Mobile Environmental Toilet Project

The Mobile Environmental Toilet Project is a toilet facility project that employs environmental protection technologies and is designed to be mobile and modular. It features water conservation and resource recycling, making it suitable for various public places.

1. Definition and Characteristics
   Mobile environmental toilets achieve mobility through modular design. Their frames are welded from national standard steel, and their surfaces are covered with anti-corrosion and fire-resistant materials such as color-coated steel plates or carved panels, ensuring a service life of over 20 years. Their core advantage lies in environmental protection technologies, such as water-saving systems and resource recycling, which reduce reliance on traditional water resources.

2. Technology Types and Water-Saving Mechanisms

   • Waterless Flush Type: Does not require water supply or drainage pipes; treats excreta through physical or chemical methods.
   • Water Flush Type: When connected to pipes, employs technologies such as rainwater collection and filtration, and secondary use of hand-washing water for flushing to conserve water.
   • Foam Sealing Type: Uses foam to cover the surface of excreta, blocking odors and reducing water consumption.
   • Microbial Degradation Type: Decomposes excreta through microorganisms to achieve harmless treatment.
   • Recirculating Water Flush Type: Equipped with intermittent aerobic and anaerobic treatment units, it purifies sewage and recirculates it for flushing.
   • Dry Packing Type: Uses biodegradable plastic bags to collect excreta, automatically changing bags and centralizing treatment.
     Smart water-saving ecological toilets collect urine and hand-washing water, add special agents, and achieve a flushing effect with only 0.46 liters of water per person, significantly improving water-saving efficiency.

3. Smart Configuration and Remote Management
   Some products integrate smart systems, including bottom-level PLC data collection, 40-inch LED toilet stall monitors, and 4G remote monitoring modules, supporting mobile app control of lighting and flushing. For example, the usage status of toilet stalls can be displayed in real-time, facilitating scheduling and maintenance by operation and maintenance personnel and improving management efficiency.

4. Application Scenarios and Regulatory Support
   They cover scenarios such as temporary toilets on construction sites, toilets in scenic areas and gardens, and vehicle-mounted toilets, suitable for public places such as scenic areas, service areas, and rural areas. According to the "Chengdu Public Toilet Management Regulations," large-scale events are required to be equipped with environmental protection mobile toilets to meet temporary needs, reflecting their social value.

5. Structural Design and Material Selection
   Exterior wall materials can be selected from color-coated steel plates, metal carved panels, anti-corrosion wood, etc. The main structure is welded from national standard light steel keels, supporting overall hoisting. Standard configurations include toilet bowls, clothes hooks, exhaust fans, etc., with optional cold and warm air conditioners, air purifiers, anti-freeze systems, etc., to adapt to different climates and usage needs.

6. Historical Development
   The third public toilet revolution (from the 1990s to the end of the 20th century) promoted the transition of mobile public toilets from wood to fiberglass and polyethylene materials; the fourth public toilet revolution (at the beginning of this century) gave rise to ecological technologies such as reclaimed water reuse and solar public toilets, emphasizing pollutant self-purification and resource recycling, with mobile environmental toilets becoming an important development direction.
