One kind condensing water treatment technology based on multistage film process manned spacecraft plant cabin

The present invention relates to space flight condensation water recovery and use technical fields, more particularly to a kind of multistage film process manned spacecraft plant cabin that is based on to condense water treatment technology.The present invention provides one kind and condensing water treatment technology based on multistage film process manned spacecraft plant cabin, includes the following steps：A, condensed water leading portion uses membrane bioreactor+membrane aerated bioreactor（MBR+MABR）Technology degrades to condensation Organic substance in water and ammonia nitrogen by microorganism under aerobic environment；B, the water outlet of leading portion MBR enters water tank, enters back into stage casing NF membrane and is retained, and the water outlet of a part of NF membrane enters reverse osmosis membrane, in water remaining inorganic salts and organic matter further removed；C, drinking water is made by back segment ion exchange resin, the disinfection of poly- iodine, mineralising, ultraviolet disinfection in the water outlet of reverse osmosis membrane.The present invention utilizes regeneration of the new process realization to condensed water highly effective and safe low energy consumption using bioanalysis MBR+MABR as core, in conjunction with nanofiltration reverse osmosis membrane and guarantee technique.
