Beijing Waterless Mobile Toilet

The Beijing waterless mobile toilet is an independent ecosystem based on space compression and resource recycling, with its core being waterless fecal treatment technology.

Operational Mechanism

• Solid-Liquid Separation and Microbial Degradation Unit: Excreta is first separated into liquid (urine) and solid (feces) through a special filter. The urine enters a biochemical reaction tank, where it is decomposed by specific microbial communities into water, carbon dioxide, and inorganic salts. The treated water is used for flushing. The solid feces are dried and fermented until the moisture content is below 10%, forming a stable powder.
• Fully Automated Intelligent Control Network: Composed of sensors, controllers, and communication modules, it provides real-time monitoring and dynamic adjustment of functional units. For example, a human body sensor automatically locks the door and activates the ventilation fan. Liquid level, humidity, and odor sensors monitor the water tank level, control the heating power, and adjust the ventilation volume, respectively. Data is uploaded to a cloud platform, allowing maintenance personnel to remotely check the status and generate maintenance work orders.

Advantages and Features

• Flexible Site Selection: Only a flat ground and basic power supply are required (some models support solar power), enabling rapid deployment in parks, event venues, old neighborhoods, and other areas where the pipeline network is unavailable.
• Solving Toilet Problems at Large Events:
  • Closed Storage of Excreta: Double-layer anti-corrosion sewage storage tanks are used, with capacities designed according to the event scale. Hydrophobic materials reduce cleaning difficulty.
  • Odor Control: Biological enzyme degradants reduce ammonia production, activated carbon filters adsorb odors, and ultraviolet lamps regularly disinfect microorganisms.
  • Modular Rapid Deployment: Standard module design allows 200 units to be set up within 4 hours and quickly dismantled after the event.
  • Closed-Loop Waste Treatment: After solid-liquid separation of the waste in the storage tanks, the liquid enters the sewage treatment system, and the solid is converted into organic fertilizer. The water consumption is less than 1% of that of traditional toilets.
  • Strong Environmental Adaptability: In winter, insulation materials and electric heating tapes maintain the temperature inside the tank. In summer, the ventilation system is used for cooling and moisture prevention. Stainless steel floor drains and anti-slip floors inhibit bacterial growth.
