摘要:
随着水体污染的日趋严重,传统的净水工艺无法有效处理微污染水源。膜作为水处理中过滤屏障,可以截留大部分污染物以及99.9%的微生物,但由于水中溶质与膜材料之间相互作用会造成膜污染。通过Al-Ferron法研究聚合金属盐混凝剂的形态分布规律及其对膜污染的控制效果,结果发现铝盐水解形态中Alb形态占主导地位,AlT的总量减少,且经膜过滤后仅含少量的Alc,说明膜的截留效果比较好,另外膜的酸洗会比碱洗效果好,可以有效的减缓膜污染。

Abstract: With the increasingly serious water pollution, the traditional water purification process cannot effectively deal with slightly polluted water. Membrane, as a filter in water treatment, can intercept most pollutants and 99.9% of the microorganisms. However, membrane pollution occurs frequently due to the interactions between the solute and membrane with water flowing. In this paper, Al-Ferron process was utilized to investigate the morphological distribution of metal salt coagulants and improvement performance. Experimental results showed that in all forms of aluminum salt, Alb accounted for the most part, while the amount of AlT unfortunately reduced. Only a small part of Alc left after the filtration, which verified the good interception performance of membrane. In addition, membrane pickling will be more appropriate for slowing the membrane fouling than alkaline cleaning.
