中文摘要 |
考察了DLNF2-30(0.24m2)、MPS-44(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200mg/L 时,对废水浓缩10~20倍后洁霉素浓度可浓缩至2000mg/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%. |
英文摘要 |
Two spiral nanofiltration membranes, MPS-44 (1.4m2) and DLNF2-30 (0.24m2), 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 CODCr retention was always above 80%, and the lincomycin retention was always over 90%, and the lincomycin recycle rate was over 90%. |
