Production method and equipment for conversion of human faeces into fertilizer and fertilizer produced thereby

Abstract

The invention relates to a production method and equipment for conversion of human faeces into a fertilizer and the fertilizer produced thereby. The method comprises the following steps: A, extracting biogas in a septic tank by an extraction machine, using solid and liquid faeces in the septic tank as original slurry; B, filtering the original slurry by a filtering device to remove debris to obtain preliminary faece slurry; C, adding a desiccant into the preliminary faece slurry to stir for mixing in a stirrer to obtain half-dry faece slag; D, drying the biogas by a gas water separation device; E, burning the dried biogas to use the heat of biogas combustion to heat and evaporate the half-dry faece slag obtained by the step C in an evaporation device to obtian dry faece slag. The production method and equipment for conversion of the human faeces into the fertilizer has the advantages of saving resources and reducing pollution, and has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to a production method and equipment for converting human excrement into fertilizer and the fertilizer produced therefrom. Background technique [0002] A large amount of human feces are produced every day in the city, and human feces contain a large number of germs, such as E. Human feces contain a large amount of organic matter, which is also a resource of great use value. After treatment, human feces can be made into high-quality organic fertilizers and other useful products. Disposal of urban human feces is an urgent problem at present, and it is also a technical problem. The implementation of harmless and resourceful feces, the comprehensive improvement of the urban environment, the creation of a sanitary city, and the construction of ecological agriculture have great significance and good economic and social benefits. . At present, the harmless treatment rate of human feces in cities in our country is very low. Most of the...

Problems solved by technology

At present, the harmless treatment rate of human feces in cities in our country is very low. Most of the human feces in cities are discharged into septic tanks through sewers as waste and wastewater, and then sucked out of the septic tanks by fecal suction trucks, and transported to the outside of the city to stay away from life. With the rapid increase of urban population, there are more and more human feces. Not only can the septic tank not hold it, but it is also difficult to find a place to bury it in the distance outside the city. This method of dealing with human feces is a very A circular vicious system wastes manpower, material resources, wastes resources, and pollutes the environment
