Baotou Mobile Toilet Production
The production and manufacturing of mobile public toilets in the Baotou area of Inner Mongolia utilize water-flush, foam-sealing, and microbial degradation as core treatment technologies, combined with modular design and weather-resistant processes to form a standardized production system adapted to the northern climate.
Treatment System Technical Pathways
The treatment systems for mobile public toilets in Baotou are divided into three categories:
- Water-flush System: This system achieves toilet flushing through integrated water and sewage tanks. The key lies in optimizing the volume of the clean water tank (usually ≥200L) and the efficiency of the high-pressure water pump, allowing single flush volumes to be controlled at 3-5L, close to the water-saving level of traditional toilets. The sewage tank needs to be equipped with a liquid level alarm device to prevent overflow.
- Foam-sealing System: This system relies on a foam generator to form a lubricating layer on the toilet surface, reducing the flushing water demand to 0.5L per flush. The core challenge is the stability of the foam liquid—the low winter temperatures in Baotou (which can reach -30°C) can easily cause the foam to break. Manufacturers solve this problem by adding antifreeze agents (such as ethylene glycol) and optimizing the formula to ensure the foam remains covered for more than 8 hours.
- Microbial Degradation System: This system utilizes aerobic microbial communities to decompose excreta, producing water vapor, carbon dioxide, and inorganic salts. The tank needs to be equipped with a heating device (to maintain a temperature of 25-40°C) and a stirring system (operating for 10 minutes every 2 hours) to promote microbial activity. This technology can extend the waste residue removal cycle to 3-6 months, but it requires continuous power supply (approximately 2kWh per day) and a professional maintenance team.
Structural and Material Processes
The wall structure uses fiberglass-reinforced plastic (FRP) or stainless steel:
- FRP is molded in one piece, lightweight (about 50kg/㎡), and has excellent thermal insulation properties (thermal conductivity ≤0.2W/(m·K)), suitable for mass production of standardized toilet compartments;
- Stainless steel (usually 304 grade) is highly corrosion-resistant and can withstand frequent flushing with chlorine-containing disinfectants, making it suitable for public places or high-humidity environments.
The main load-bearing frame uses cold-formed steel sections (such as C-sections), with nodes connected by bolts and externally wrapped with FRP or galvanized steel sheets (thickness ≥1.2mm). To cope with low winter temperatures, the exterior of the tank is equipped with a 50mm thick polyurethane insulation layer or self-regulating heating cables (power approximately 30W/m) to ensure the internal temperature remains ≥5°C.
Ventilation and Modular Design
The ventilation system adopts a top exhaust + bottom intake directional airflow design, with an exhaust volume ≥150m³/h, combined with activated carbon filtration or ultraviolet light decomposition odor removal equipment to ensure the toilet odor concentration (measured as hydrogen sulfide) ≤0.02ppm.
The production process follows modular principles: toilet compartments, treatment systems, water and electrical pipelines, and other components are prefabricated in the factory and assembled on-site using quick connectors (such as snap-fit water pipe connectors), reducing installation time to within 4 hours. Modular design also supports functional expansions, such as adding solar panels (with an average daily power generation of about 1.5kWh) or intelligent monitoring systems (real-time display of water level, microbial activity, and other parameters).
Mobile public toilets in the Baotou area achieve comprehensive performance in water conservation, cold resistance, and ease of maintenance through technological adaptation and process optimization, becoming a typical solution for public facility construction in northern cities.
