Dongfang Foam Blocking Mobile Toilet

The Dongfang foam blocking mobile toilet is a mobile sanitation facility that achieves efficient water conservation, odor prevention, and environmental protection through foam technology. Its core principles, technical features, and application scenarios are as follows:

1. Water Conservation and Odor Prevention Technology
This toilet uses a foaming agent instead of traditional flushing, requiring only 0.04 liters of water per use, achieving a water conservation rate of 98%. Its odor prevention mechanism is realized through a triple design:

• Physical isolation: The foaming device mixes liquid and air in a specific ratio to generate fine microbubbles that cover the surface of the excretion channel, forming a flexible barrier to block odor diffusion;
• Secondary sealing: The sewage outlet is equipped with a weighted baffle that automatically closes after the excreta passes through, preventing gas backflow;
• Biological decomposition: Microorganisms in the fecal storage tank decompose organic matter, further reducing the concentration of odor substances such as ammonia. The measured ammonia concentration in the toilet can be reduced to below 0.1 ppm.

2. Core Performance Advantages

• Extreme environmental adaptability: The modular design supports operation in extreme temperatures ranging from -40°C to 50°C, and it can work stably at an altitude of 5000 meters or under conditions of a Level 9 typhoon, with an operating cost as low as 0.02 yuan per person-time;
• Self-cleaning ability: When new foam is generated, it pushes the old foam carrying impurities along the pipeline, achieving automatic cleaning and reducing the frequency of manual maintenance;
• Intelligent management system: A microcomputer automatically monitors the foam residue, starts the crushing device at regular intervals to prevent blockage, and is equipped with voice-activated lighting. The maintenance cost is only 5 yuan worth of foaming agent and 2 kilowatt-hours of electricity per month;
• Environmental protection closed loop: After biochemical treatment of feces, the sediment liquid infiltrates into the soil through capillary pipes as plant nutrients. A single device can reduce carbon dioxide emissions by approximately 1.2 tons per year.

3. Typical Application Scenarios
This technology has been widely applied in conventional scenarios such as urban streets, scenic spots, and construction sites, and has performed outstandingly in extreme environments. For example:

• Stations along the Qinghai-Tibet Railway utilize its earthquake resistance of up to Magnitude 7 to provide stable services for travelers;
• Antarctic research stations have achieved zero waste discharge through this system, solving environmental protection problems in polar regions.
  Its structure is simple, with core components including a foaming liquid storage tank, an air pump, a mixing generator, and a control module. Daily maintenance only requires regular replenishment of the foaming raw liquid and inspection of the air pump status.
