Block chain factory method for producing gas and preparing fertilizer by twice application of solid-liquid organic wastes of household garbage

The invention relates to the fields of agricultural organic waste treatment, environmental protection and energy, and particularly relates to a block chain factory method for producing gas and preparing a fertilizer by twice application of solid-liquid organic wastes of household garbage. According to the method, a blockchain environment protection technology is adopted, household garbage, agricultural organic waste and solid waste and liquid waste are subjected to gas production and fertilizer production with the same machine in the same factory, and liquefied natural gas capable of being putinto market profit is produced firstly; and then a high-quality water-soluble organic fertilizer generated by high-temperature mineralization reaction is produced and put into agriculture, to improvesoil and improve quality of crops, so that the living ecological environment of human beings is improved. Peasants are enriched by using exchange measures, so that the aim of benefiting human beingsby using ecology is fulfill
