Sewage can become a valuable source if its treatment is re-oriented for recovery. An anaerobic forward osmosis membrane bioreactor (AnOMBR) was developed for real municipal sewage treatment to investigate performance, biogas production, flux change and mixed liquor characteristics. The AnOMBR had a good treatment capacity with removal ratio of chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus more than 96%, 88%, 89% and almost 100%. Although high DS concentration increased the initial flux, it caused rapid decline and poor recoverability of FO membrane flux. Low DS concentration led to too long hydraulic retention time, thus resulting in a low reactor efficiency. Additionally, it was observed that salt, protein, polysaccharide and humic acid were all accumulated in the reactor, which was not conducive to stable long-term operation. Based on the characteristics of membrane fouling, salt accumulation and AnOMBR performance, the optimal DS of 1 M NaCl solution was selected.

如果将污水处理方法重新定位以使其恢复，污水将成为有价值的来源。开发了用于实际市政污水处理的厌氧正渗透膜生物反应器（AnOMBR），以研究其性能，沼气产生，通量变化和混合液特性。AnOMBR具有良好的处理能力，化学需氧量，氨氮，总氮和总磷的去除率分别超过96％，88％，89％和几乎100％。尽管高DS浓度会增加初始通量，但会导致FO膜通量迅速下降和可恢复性差。低DS浓度导致水力停留时间过长，从而导致反应器效率低。此外，观察到盐，蛋白质，多糖和腐殖酸都积聚在反应器中，这不利于稳定的长期运行。根据膜污染，盐分积累和AnOMBR性能的特点，选择1 M NaCl溶液的最佳DS。
