| 摘 要： | 研究次氯酸钠、双氧水、过氧乙酸等氧化剂对芳香聚酰胺反渗透膜性能的影响.通过膜表面接触角、膜通量、截留率以及表面化学结构等表征,重点考察了pH、氧化剂浓度以及处理时间对膜的分离性能和化学结构的影响.结果表明,芳香聚酰胺反渗透膜对过氧乙酸和双氧水具有较好的抗氧化性能,其对次氯酸钠的抗氧化性能与pH、次氯酸钠浓度、处理时间等有关.为芳香聚酰胺反渗透膜的有机生物污染处理工艺的选择提供理论和试验依据.

| Abstract: | In this paper,we studied the performance change of the aromatic polyamide reverse osmosis membrane treated with different oxidant agents such as sodium hypochlorite,hydrogen peroxide and peracetic acid.The membrane properties were characterized in terms of membrane surface contact angle,mem-brane flux,retention rates and surface chemical structure as well.Oxidation experiments were conducted under different pH,concentrations of oxidant agent and time of treatment.The results show that the aromatic polyamide... |
