微纳米气泡对超滤膜过滤腐植酸污染影响研究

文章导读

摘要为有效解决超滤过程中因有机物堵塞膜孔导致的膜污染和渗透通量下降问题，提出在对腐植酸（HA）溶液超滤传输及反洗过程中引入微纳米气泡水处理工艺，以强化超滤过程，实验研究了微纳米气泡对超滤膜渗透通量和截留效率的影响以及膜污染去除效果。结果表明在纯水和HA溶液中鼓入微纳米气泡后其归一化通量增大到1.1~1.3，截留效率提高了2.5%~22.0%，微纳米气泡水清洗和反洗后膜通量恢复分别高于纯水21%和25%。

Abstract： In order to effectively solve the problems of membrane fouling and reduction of permeate flux caused by natural organic matter during the ultrafiltration (UF) process, micro-nano bubbles (MNBs) water treatment was introduced during the UF transport and backwashing process of humic acid (HA) solution to strengthen the UF process. The effects of MNBs on the permeate flux, rejection coefficient and the membrane defouling were studied. The results showed that the normalized flux of pure H₂O and humic acid (HA) (5 mg·L^-1) solution increased to 1.1—1.3 and the rejection coefficient of HA increased by 2.5%-22.0%. The normalized flux recovery increased by 21% and 25% after cleaning and backwashing in the presence of MNBs, respectively.
