Discussion on the application of ion exchange resin electro-regeneration technology in manned spaceflight
As an important functional material for water treatment,ion exchange resin is widely used in medicine,chemical industry,nuclear industry and other fields.Due to its high efficiency and reliability,it is also widely used in the water circulation system of China Space Station,such as urine treatment subsystem,water treatment subsystem,and electrolytic oxygen production subsystem,which effectively guarantees the normal operation of the equipment and the safe use of water resources.Considering its renewability,the development of ion exchange resin regeneration technology for manned space missions can further reduce the supply demand of long-term missions,which is of great significance for the development of manned space flight to deep space.This paper focuses on the application characteristics and research progress of three kinds of ion exchange resin electro-regeneration technology,and the potential auxiliary regeneration technologies such as thermal regeneration,biological regeneration,ultrasonic regeneration and carbon dioxide regeneration are introduced,and the application prospect analysis of ion exchange regeneration technology is given according to the application characteristics of manned spaceflight.
