Microbial-plant filters (artificial marshes) for treating domestic sewage and industrial wastewater

摘要

The treatment of domestic sewage and removal of hazardous chemicals from contaminated water is a problem confronting communities and cities throughout the U.S. and other countries. A promising means of such wastewater treatment has been developed by NASA in south Mississippi. Attempts were made to manipulate and optimize the natural biological processes involving the symbiotic relationship between certain plants and microorganisms for space applications. A great deal of success has been achieved in developing a bioregenerating life support system that has shown potential for future space stations. That success is detailed.
