The invention relates to a domestic organic waste splitting decomposition reductive transformation reaction processing process, and belongs to the technical field of environmental protection. Along with rapid growth of population, cities and towns are enlarged continuously, the yield of domestic organic waste is increased day and day, environments of the cities and towns and the surroundings are seriously polluted, and bodies of surrounding residents can be seriously harmed. At present, the main domestic organic waste processing methods in China are power generation by waste combustion, pyrolysis gasification and landfill. As organic waste of the cities and towns in China is complex in ingredient and low in calorific value, auxiliary fuel needs to be added during power generation by wastecombustion and pyrolysis gasification, and therefore the processing cost is increased, hazardous substance like Dioxin is generated during running of power generation by waste combustion due to the factors of technologies, operation and the like, a large amount of land is occupied by landfill treatment, and meanwhile the atmosphere and the underground water source are seriously polluted. The domestic organic waste splitting decomposition reductive transformation reaction processing process is low in cost, harmless, minimized and recycle, the domestic organic waste is environment-friendly and high in efficiency and becomes resource matter.
