Embodiment Construction

[0022] As shown in the figure, the circulating water flushing eco-toilet designed by the present invention includes: 1-high-level water tank, 2-toilet, 3-agitating and crushing device, 4-solid-liquid separation device, 5-anaerobic reaction device, 6-combination Oxygen reaction device, 7-aerobic reaction device, 8-ozone disinfection device and 9-filter drying device.

[0023] The sewage recycling method is as follows: first, the circulating water stored in the high-level water tank 1 enters the mechanical stirring and crushing device 3 in the biological treatment unit of the ecological toilet through the toilet 2, and the crushing effect of the fecal sewage is strengthened under the action of mechanical stirring. The mechanical stirring and pulverizing device 3 realizes its function through a vertically installed stirring blade driven by a geared motor, and the stirring speed is controlled between 100-500 rpm. At the same time, the main pollutants of fecal sewage, including plant f...

Abstract

The invention discloses a circulating water flushing ecological toilet and sewage treatment method thereof. The high-position water tank orderly connects to the latrine, grinder-mixer, solid and liquid separator, anaerobic reacting device, facultative reacting device, aerobic reacting device and ozone disinfection device. The ozone disinfection device connects to the high-position water tank by water pump. The invention breaks the localization that the toilet depends on the water and the ecological toilet contaminant is treated elsewhere, conquers the secondary pollution of the transporting, collecting and packing materials for ecological no water toilet, improves the efficiency of the dejection treatment in situ and innocuous treatment degree, fully applies the abundant microbe resource in the dejection.

Description

1. Technical Field [0001] The invention belongs to a sewage treatment and reuse device, in particular to a circulating water flushing ecological toilet for treating fecal sewage. 2. Background technology [0002] According to relevant statistics from the United Nations, there are currently about 130 million people in the world who do not have access to safe drinking water and 2.6 billion people do not have access to safe sanitation facilities. The main reason for this is the serious shortage of water resources, which is becoming more and more serious. . Finding a fundamental solution to the water crisis is one of the most challenging tasks facing the international community. my country is one of the water-scarce countries in the world, and the per capita water resources are only 1 / 4 of the world’s per capita water resources. The shortage of water resources and pollution problems have seriously affected my country’s national economic construction and people’s normal lives. Toilet ...
