摘要/Abstract

摘要： 以海藻酸钠（ALG）为典型有机污染物，采用TFC FO膜，以水通量下降率和污染阻力作为膜污染的评价指标，探究了正渗透（FO）过程中的膜摆向（FO模式和PRO模式）、原料液（FS）和驱动液（DS）的浓度、原料液中Ca²⁺浓度和pH对FO膜污染的影响规律，并提出适宜的膜清洗方案。结果表明，在PRO模式下，膜污染阻力为3.38×10¹¹m^-1，而在FO模式下仅为3.88×10¹⁰m^-1，表明FO模式污染轻；FS或者DS浓度的增大均会导致污染阻力增大，使得污染更加严重；当FS中不含Ca²⁺和含Ca²⁺浓度分别为1mmol/L和2mmol/L时，相较于初始通量，其通量降低率分别15.40%、18.49%和24.93%，当Ca²⁺浓度从1mmol/L增大到2mmol/L过程中，膜污染阻力增大1.6倍；当FS的pH为4.2、7.0和10.7时，水通量降低率依次增加，分别为14.56%、14.82%和18.78%。分别采用去离子水、pH为3.0的HCl溶液、pH为11.8的NaOH溶液以及十二烷基硫酸钠（SDS，pH=11.0）溶液对膜进行清洗，得到SDS溶液清洗效果较好，通量恢复率可达90.70%。

Abstract: In this paper, sodium alginate (ALG)was used as the typical organic pollutant, and the water flux decrease rate and fouling resistance were used as the evaluation index of membrane fouling. The influence of the membrane orientation (FO mode and PRO mode), the feed solution (FS) and the driving solution (DS) concentration, Ca²⁺concentration and pH in FS on the TFC FO membrane fouling were studied. And a suitable membrane cleaning protocol was proposed. The results showed that the membrane fouling resistance was 3.38×10¹¹m^-1 in the PRO mode, and only 3.88×10¹⁰m^-1 in the FO mode, which indicated that the degree of fouling in PRO mode was more serious. When the concentration of FS or DS increased, led to the increase of fouling resistance, it made the fouling more serious. When there was no Ca²⁺ and the concentration of Ca²⁺ was 1mmol/L and 2mmol/L in FS, the flux reduction rate was 15.40%, 18.49% and 24.93% respectively. When the Ca²⁺ concentration increased from 1mmol/L to 2mmol/L compared with the initial flux, the membrane resistance increased by 1.6 times. When the pH of FS was 4.2, 7.0 and 10.7, the water flux reduction rate increased by 14.56%, 14.82% and 18.78%, respectively. In order to recover the membrane performance, the membrane was cleaned with deionized water, HCl solution with pH 3.0, NaOH solution at pH 11.8 and SDS (pH=11.0)solution, respectively. The results showed that SDS solution was the more effective cleaning protocol and the flux recovery rate was 90.70%.
