Abstract
Based on wastewater recycling, a positively charged composite nanoflitration membrane prepared by ourselves is applied in the treatment of waste-water drained from the production of sodium alginate. These factors affecting nanofiltration process including operating pressure, cross-flow rate and the cleaning membrane are investigated. And the removal of total solubility solid, salinity and CODCr, etc through this membrane are determined. The results suggest that the after waste water is treated through nanofiltration, the concentration of CODCrin the effluent is 21.4 mg/L, and the removals of CODCrand rigidity reach 93.0% and 88.3%, respectively, which realizes the desalination of waste-water and the removal of organic substances, the effluent may be reused for process technology.
