Flushing-free excrement and urine separating collecting and treatment system of public washroom

Abstract

Provided is a flushing-free excrement and urine separating collecting and treatment system of a public washroom. A urine drainage pipe and an excrement discharge pipe separated from the urine drainage pipe are arranged in the public washroom and communicated with a urine collecting container and an excrement collecting container, the tops of the containers are communicated with an air drainage pipe, and an excrement-urine separation toilet stool comprises a bag storage box, a bag containing mechanism and an odor separating plate opening mechanism. Stacked excrement bags are stored in the bag storage box, the side wall of an inlet of an excrement channel is provided with a transversely-arranged bag hanging groove, the excrement bag on the innermost side is provided with the bag containing mechanism, and the excrement bag on the innermost side falls off through a chute and is arranged in the bag hanging groove. An odor separating plate controlled by a bag falling switch is arranged at the bottom of the excrement channel, and the bag falling switch is controlled to enable the excrement bags to slide into the collecting container after defecating. According to the system, water resources are saved, environmental friendliness is achieved, the problems of toilet deodorization and excrement falling opening contamination are solved, the treatment and utilization efficiency of excrement and urine organic fertilizer resources is greatly improved, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the design and use of public toilets or the technology of collecting and utilizing excrement and urine, in particular to a system for the separation, collection, treatment and resource utilization of excrement and urine without water flushing in public toilets, which belongs to the technical fields of sanitation, environmental protection and agricultural ecology. Background technique [0002] The water flush toilets commonly used in public toilets have serious disadvantages: first, a large amount of water resources are wasted; second, the water flush toilets need to be equipped with a large septic tank space, which is not only troublesome to deal with, but also easy to cause air pollution; The third is that the feces resource utilization of the squatting toilet with water flushing is more complicated and difficult than that of the toilet without flushing and separation of excrement and urine. With the continuous improvement of ...

AI Technical Summary

Problems solved by technology

However, the water flush toilets and public toilets that are commonly used now not only make human excrement and urine lose their excellent use value, but also cause a lot of waste of water resources and environmental pollution

[0004] At present, although some rural toilets also use a non-flush feces and urine separation toilet, there are still problems in the use of this toilet that the excrement outlet is easy to pollute, the feces storage bucket is not sealed, the deodorization is not thorough, and the subsequent feces cleaning, fermentation, etc. Outstanding issues such as handling and shipping hassle

[0005] Importantly, there is currently no systematic technical method for the separation, collection, treatment and resource utilization of waste and urine in public toilets
