摘要：

The closed ecological life support system (CELSS) is an important technology in space development. We performed fundamental experiments on a small CELSS with consisted of a carp-artificial gill-chlorella system. The three-layer filtration and adsorption system with nonwoven fabrics, activated carbon and zeolite was found to be effective in treating water in a fish habitation vessel. The overall mass transfer coefficient of an artificial gill was estimated for actual liquid by the reported method for a demineralized water system. Also, a gill consisting of hydrophobic microporous membrane was ascertained to have long durability. The O2 concentration in the system increased continuously, because the ratio of the carp respiration quotient to the chlorella assimilation quotient was larger than 1. It was also found that the behavior of these dissolved gases are represented by the mathematical model proposed
