The emergence of the aluminium recycling industry has led to an increase in aluminium-containing wastewater discharge to the environment. Biological treatment of metal is one of the solutions that can be provided as green technology. Screening tests showed that Brochothrix thermosphacta and Vibrio alginolyticus have the potential to remove aluminium from wastewater. Brochothrix thermosphacta removed up to 49.60%, while Vibrio alginolyticus was capable of removing up to 59.72% of 100 mg/L aluminium in acidic conditions. The removal of aluminium by V. alginolyticus was well fitted with pseudo-first-order kinetics (k = 0.01796/min), while B. thermosphacta showed pseudo-second-order kinetics (k = 0.125612 mg substrate/g adsorbent. hr) in the process of aluminium removal. V. alginolyticus had a higher rate constant under acidic conditions, while B. thermosphacta had a higher rate constant under neutral pH conditions.
铝回收产业的出现导致含铝废水排放量增加到环境中。金属的生物处理是可以作为绿色技术提供的解决方案之一。筛选试验表明，嗜热解糖梭菌和 Alginate 降解弧菌有从废水中去除铝的潜力。嗜热解糖梭菌最多可去除 49.60%，而 Alginate 降解弧菌在酸性条件下可去除高达 59.72%的 100mg/L 铝。Alginate 降解弧菌对铝的去除符合准一级动力学（k=0.01796/min），而嗜热解糖梭菌在铝去除过程中则表现为准二级动力学（k=0.125612mg 底物/g 吸附剂.hr）。Alginate 降解弧菌在酸性条件下具有更高的速率常数，而嗜热解糖梭菌在中性 pH 条件下具有更高的速率常数。
