According to reports, the "three-phase internal circulation biogas digester" is a new type of biogas digester, which uses straw as the main fermentation raw material, adopts biochemical reaction in the same biogas digester, causes gas, solid and liquid three-phase self-circulation, and adds a biocatalyst to make aerobic, anaerobic and facultative anaerobic microorganisms participate in life activities at the same time, and basically converts the fermentation raw material into CH4 (methane)-based combustible gas. This achievement is an innovation of traditional biogas digesters, which changes the limitation that biogas raw materials can only use human and animal manure, organically combines economic benefits, social benefits and ecological benefits, improves the ecological utilization value of rural areas, reduces rural pollution and greatly improves the gas production rate of biogas digesters in winter.
In addition, it is reported that Fu was specially hired as a researcher by the Institute of Solid Waste and Sewage Treatment of Beijing Zhongtian Institute of Environmental Science and Technology, and signed a tripartite agreement with a technology company in Jiangsu to apply for "a cultivation method of biogas-producing biological strains based on Fu's new biogas technology" and apply for a utility model patent to speed up its popularization and application.
However, it is not clear why such advanced and breakthrough biogas technology has not caused a sensation in the industry, and at the same time it has been widely promoted in China.
