Water-Storage Environmental-Friendly Mobile Toilet
The water-storage environmental-friendly mobile toilet is a movable public sanitation facility that combines water-storage functionality with eco-friendly design. Its core lies in achieving independent operation through built-in water-storage devices, reducing reliance on external water sources while employing water-saving or waterless technologies to minimize environmental impact.
1. Design Principles and Structural Features
Water-storage environmental-friendly mobile toilets typically include an independent water-storage system for storing flushing water or treating sewage. For example, a young man transformed a water storage barrel into a mobile toilet by splitting it in half, using the upper half as a roof and embedding toilet fixtures, a water tank, etc., in the lower half. A drainage pipe was installed at the bottom to connect to a sewage barrel, forming a complete water-storage-sewage discharge cycle. Some high-end models are also equipped with small water-storage devices (such as plastic buckets) and accessories like bath heaters and washbasins to enhance convenience.
Another type employs vacuum self-priming sewage discharge technology, featuring built-in water and sewage storage tanks that operate without electricity. Its vacuum squat toilet uses negative pressure to suction waste into the sewage tank while automatically sensing and releasing water for flushing. The water tank can support multiple uses, making it suitable for scenarios without municipal water supply.
2. Technological Approaches and Environmental Advantages
- Water-saving technology: Some mobile toilets collect hand-washing water and add special agents to achieve a flushing effect with only 0.46 liters of water per person, significantly reducing water consumption.
- Waterless/low-water treatment: Technologies like vacuum self-priming and foam sealing reduce water usage through physical means, even enabling waterless flushing to prevent sewage discharge and environmental pollution.
- Material durability: The frame is welded from national standard steel, covered with anti-corrosion and fire-resistant materials like color-coated steel plates or carved panels, ensuring a service life of over 20 years and reducing waste from frequent replacements.
3. Application Scenarios and Industrial Chain Support
Water-storage environmental-friendly mobile toilets are widely used in public places such as scenic spots, service areas, and rural areas, particularly suitable for temporary events, post-disaster reconstruction, or water-scarce regions. They come in various forms, including trailer-mounted, box-type substation cabinet-style, and stainless steel kiosk-style, supporting both vehicle-mounted and fixed installations. The industrial chain covers over 20 production enterprises in Liaoning, Shanghai, Hebei, etc., offering solutions like prefabricated and eco-friendly water-saving models to meet diverse needs.
4. Standards and Safety
The mobile toilet is equipped with an independent toilet pit partitioning system inside. The urine channel utilizes gravity flow, while the feces channel is cleaned by a piston-type scraper mechanical device. It also features non-slip floors, automatic flushing toilet bowls, and ventilation and lighting systems, complying with the GBLT18091－92 standard. Some models are also equipped with emergency call buttons to enhance safety.
