title: [The application of nanofiltration membrane in the concentration and separation of lincomycin wastewater].
abstract: Two spiral nanofiltration membranes, MPS-44 (1.4 m2) and DLNF2-30 (0.24 m2), were connected in series to test the concentration process of lincomycin wastewater. Results indicated when the water inflow concentration was about 200 mg/L, the lincomycin concentration can reach 2000 mg/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%.
