  • 摘要: 主要研究了DL1210型纳滤膜去除水中邻苯二甲酸二丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）、乐果和莠去津的影响因素，考察了温度、pH值、初始浓度、跨膜压力（TMP）和运行时间对膜通量和截留率的影响。结果表明，纳滤工艺是去除水中微量DBP、DEHP、乐果和莠去津的有效方法，初始pH值和温度的升高会导致纳滤膜对DBP、DEHP、乐果和莠去津的截留率的降低，膜对DBP和DEHP的截留率随初始浓度的升高而降低，TMP和运行时间不会对膜通量和目标污染物的截留率造成显著影响。当初始pH为5、初始浓度为5 μg/L、温度为5℃、TMP为0.4 MPa时，纳滤工艺对DBP、DEHP、乐果和莠去津的截留率达到最佳，分别为91.8%、89.8%、98.02%和77.6%，出水中DBP、DEHP、乐果和莠去津浓度分别为0.41、0.49、0.099和1.12 μg/L。
    Abstract: Several factors such as temperature, pH, initial concentration, transmembrane pressure (TMP) and running time which affect membrane flux and retention efficiencies were investigated by using DL1210 nanofiltration membrane to remove dibutyl phthalate (DBP), phthalate, bis (2-ethylhexyl) ester (DEHP), dimethoate and atrazine. The results showed that the nanofiltration process is an effective method to remove traces DBP, DEHP, dimethoate and atrazine. The retention efficiencies of nanofiltration membrane on DBP, DEHP, dimethoate and atrazine decreased with an increase in pH and temperature. And the membrane retention efficiencies on DBP and DEHP also decreased with an increase in initial concentration. However, TMP and running time have no significant impact on the membrane flux and the retention efficiencies of target pollutants. Finally, The nanofiltration process achieved the best retention efficiencies on DBP, DEHP, dimethoate and atrazine under the condition of the initial pH of 5, the initial concentration of 5 μg/L, a temperature of 5℃ and TMP of 0.4 MPa with retention efficiencies of 91.8%, 89.8%, 98.02% and 77.6%, respectively. And the effluent concentrations of DBP, DEHP, dimethoate and atrazine were 0.41, 0.49, 0.099 and 1.12 μg/L, respectively.
