A smart toilet based on the mixed smoldering of rural human and animal manure and biomass

Abstract

The invention belongs to the technical field of harmless treatment of rural human and livestock feces and environmental sanitation, and discloses an intelligent toilet based on the mixed smoldering of rural human and livestock feces and biomass, including a urine and feces separator, a urine collection container, and a feces storage and mixing box , biomass storage tank, sand storage tank, agitator, columnar smoldering reaction vessel, air compressor, electric heater and automatic control system; the first auger connects the biomass storage tank and the excrement storage mixing tank; the second auger Connect the sand storage tank and the excrement storage mixing tank; the third auger connects the excrement storage mixing tank and the columnar smoldering reaction vessel; the air pipeline connects the air compressor and the columnar smoldering reaction vessel; the flue gas pipeline connects the columnar smoldering reaction vessel and the urine liquid collection container; the fourth auger connects the columnar smoldering reaction container and the urine collection container; the invention can quickly, economically, safely and thoroughly realize the harmless treatment of human and livestock manure in rural areas, and recycle the inorganic nutrients therein as green fertilizers.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of human and livestock excrement and environmental sanitation in rural areas, and more specifically relates to an intelligent toilet. Background technique [0002] Improper disposal of human and animal waste will 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 and squatting pits. These two types of toilets are faced with 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 livestock manure is as high as 65-85%, it needs to consume a lot of energy to dry the manure by incineration or pyrolysi...

AI Technical Summary

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 process consumes a lot of energy; ( 4) The design scale is not flexible enough (10-20 people / household), and it is larger than the average population per household in rural China (about 3-5 people); (5) It is only designed for human feces, and cannot be used for poultry and livestock feces. harmless treatment; and (6) energy management is far from optimal, and the gaseous products generated by smoldering combustion have not been treated and controlled in any way
