Biological Bacteria-Degrading Mobile Toilet

The biological bacteria-degrading mobile toilet is an environmentally friendly sanitation facility that utilizes microbial decomposition technology to achieve in-situ harmless treatment of excreta. It features odorlessness, water conservation, pollution-free operation, ease of mobility, and simple maintenance.

Working Principle and Core Advantages

This toilet employs feces-urine separation and microbial degradation technologies to convert excreta into carbon dioxide, water vapor, a small amount of ammonia, and non-toxic, odorless organic fertilizer. Its core advantage lies in its ability to operate independently without connecting to water supply and drainage networks, making it particularly suitable for public facilities and organic waste treatment areas. For example, the fermentation tank is equipped with microbial strains and a stirrer, achieving mixed degradation of excreta through constant-temperature heating (approximately 800W) and mechanical transmission. It consumes only 3-5 kWh of electricity per day, with treated gases discharged in compliance with standards and residues directly usable as organic fertilizer.

Product Feature Analysis

1. Odorlessness: Microorganisms effectively inhibit odor production by decomposing organic matter in excreta, improving the user experience.
2. Water and Energy Conservation: Featuring a waterless flushing design, it triggers the opening and closing of movable baffles through photoelectric induction, eliminating the need for water for flushing and consuming low daily electricity, suitable for water-scarce or limited power supply scenarios.
3. Pollution-Free Discharge: The treatment process generates minimal pollutants, with residues converted into organic fertilizer, achieving resource recycling.
4. Ease of Mobility and Installation: Compact in size, it requires no laying of water supply and drainage pipes, enabling rapid deployment in scenic spots, alpine regions, or temporary event venues.
5. Simple Maintenance: Daily operation requires no professional personnel. Microbial strains are replaced every 3-6 months, with the second-generation product adopting compressed strains for easy carrying and extended service life.

Application Examples and Technical Details

• Biodegradable Toilet: The motor automatically stirs excreta, requiring cleaning every 1-2 months. The second-generation product features smaller strain volumes for long-term backup.
• Public Area Applications: It has been installed in venues such as the Beijing Olympic Games and the Badaling Great Wall, with 13 venues at the 2022 Beijing Winter Olympics adopting this technology for eco-toilet construction.
• Technical Parameters: The fermentation tank is equipped with a spiral double-auger stirring structure, accelerating degradation through constant-temperature control, ensuring high treatment efficiency and stability.

This technology achieves ecological treatment of excreta through microbial metabolism, combining environmental protection with practicality, representing a significant step towards green and sustainable development in modern sanitation facilities.
