APPLICATION OF NOVEL PDMS PHASE INVERSION MEMBRANE IN EXTRACTIVE MEMBRANE BIOREACTOR

  • 摘要: 萃取膜生物反应器(EMBR)可将难降解的苯酚高盐废水分离为易降解的低浓度苯酚废水,从而实现苯酚高盐废水的高效降解。针对EMBR中传统硅橡胶管式膜苯酚跨膜传质速率较慢的问题,研究采用相转化法直接制备聚二甲基硅氧烷(PDMS)薄膜,可同时实现苯酚高渗透性与无机盐高截留率。探究了萃取膜生物反应器中废水、微生物单元的流量、pH、温度等参数对苯酚跨膜传质与无机盐截留的影响,优化了EMBR运行条件,并探究了EMBR内微生物的苯酚降解能力及对苯酚跨膜传质的影响。研究发现EMBR最优运行条件:废水单元流量为0.17 L/h、pH值=5.1、温度为34℃;微生物单元流量为0.17 L/h、pH值=5.75、温度为30℃。投加微生物后,该EMBR的苯酚跨膜传质系数最高可达到(4.0~4.3)×10-7 m/s,苯酚去除率始终维持在100%,NaCl截留率高于99.9%。研究成果有助于解决EMBR应用推广的瓶颈,对我国水环境污染治理和水资源安全保障有积极意义。
