As the world focuses on reducing greenhouse gas emissions and recovering energy from sewage, technologies that can recover energy and reuse wastewater are becoming increasingly important. Anaerobic membrane bioreactor (AnMBR) technology has recently attracted attention, as it can achieve energy recovery and yields high-quality effluent. However, the large-scale commercial application of AnMBRs requires that certain barriers be overcome, including membrane pollution and dissolved methane recovery. In this review article, we summarize the basic principles of anaerobic wastewater digestion and discuss the excellent performance of AnMBRs for wastewater treatment. Various factors, membrane types, and pollution are discussed, and control strategies for dealing with membrane pollution are put forward. In addition, a variety of new AnMBRs are described that may better control membrane pollution. Finally, future research directions for AnMBRs are presented to promote the large-scale integrated application of AnMBRs for industrial wastewater treatment.

In order to get optimal extraction performance as well as ultra-low solvent residual, three fluorinated hexane, perfluorohexane (C6F14), 1H-perfluorohexane (C6F13H) and 1H,6H-perfluorohexane (C6F12H2), were evaluated as diluents for synergistic effect on extraction capability of 1H,1H,2H,2H-Perfluorooctan-1-ol by the way of experimental and computational investigation. Based on extraction experiments, C6F14 showed obvious antagonistic effect because of hydrophobic nature, while the synergistic effect of C6F12H2 was better than that of C6F13H. According to DFT calculation, supported by FT-IR and 1H NMR spectra, the synergistic effect was illustrated as that fluorinated hexane could interact with salicylic acid-fluorinated octanol complex through hydrogen bond.
