英文摘要: With cellulose as the polymer materials, monohydrate N-methylmorpholine-N-oxide (NMMO center dot H2O) as the solvent, polyethylene glycol (PEG400) as the additives, asymmetric hollow fiber ultrafiltration membranes were prepared by the immersion phase inversion technique. Water was used as both the internal and external coagulant. The performances of the membrane were characterized by pure water flux. Experimental researches on treatment of oil-water emulsion by using cellulose hollow fiber membranes were performed. The results show that the treatment of oily wastewater by cellulose membrane is feasible and desirable. The oil eliminating efficiency of over 99% and oil concentration of less than 10 mg/L after the filtration were achieved, which can meet the requirement of drainage. The influences of different cleaning methods( physical cleaning, physical cleaning and 0.1 mol/L HCl solution, physical cleaning and 0.1 mol/L NaOH solution) on the cleaning of fouled cellulose membranes were investigated. The results show that the flux recovery of physical cleaning and 0.1 mol/L NaOH processes is 99%.
