Study on O2-supply Characteristics of Azolla in Controlled Ecological Life Support System
摘要
Abstract
In this study, we try to investigate the O2-supply characteristics under manned condition in order to lay a foundation for carrying out Azolla biological component systematical and general ground simulation experiment and space application. A closed test cabin of Controlled Ecological Life Support System and Azolla wet-culturing devices were built to measure the changes of atmospheric O2-CO2 concentration inside the cabin under "Azolla-fish-men" coexisting condition. The results showed that, O2 consumption amount per unit weight of fish is 0.0805-0.0831L.kg-1.h-1, the CO2 emission amount is 0.0705-0.0736L.kg-1.h-1. Which of trial volunteers is 02 19.71L.h-1 and CO2 18.90 L.h-1 under 7000-8000lx. Artificial light, human and fish respiring and Azolla photosynthetic O2-releasing tend to achieve O2-CO2 homeostasis inside the cabin. Enhancing atmospheric CO2 concentrations in the cabin obviously promoted Azolla group net photosynthesis efficiency. This shows that Azolla has strong photosynthetic O2-release ability, which equilibrates the O2-CO2 concentration inside the cabin in favor of human survival, and then verifies the prospect of Azolla in space application.关键词
