Microbial Mobile Ecological Toilet

The microbial mobile ecological toilet is an environmentally friendly sanitation facility based on microbial decomposition technology, with solid-liquid separation as its core principle. It converts excreta into harmless substances through microbial flora, featuring water conservation, mobility, and intelligent control.

Core Working Principle
This toilet separates feces and urine for individual treatment using solid-liquid separation technology:

1. Feces Treatment: Microbial flora are used to stir, deodorize, ferment, decompose, and evaporate feces. Under suitable temperatures (some models maintain environments above 60℃ through intelligent temperature control systems), microorganisms decompose organic matter into carbon dioxide, water vapor, and a small amount of ammonia for emission, while residues are converted into organic fertilizer for resource utilization.
2. Urine Treatment: Urine is deodorized and decomposed into reclaimed water, which can be directly discharged or used for green irrigation, reducing water waste.

Key Features

1. Water Conservation and Environmental Protection: Only 70-80 kilograms of water are needed initially to activate the microbial flora, with no subsequent flushing required. Annual water savings exceed 3,000 tons (as demonstrated by the Chengdu carbon-neutral public toilet case), making it suitable for cold, water-scarce regions or areas without sewage discharge permits.
2. High Mobility: The toilet body adopts a steel-frame cement composite structure or light steel housing, offering a compact and lightweight design. It requires no underground sewage pipes or treatment systems, enabling rapid deployment at temporary venues (e.g., 13 venues at the 2022 Beijing Winter Olympics).
3. Intelligent Control: Some models are equipped with PLC control systems for constant temperature and humidity, automatic stirring, and photoelectric induction-triggered flap opening/closing. The intelligent temperature control system also provides sterilization and disinfection functions to ensure hygiene and safety.
4. Durability and Low Maintenance: With excellent thermal insulation, the steel-frame structure supports operation in environments as cold as -28℃ and has a lifespan exceeding 20 years. Annual maintenance costs are approximately 15,000 yuan, with no need for professional daily operation.

Application Value
This technology significantly reduces construction and operational costs: the construction cost per toilet unit is 100,000 yuan lower than that of traditional water toilets (Winter Olympics case). It also supports customization (e.g., electric induction, foot-pedal, or button-operated opening/closing functions) to meet diverse scenario demands. Its resource-based treatment model offers an innovative solution for the environmental protection sector.
