Embodiment Construction

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

[0023] The sewage circulation treatment 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 fecal sewage is strengthened under the action of mechanical stirring. The mechanical stirring and pulverizing device 3 realizes its function through the vertically installed stirring blades driven by the reduction motor, and the stirring speed is controlled between 100-500rpm. At the same time, the main pollutants of fecal sewage ...

Abstract

The invention discloses an ecological toilet for flushing with circulating water. Its structure is that a high-level water tank is sequentially connected with a toilet, a stirring and crushing device, a solid-liquid separation device, an anaerobic reaction device, an aerobic reaction device, an aerobic reaction device and an ozone disinfection device through a water pipe. The device is connected, and the ozone disinfection device is connected to the high-level water tank through the water pump. The present invention has the advantages of breaking through the dependence of toilets on water and the limitation that other types of ecological toilet pollutants need to be harmlessly treated in different places; Potential defects of secondary pollution of packaging materials; improve the in-situ treatment efficiency and harmless treatment degree of feces; expand the concept and application field of ecological toilets; make full use of the rich microbial resources in excrement and strengthen its functional digestion Effect: The degree of humanized design has been improved, and the new concept of ecological sanitation unit has been updated.

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 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. . 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-deficient countries in the world. The per capita water resources are only 1 / 4 of the world's per capita water resources. The shortage and pollution of water resources have seriously affected my country's national economic construction and people's normal life. Toilet flushing water is not only an important part of domestic water, but also its sewage is one of the important sources of dom...
