Aba Prefecture Temporary Mobile Toilet

The temporary mobile toilets in Aba Prefecture are eco-friendly facilities designed to adapt to high-altitude and climate-variable regions, with their materials, structures, treatment technologies, and energy systems optimized for local environmental characteristics.

Materials and Structural Design

The wall materials are selected from metal carved panels, aluminum-plastic panels, or fiberglass-reinforced plastic panels. Metal carved panels contain polyurethane insulation layers inside to cope with the day-night temperature differences on the plateau; aluminum-plastic panels are lightweight and corrosion-resistant, facilitating transportation and installation; fiberglass-reinforced plastic panels offer high strength and excellent weather resistance, providing outstanding wind and rain protection. The structural framework adopts a lightweight steel structure to ensure transportation integrity and withstand geological instability factors. The roof is designed as a slope to facilitate the sliding of rain and snow, preventing water accumulation. The floor materials balance slip resistance, corrosion resistance, and ease of cleaning, commonly using slip-resistant aluminum panels or special composite materials.

Excreta Treatment Technologies

In response to ecological fragility, four treatment solutions are provided:

• Packaging Treatment: Excreta is encapsulated with biodegradable films to physically isolate odors, suitable for nature reserves without sewage pipe networks.
• Microbial Degradation: Organic matter is decomposed into carbon dioxide, water, and inorganic substances by thermophilic aerobic bacteria, with a nearly odorless process, suitable for tourist campsites with power supply.
• Vacuum Water-Saving Technology: Negative pressure suction is used to complete flushing with only a small amount of water, conserving water resources, especially suitable for regions where water pipes are prone to freezing in winter.
• Foam Sealing: Foaming liquid covers the toilet bowl to block odors and reduce flushing water usage, providing a visually cleaner appearance.

Thermal Insulation, Anti-Freezing, and Energy Systems

Thermal insulation design covers walls, roofs, doors, windows, and pipes: doors and windows adopt double-glazed or thickened profiles to reduce heat conduction; pipes are wrapped with electric tracing tapes and fitted with insulation sleeves to prevent freezing. The energy supply is primarily based on solar photovoltaic systems, consisting of solar panels, energy storage batteries, and controllers, meeting electricity needs at night or on cloudy days; some designs integrate small wind turbines as a supplement to ensure stable power supply.
