Abstract

The study addresses the possible ways of involving gaseous products produced by “wet” incineration of human wastes mixed with H 2O 2 in an alternating electric field in the cycling of the physical model of a bio-technical life support system (BTLSS). The resulting gas mixture contains CO 2 and O 2, which are easily involved in the cycling in the closed ecosystem, and NH 3, which is unacceptable in the atmosphere of the BTLSS. NH 3 fixation has been proposed, which is followed by nitrification and involvement of the resulting products in the mass exchange of the closed system. Experiments have been performed to show that plants can be grown in the atmosphere resulting from the closing of the gas loop that includes a physicochemical installation and a growth chamber with plants representing the phototrophic compartment of the BTLSS. The results of the study suggest the conclusion that the proposed method of organic waste oxidation can be a useful tool in creating a physical model of a closed-loop integrated BTLSS.
