Intelligent toilet based on mixing and smoldering of human and animal excreta and biomass in countryside

Abstract

The invention belongs to the technical field of harmless disposal of human and animal excreta in countryside and environmental sanitation and discloses an intelligent toilet based on mixing and smoldering of human and animal excreta and biomass in the countryside. The intelligent toilet includes a feces separation toilet body, a urea collecting vessel, a feces storage and stirring tank, a biomassstorage tank, a sand storage tank, a stirrer, a cylindrical smoldering reaction vessel, an air compressor, an electric heater and an automatic control system. A first auger is connected to the biomassstorage tank and the feces storage stirring tank; a second auger is connected to the sand storage tank and the feces storage stirring tank; a third auger is connected to the feces storage stirring tank and the cylindrical smoldering reaction vessel; an air pipe is connected to the air compressor and the cylindrical smoldering reaction vessel; a smoke pipe is connected to the cylindrical smoldering reaction vessel and the urea collecting vessel; a fourth auger is connected to the cylindrical smoldering reaction vessel and the urea collecting vessel. The intelligent toilet can achieve harmlessdisposal of the human and animal excreta in the countryside quickly, economically, safely and thoroughly and recover inorganic nutrient elements in the excreta for application as green fertilizer.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of human and animal excrement in rural areas and environmental sanitation, and more particularly relates to an intelligent toilet. Background technique [0002] Improper disposal of human and animal excrement can seriously endanger public health and health in rural areas of China. Due to the low population density and underdeveloped economy in rural areas, an expensive centralized sewage treatment system is obviously not feasible. At present, the main types of toilets used in rural areas are septic type and squat type. Both types of toilets face problems such as long accumulation of feces, rough construction, and poor management, resulting in the leakage of germs and surface water and groundwater. serious pollution. Since the water content of human and animal manure is as high as 65-85%, the treatment methods of incineration or pyrolysis need to consume a lot of energy to dry the manu...

Problems solved by technology

[0004] In addition to the above-mentioned gratifying technical indicators, the existing smoldering toilet and its design technology also have the following technical defects: (1) the system is complex and consumes a lot of water; The treatment of 90% dysentery feces is still in the research and development stage; (3) in order to realize self-sustainable smoldering, the feces have to be partially dried to reduce the water content to about 50%, and the drying pr
