In this study, an anaerobic flat-sheet ceramic membrane bioreactor (AnCMBR) was used to treat high-strength dyeing wastewater, and compared with an upflow anaerobic sludge blanket (UASB) reactor. The start-up phases of the AnCMBR and UASB reactor were accomplished within 60 d by using cultivated seed sludge. The results showed that the AnCMBR had better COD, TN, and TP removal rates than the UASB reactor. The CH production of the AnCMBR was higher than that of the UASB reactor. The AnCMBR was operated with low energy consumption due to good water permeability of the flat-sheet ceramic membrane. The AnCMBR and UASB reactor had similar CH-producing Archaea; Methanosaeta, Methanosarcina, and Methanomassiliicoccus were the most abundant. The AnCMBR had a higher proportion of Desulfovibrio sp. and Desulfomicrobium sp., which are reported to have the potential to degrade reactive dyes. A large number of sulfate-reducing enzymes were deduced to contribute to the sulfate-reducing pathway.
在这项研究中，采用厌氧平板陶瓷膜生物反应器（AnCMBR）处理高强度染色废水，并与上流式厌氧污泥床（UASB）反应器进行了比较。通过使用培养的种子污泥，AnCMBR 和 UASB 反应器在 60 天内完成了启动阶段。结果表明，AnCMBR 对 COD、TN 和 TP 的去除率优于 UASB 反应器。由于平板陶瓷膜具有良好的水渗透性，AnCMBR 的 CH 产量高于 UASB 反应器。AnCMBR 以低能耗运行，因为平板陶瓷膜具有良好的水渗透性。AnCMBR 和 UASB 反应器中具有相似的产甲烷古菌；产甲烷菌属、甲烷八叠球菌属和甲烷微球菌属是最丰富的。AnCMBR 具有更高比例的脱硫弧菌属和脱硫微菌属，据报道它们具有降解活性染料的潜力。大量的硫酸盐还原酶被推断有助于硫酸盐还原途径。
