  • 摘要: 本研究采用膜蒸馏（MD）技术，对煤化工废水2套处理工艺——（1）“混凝-超滤（UF）-反渗透（RO）工艺”和（2）“混凝-活性焦（AC）吸附-超滤-反渗透工艺”的RO浓水进行浓缩。通过对比分析MD的膜通量、产水水质以及膜污染等指标，重点考察AC吸附预处理对后续MD工艺的影响。结果表明，AC吸附作为前置膜处理工艺，可有效降低污染物在膜表面的沉积，减少膜润湿现象，并提高膜通量。GC-MS分析表明，AC能有效吸附废水中的酮类、醇类、酯类以及杂环类等挥发性有机物，降低MD过程中挥发至产水侧的有机物浓度，从而提高MD产水水质。
    Abstract: In this work,membrane distillation (MD) was conducted to concentrate reverse osmosis (RO) retentate of two processes,(1) coagulation-ultrafiltration (UF)-reverse osmosis and (2) coagulation-activated coke (AC) adsorption-ultrafiltration-reverse osmosis.The purpose was to investigate the impact of AC adsorption on MD process by evaluating index such as membrane flux,permeate quality and membrane fouling.The results showed that AC adsorption pretreatment could effectively decrease the depostion of contaminants on the membrane surface,alleviate membrane wetting and improve the water flux.GC-MS analysis indicated that AC adorption could remove some volatile organic compounds such as ketones,alcohols,esters and heterocyclic compounds which could diffuse to the distillation,and thus improve the permeate quality of MD.
