Ecological sanitary public pit toilet for plateau severe cold farming and pastoral areas

Abstract

The invention relates to the technical field of sanitary public pit toilets, and particularly relates to an ecological sanitary public pit toilet for plateau severe cold farming and pastoral areas. The ecological hygiene public pit toilet for plateau severe cold farming and pastoral areas comprises toilet rooms for men and women, an excrement outlet of an excrement and urine diversity type toiletstool arranged in the toilet chamber is connected with the first excrement tank reactor chamber; a manure pit reactor chamber II is arranged on the adjacent side of the manure pit reactor chamber I; wherein an excrement passing opening and an inter-chamber flashboard are arranged between the first chamber and the second chamber of the excrement pool reactor, heat coils are arranged at the bottomsof the first chamber and the second chamber of the excrement pool reactor, phase change heat storage structures are arranged at the lower parts of the first chamber and the second chamber, and the phase change heat storage structures are provided with heat coils which are communicated with a heating medium circulating pump and a solar heat collector through water distributing and collecting devices. And the manure pit reactor chamber I and the manure pit reactor chamber II are provided with air inlet pipes, exhaust pipes and exhaust fans. And the pit toilet is powered by a self-contained wind-solar hybrid power supply system. The invention provides a sanitary public pit toilet which is suitable for plateau severe cold farming and pastoral areas, free of water supply, water drainage, powersupply and heat supply and capable of collecting and operating excrement and urine separately.

Description

technical field [0001] The invention relates to the technical field of hygienic public dry toilets, in particular to an ecological and sanitary public dry toilet in severe cold plateau farming and pastoral areas. Background technique [0002] The harmlessness of feces is the bottom line requirement for sanitary toilets to prevent and control water pollution, intestinal infectious diseases and parasitic diseases. [0003] Anaerobic digestion of feces is a treatment process that uses facultative bacteria and anaerobic bacteria to perform anaerobic biochemical reactions and decompose organic matter in feces. resource) the main link, the most widely used. [0004] The exploration of ecological dry toilets is more suitable for the upstream areas of the source of rivers and remote farming and animal husbandry poverty-stricken areas. In the cold and dry farming and pastoral areas of Northwest China, the double-urn funnel toilet with many advantages is popular; the herdsmen in Sic...

AI Technical Summary

Problems solved by technology

[0007] In the severe cold farming and pastoral areas of the plateau, the environmental conditions are special, and the feces and urine freeze for as long as 6-10 months during the slow heating period. The impact of weather and ecological dynamic factors (mainly temperature) is the most significant, and the ambient temperature required for the metabolism of fecal microorganisms cannot be maintained. , the metabolic decay or death of the microbial community, the most critical and effective anaerobic digestion of harmlessness is difficult to achieve

Coupled with the sparse population and the high cost of supporting facilities, the application of dry toilets has far-reaching significance
