Abstract

The invention discloses a public toilet capable of treating and recycling excrement and urine sewage of the public toilet based on a soil infiltration technology, and belongs to the field of sewage treatment systems and technical methods. The public toilet is composed of a soil infiltration system, a recycling system and a public toilet system. The soil infiltration system is composed of a water distribution area, a soil infiltration area and a water collection area; the soil infiltration area comprises a soil layer and vegetation planted on the soil layer; the water distribution area comprises a water distribution channel and a plurality of water distribution pipes communicated into the water distribution channel; the water collection area comprises a water collection channel and a watercollection pipe; the public toilet system is composed of a public toilet, a septic tank and an adjusting tank. The recycling system is composed of a disinfection tank and a reuse water tank, a downcomer of the reuse water tank is communicated with an inlet pipe of the disinfection tank, and a water outlet pipe of the disinfection tank is communicated with a water inlet pipe of the public toilet through a disinfection pump. According to the disclosed public toilet, a soil-microorganism-plant combined action and a self-regulation mechanism are brought into full play, the purposes of convenientlyand efficiently treating urban public toilet sewage and recycling water resources are achieved, and meanwhile, the landscape and greening of cities and towns can be enhanced.

Description

technical field [0001] The invention belongs to the field of sewage treatment systems and technical methods, and relates to a green public toilet system that uses soil-microbe-plants to comprehensively purify feces and urine and sewage in public toilets such as villages, towns, scenic spots, and expressway service areas, and realize reuse for flushing after the treatment reaches the standard . Background technique [0002] In recent years, with the rapid development of my country's economy and society, people's living standards have improved significantly, and a large number of public toilets have brought convenience to people's daily life. At the same time, a large amount of excrement and sewage are produced. The discharge of urine and sewage into the external environment has brought serious pollution. Therefore, how to conveniently and efficiently treat the fecal and urine sewage from public toilets in villages, towns, scenic spots, and expressway service areas that canno...
