利用人工小球藻-灵芝菌共生体在光生物反应器系统中,对预处理后的沼液进行了生物净化处理研究。考察了红色光质和蓝色光质的不同混合光质(红光:蓝光比为8:2;5:5和2:8),在不同受理时间下的沼液净化效果。结果表明,藻菌共生体对主要污染物的去除效果受处理时间影响显著(P < 0.05),实验启动1~4 d去除效果增加明显。同时,当红光:蓝光为5:5时,沼液中COD、TN和TP去除效果均为最佳,去除率分别达到80.42% ± 6.36%,75.63% ± 6.56%和78.83% ± 6.35%。 In this work, we selected the technologies involving the co-cultivation of Scenedesmus obliquus with Ganoderma lucidum cultured in photobioreactor to research the pretreated biogas slurry nutrient removal. The selected light qualities were mixed red light and blue light (red:blue = 8:2, 5:5, 2:8) under difference process time. The results show that the artificial algal-fungal symbiont has significantly higher nutrients removal efficiency (P < 0.05) by process time under its treatment, and in the initial time 1 - 4 d, the nutrients removal efficiency was increased dramatically. The red: blue = 5:5 achieved the highest COD (80.42% ± 6.36%), TN (75.63% ± 6.56%) and TP (78.83% ± 6.35%) removal efficiency by the artificial algal-fungal symbiont.
