Nutrient removal from the effluent of an anaerobic moving bed biofilm reactor (AnMBBR) treated with microalgae was evaluated. Algal treatment was highly efficient in removal of nutrients and discharge limits were met after 3days. Extending the cultivation time from 3 to 5days resulted in a large increase in biomass, from 233.3±49.3 to 530.0±72.1mgL(-1), despite nutrients in the water being exhausted after 3days (ammonium 0.04mgL(-1), orthophosphate <0.05mgL(-1)). Biomass productivity, lipid content and quality did not differ in microalgal biomass produced in wastewater sampled before the AnMBBR. The longer cultivation time resulted in a slight increase in total lipid concentration and a significant decrease in linolenic acid concentration in all treatments. Differences were observed in chemical oxygen demand, which decreased after algal treatment in wastewater sampled before the AnMBBR whereas it increased after algal treatment in the effluent from the AnMBBR.
从经微藻处理的厌氧移动床生物膜反应器（AnMBBR）的废水中去除营养物的效果进行了评估。藻类处理对营养物的去除非常有效，3 天后就达到了排放标准。将培养时间从 3 天延长至 5 天，尽管 3 天后水中的营养物已耗尽（氨 0.04mg/L，正磷酸盐 <0.05mg/L），但生物量仍大幅增加，从 233.3±49.3 增加到 530.0±72.1mg/L。在 AnMBBR 之前采集的废水中的微藻生物量中，生物量生产力、脂质含量和质量没有差异。在所有处理中，总脂质浓度略有增加，亚麻酸浓度显著降低。化学需氧量（COD）也存在差异，在 AnMBBR 之前采集的废水中，藻类处理后 COD 降低，而在 AnMBBR 流出物中，藻类处理后 COD 增加。
