| 摘 要： | 文章主要研究膜分离-光催化组合工艺中膜污染的控制措施。研究表明,该体系中,膜可逆阻力是造成膜污染的主要因素。通过减小抽吸压力,提高曝气强度,间歇抽吸等措施可以有效地减小膜可逆污染。实验表明:最佳抽吸压力为0.02MPa,经济曝气量为0.4 m3/h,采取抽吸13min、停抽2min的运行模式。膜不可逆污染可通过化学清洗加以去除。

| Abstract: | Measures of membrane pollution control in the process of membrane separation combined with photocatalysis was studied, and results indicated that membrane reversible resistance was main factor to arouse membrane pollution. Measures including reducing pumping pressure, improving aeration intensity and intermittent pumping can effectively reduce the membrane reversible pollution. Membrane pollution can be removed under optimum pumping pressure of 0.02MPa, aeration of 0.4m3/h, pumping of 13min and retention of 2min. |
