[0002] Climate change is a common challenge facing the world today. Developing a low-carbon economy, reducing greenhouse gas emissions, and mitigating global warming have become a global consensus. Existing rural production models, such as crop production and animal husbandry, generate large quantities of organic waste, including straw and livestock manure. These wastes are both a source of pollution and a potential source of agricultural and forestry biomass and green chemical products. If these wastes are not properly handled, they will not only pose significant risks to the environment, society, and the physical and mental health of residents, but will also hinder the full recycling of the resources they contain.

Existing rural toilets often use temporary collection devices with short lifespans, which have little impact on the recovery of feces, urine, and biomass. This can easily lead to excessive waste accumulation and delayed recycling, which can damage the ecological environment.
[0004] Therefore, it is necessary to design a rural toilet based on waste resource recycling and energy saving to solve the above technical problems. Utility Model Content

[0041] By setting the inclined glass roof 3, on sunny days, sunlight can be irradiated into the toilet body, thereby saving electricity.
[0042] The energy-saving resource recycling toilet provided by the utility model has the following working principles: when in use, the water is initially collected in the water collection tank 4 and purified by the water purification device, and then flows into the rainwater circulation tank 11 for collection, and can provide water for the wash basin 10 and the squat toilet 8, reducing the use of groundwater. At the same time, the water collected through the sewer pipe of the wash basin 10 is collected to the treatment water circulation tank 12, which can provide water for the squat toilet 8 and then flush the excrement. The flushed excrement enters the solid area through the sewer pipe of the squat toilet 8, wherein the fecal solid matter is intercepted by the filter screen 14 and the guide membrane 23, and the mixed liquid of urine and water flows through the guide membrane 23. Enter the liquid area, put biochar in the biochar storage tank 17, put enterococcus faecalis and yeast compound bacteria in the microbial tank 13, and then pile up biomass such as waste straw in the solid area, which can neutralize the nitrogen in the feces, prevent the reproduction of pathogens, and facilitate composting; the temperature and humidity in the collection box 7 are monitored by the humidity sensor 18 and the temperature sensor 19. When the temperature is insufficient, the microcontroller controls the heating rod 21 to heat it, and the biochar absorbs nitrogen, phosphorus and other elements and removes odors. The biochar after adsorption saturation can be returned to the field. In the early stage of composting fermentation, the microcontroller is used to control the temperature and humidity in the collection box 7. Control the opening and closing of the solenoid valve 22, the fan 16 and the aeration pipe 15 to ensure that there is sufficient oxygen in the collection box 7. Specifically, control the aeration device to allow oxygen to enter the collection box 7 through the aeration pipe 15 and diffuse around and at the bottom of the collection box 7. Control the fan 16 to maintain a certain speed to evenly distribute the oxygen and maintain the temperature in the box. At the same time, the decomposition of the microbial agent can kill some pathogens and parasite eggs. In the later stage of composting, as the box temperature changes and the oxygen is consumed, an anaerobic environment will gradually form in the box. The solenoid valve 22 on the exhaust hole 24 is opened, and the aeration device is closed. The electromagnetic valve 22 is located in the aeration pipe 15. At the same time, the fan 16 still maintains a certain speed to prevent the accumulation of gases such as CH4 and SO2, so that gases such as CH4 and SO2 are collected outside the box 7 through the exhaust hole 24. During anaerobic composting, the electromagnetic valve 22 located on the exhaust hole 24 is opened once every 30 minutes to avoid excessive generation of harmful gases during long-term anaerobic fermentation. When recycling waste, the closed box design can further reduce the leakage of odorous gases. The mixture of urine and water in the liquid area is deodorized and collected in the treated water circulation box 12 and can serve as a water source for the squat toilet 8.
