摘要
目的进行受控生态生命保障系统(controlled ecological life support system,CELSS)氧气流动及废弃物发酵处理研究,解决载人航天工程技术发展中生命保障问题。方法以"人-红萍-鱼"CELSS的氧气流动为着眼点,详细分析了CELSS氧气生产与供应能力,得出氧气盈缺平衡能力。结果在剥离生物可降解废物氧化降解需氧量的情况下,栽培面积50.4 m^2的红萍,可满足2人及100 kg鱼三者共生的CELSS氧气需求。结论发酵型生化反应器与红萍养殖循环系统有机耦合的废弃物发酵处理装置,是降解废弃物、优化系统耗氧、提高物质循环闭合度的一个有效途径。
Objective To study the oxygen flow and waste fermentation disposal in controlled ecological life support system（ CELSS）,and to solve the life support problem in the development of manned space flight technology. Methods The CELSS oxygen production and supply capacity were analyzed in detail according to the oxygen flow in the crew-azolla-fish CELSS. The oxygen shortage and surplus balance capability was obtained. Results In addition to the oxygen consumption of the biodegradable waste oxidative degrading,50. 4 m^2 azolla cultivation could satisfy the oxygen demand of two crews and 100 kg fish. Conclusion Fermentational and biochemical reactions coupled with azolla cultivation circulating system can effectively degrade the waste,optimize the oxygen consumption and improve the material circulating closure.
