Description
Technical field
The present invention relates to a kind of urine purifying device.
Background technology
The mankind will be implemented in the long-time flight of the ground external space or outside celestial body set up the base and live for a long time, should possess basic life condition, just must enough O be provided to the spacefarer
2, food, water and other essential material, and scavenging, refuse and waste water.Controlled ecological life support system (Controlled Ecological Life Support System is called for short CELSS) is state-of-the-art in the world at present closed loop life support technology.The CELSS system should not need ground to carry out supply, and itself carbon, oxygen and water can form an independence, complete closed cycle.With water is example, and cosmonaut's urine can collect, after purifying treatment, and will be as cosmonaut's tap water.(National Aeronautics and Space Administration reveals that NASA) it is costly in the space station, regularly to transport tap water, and the cost of one glass of water is developed water circulating apparatus then up to 3000 dollars according to US National Aeronautics and Space Administration.In May, 2010, expensive about 2.5 hundred million dollars of NASA, the equipment of developing is applied in international space station finally, and the cosmonaut has drunk " the space recirculated water " that forms via purifications such as urines in standing.This equipment can be collected airborne moisture in cosmonaut's urine, sweat and the station.Be stored in after these liquid are collected in the drum, absorb whole water vapour by equipment again after the heated and boiled, remaining residue just is dropped.Equipment operation 6h can generate the 22L tap water, supplies 6 cosmonaut to use.
CELSS is applied to before the space mission, must carries out the broad research of controlled condition on earth, to have reduced cost, danger and logistic implications in the space experiment.The research approach of the space life support system of each main spacefaring nation of the world is more similar, all is first ground rear space, promptly earlier sets up closed circulation system on ground, carries out the CELSS simulated experiment, again to spatial development.Red duckweed growth and breeding speed is high, the photosynthetic O of putting
2Strong with the purifying water body ability, nutritive value is abundant, is suitable as salad type vegetables, particularly can multilayer culture, and the green area of unit space is very big, is expected as the biologic components among the CELSS of space, for the spacefarer provides O
2And fresh vegetables, and remove C O
2Etc. objectionable impurities.The manned test-results in CELSS ground that is made up of controlled airtight experimental cabin red duckweed and fish etc. shows that people's respiration and the photosynthesis of red duckweed complement each other, cabin atmosphere O
2-C O
2Concentration tends to balance; Red duckweed can also be improved the DO content in the circulating water body, and NH3-N and TP are all had tangible removal effect.Therefore, be necessary to study superpower plant extraction and the decontamination water purifying characteristic that red duckweed has, in conjunction with Ti O
2Photocatalysis oxidation technique, the development urine purifying device is for man-in-loop simulation test in CELSS ground provides experimental prototype.The present invention is to the development of following industrialized agriculture, and especially to setting up the base that hangs up one's hat on the superior planets, setting up sealing and circulating type space farm etc. has reference value.
Along with fast development of national economy, living standards of the people improve constantly, and various agricultural chemicals, petrochemicals are widely used, and water surrounding has received quite serious pollution, particularly organic contamination, has become a big focus of whole society's common concern at present.For addressing this problem, control the action by governments such as using of pollutent and discharging except that the measure of adopting except that strictness, need the water treatment method of efficient, simple, the inexpensive non-secondary pollution again of research badly.Drink water purifying method provided by the invention and treatment facility after further investigation and industrialization development, will have good market outlook and commercial value.
