Abstract This study compares the performance of two different systems (i) immobilized microalgae and suspended activated sludge (System A) and (ii) suspended co-culture (System B) in simultaneous treatment and biofuel production from domestic wastewater at different HRTs. The System A showed higher lipid content and carbon, nitrogen and phosphorous removal (40, 88, 91, and 93%) than System B (16, 87, 58, and 80%). C18:0 and C18:1n9t are dominant fatty acids observed in System A and C16:0 and C18:1n9t in System B. The immobilization of microalgae exhibited more benefits than suspended co-culture in terms of treatment and biofuel production.

利用微藻和活性污泥的固定和悬浮培养同时处理生活废水和生物脂质合成

摘要 本研究比较了两种不同系统 (i) 固定化微藻和悬浮活性污泥 (系统 A) 和 (ii) 悬浮共培养 (系统 B) 在不同 HRT 下同时处理和生产生活废水的生物燃料的性能。系统 A 显示出比系统 B(16、87、58 和 80%)更高的脂质含量和碳、氮和磷去除率(40、88、91 和 93%)。C18:0 和 C18:1n9t 是在系统 A 中观察到的主要脂肪酸,在系统 B 中观察到 C16:0 和 C18:1n9t。在处理和生物燃料生产方面,微藻的固定化比悬浮共培养表现出更多的好处。
