用螺旋藻吸收去除尿液中氮、磷和有机物 总被引：1，自引：0，他引：1
针对资源化回收利用尿液中主要营养物质的问题,在实现尿液培养螺旋藻的基础上,探讨螺旋藻对尿液中主要营养物质氮、磷和有机物的吸收和去除.螺旋藻对尿液中氮素的吸收与螺旋藻生物量的变化保持一致,最大吸收率可达59.92%;尿液中约64.15%的磷被去除,其中螺旋藻的理论吸收约占39.24%,其余24.91%可能以沉淀形式离开尿液;螺旋藻对尿液中有机物的吸收最高可达58.4%,尿液中的有机物有助于螺旋藻的生长.研究结果为尿液的资源化回用开辟1种途径. 相似文献

INTRODUCTION For long distance manned space missions, bio- logical life support systems (BLSS) have to be in- troduced into the life support system to achieve regeneration of nutrient matter (Volker and Frank, 2001). Recently, many kinds of subsystems within BLSS have been proposed and experimented on solely or jointly, which include mainly higher plant, aquatic organisms (Volker and Frank, 2001), micro- organisms and microalgae (Gros et al., 2003). Mi- croalgae were incorporated in … 相似文献
