Large-scale Environmental Protection Mobile Toilet

The large-scale environmental protection mobile toilet is a public sanitation facility designed with new materials and water-saving technology at its core. It features modularity, environmental efficiency, and strong adaptability. A typical example is the seven-meter trailer-mounted environmental protection toilet, which measures 7 meters by 2.6 meters. It is equipped with four environmentally friendly vacuum foam squatting positions and integrates a smart management system, central air conditioning, and a microbial degradation system, making it ready for use upon arrival at the site.

1. Structure and Materials

The frame of the large-scale environmental protection mobile toilet is welded using national standard steel, ensuring structural stability. The surface is covered with color-coated steel sheets or carved panels and other corrosion-resistant and fire-resistant materials, which not only extend the service life (up to more than 20 years) but also enhance the aesthetic appeal. Its modular design supports rapid assembly and disassembly, making it suitable for temporary events, scenic spots, construction sites, and other scenarios.

2. Internal Functional Systems

1. Excreta Treatment System

   • Independent Squatting Pit Partitioned Treatment: The urine channel utilizes gravity self-flow technology to reduce water consumption; the feces channel is automatically cleaned by a piston-type scraper mechanical device, avoiding manual intervention.
   • Microbial Environmental Protection Degradation System: It employs biodegradation technology to convert excreta into harmless substances, reducing sewage discharge and meeting environmental protection requirements.
   • Dry Packing Technology: Some models adopt a waterless flushing design, where excreta is directly packed for treatment, suitable for water-scarce areas.

2. Environmental Control System

   • Central Air Conditioning: It regulates the internal temperature and humidity, enhancing user comfort.
   • Ventilation and Lighting System: Equipped with exhaust fans and energy-saving lamps, it ensures air circulation and sufficient lighting.
   • Anti-slip Floor and Automatic Flushing Toilet Bowls: These features ensure user safety and reduce odor residue.

3. Smart Management System

   • Occupied/Unoccupied Smart Public Toilet Management System: It uses sensors to monitor the usage status of toilet stalls in real-time, guiding users to quickly find available positions and improving management efficiency.

3. Technical Types and Classifications

According to the sewage treatment method, large-scale environmental protection mobile toilets can be classified into the following types:

• Water Flushing and Waterless Flushing Suction Type: They rely on water sources for flushing or reduce water consumption through vacuum suction.
• Recirculating Water Flushing Type: It adopts a water circulation system, filtering and purifying water for reuse, achieving significant water-saving effects.
• Dry Packing Type: It requires no water source at all, with excreta directly sealed and packed for subsequent treatment.

4. Standards and Adaptability

The design of the large-scale environmental protection mobile toilet complies with the GBLT18091－92 standard, meeting national norms in terms of hygiene, safety, and environmental protection. Its modular structure and diverse technical types enable it to flexibly meet the needs of different scenarios, making it an important choice for modern public sanitation facilities.
