L时 ,对废水浓缩 1 0～ 2 0倍后洁霉素浓度可浓缩至2 0 0 0mg/L以上 ,满足回用要求 ,浓缩时间为 60～ 70h .在浓缩过程中 ,CODCr的截留率始终高于 80 % ,洁霉素截留率始终高于 90 % ,且洁霉素的回收率高于 90 %更多还原

【Abstract】 Two spiral nanofiltration membranes, MPS 44 (1 4m 2) and DLNF 2 30 (0 24m 2), were connected in series to test the concentration process of lincomycin wastewater. Results indicated when the water inflow concentration was about 200mg/L, the lincomycin concentration can reach 2000mg/L after being concentrated for about 10～20 times. Such concentration can reach the demand of reuse, and the concentrating time was 60～70 h. During the concentration process, the COD\-\{Cr\} retention was always above 80%, and the lincomycin retention was always over 90%, and the lincomycin recycle rate was over 90%.更多还原
