報告簡介:
This presentation will discuss the integration of electrochemical reactions and membrane separation to augment the deficiency for trace level micropollutant removal and potential resource recovery. Electrochemically reactive or electrified membrane technologies have the potential to address inherent limitations of conventional membrane technologies such as capture and enhanced degradation of those micropollutants with small molecular sizes and low concentrations. Moreover, electrified membrane technologies exhibit strong antifouling features against a suite of different inorganic and organic foulants. This presentation will cover three topics: (1) algal biomass and algogenic odor removal using the tubular Ti4O7 membrane (2) the electrically assisted adsorption of a broad range of short chained per- and polyfluoroalkyl substances (PFAS) using externally charged electrically conducting membranes (ECMs) made of selected carbonaceous nanomaterials (CNMs) or transition metal carbides (MXenes); (3) electrified membranes for synchronizing electrochemical NO3?reduction and upcycling to NH3 without any external chemical addition.
本報告將討論如何將電化學反應與膜分離技術相結合,以克服其在痕量微污染物去除和潛在資源回收方面的不足。電化學反應或電化學膜分離技術有可能解決傳統膜過濾系統的固有局限性,如捕獲小分子、增強對低濃度微污染物的降解。此外,電活性薄膜能夠將截留的無機\有機污染物原位電化學氧化降解或將微生物原位滅活,具有“自清潔”功能。本報告將涵蓋三個主題: (1) 利用管狀 Ti4O7 電化學膜過濾系統高效去除藻類物質;(2) MXene基電催化膜過濾系統對全氟烷基羧酸(PFCAs)的電吸附、電解吸和降解機制研究。(3) 無外加化學物質的情況下,利用新型電氣化膜工藝實現水中硝酸鹽 (NO3?)還原和氨 (NH3)轉化回收。
