摘　　要：采用表面涂覆改性的方法制得新型的改性聚芳醚砜酮(PPESK)中空纤维疏水膜,并用真空膜蒸馏法(VMD)进行了水溶液中2,4,6-三氯酚的去除试验。分别考察了氯酚水溶液以及两种含氯酚废水中氯酚的去除效果,研究了料液进口温度(0～30℃)、真空侧压力(0.03～0.08MPa)对脱除率及脱除因子的影响。A new hydrophobic poly（phthalazinone ether sulfone ketone） （PPESK） hollow fiber membranes were prepared by surface-coated modification method. And the membrane was used to remove the 2,4,6-trichlorophenol from three different chlorophenol solution by vacuum memhran6 distillation （VIVID） method. The influence of temperature, the pressure on permeate side on the removal rate and the removal factors were studied respectively.
