Embodiment 1

[0024] The mixed substrate of feces and coconut husks contains easily degradable, non-degradable and non-degradable organic matter. The degradation process of the ecological toilet is to use microorganisms to decompose and transform the degradable organic matter in the raw materials to generate CO 2 , water and heat process. Therefore, the reduction of organic matter is a direct indicator of the fermentation process. In the 33rd day, the residue of the substrate in the slope reaction tank was taken to test the organic matter content, and the test results were as follows: image 3 shown. The results showed that the organic matter content continued to decrease during the 33-day period, and finally stabilized at about 35.1%, indicating that the coconut shell shavings-based ecological toilet works well.

Embodiment 2

[0026] The carbon-nitrogen ratio of compost is an important chemical index to evaluate the degree of composting. During the composting process, microorganisms consume carbohydrates continuously, so the carbon-nitrogen ratio tends to decrease, because the carbon-nitrogen ratio of microorganisms is about 16. Theoretically, the decomposed compost should eventually tend to have a microbial cell carbon-to-nitrogen ratio of about 16. In order to investigate the change of carbon-nitrogen ratio in the non-water flushing ecological toilet with coconut shell chips as the biomass base, the substrate residues in the slope reaction tank were taken on 1, 5, 9, 13, 17, 21, 25, 29, and 33 days Carry out the carbon-nitrogen ratio test, the test results are as follows Figure 4 As shown, the final carbon-nitrogen ratio is about 14.2%.

Abstract

The invention discloses a flushing-free ecological toilet taking coconut shell crumbs as a biological matrix. The ecological toilet is composed of such parts as a feces and urine collecting pedestal pan, a slope reaction tank, a stirring device, an exhaust device and the like. According to the ecological toilet, the coconut shell crumbs are taken as the reaction matrix; and excrement is collectedunder a flushing-free condition and is fermented via aerobic microorganisms, so that the excrement is converted into odorless water, CO2 and organic fertilizer. According to the ecological toilet provided by the invention, problems of conventional flushing-type toilets which are high in flushing amount, high in sewage discharge, high in sewage processing cost and the like can be solved; in-situ excrement processing and material recycling can be implemented; and meanwhile, good utilization of coconut shells, as a common agricultural waste, is achieved, so that purposes of saving a water resource, reducing environmental pollution and achieving waste resourcing are achieved.

Description

technical field [0001] The invention belongs to the field of waste recycling, and relates to a water-free ecological toilet with coconut shell chips as biomass base. Background technique [0002] Among the more than 7 billion people in the world, about 2.4 billion people have not used sanitary toilets, and about 950 million of them are still using open-air toilets. Even in urban areas with relatively good sanitary conditions, there are still about 2 billion people whose excrement is not treated or is only simply treated in septic tanks before being discharged into the environment. Unsanitary toilet conditions, especially the unsafe discharge of excrement, black water, gray water, and yellow water cause about 1.5 million children to be infected with diseases every year around the world, and the direct economic loss is as high as 260 billion U.S. dollars every year. Although the coverage rate of toilets in my country has increased from less than 10% 20 years ago to about 80% ...
