Mobile Toilet Design

Mobile toilet designs come in various forms, with common types and their characteristics as follows:

I. Portable Toilets Made from Modified Water Storage Tanks
This design uses a water storage tank as the core material, achieving functional integration through structural modifications. Specific steps include: splitting the tank vertically into two halves, fixing universal wheels at the bottom for mobility; increasing the tank height with wooden strips to accommodate sanitary fixtures, cutting an opening on the side and installing a sponge-strip door frame with plastic soft-panel walls; covering the top with the split upper half of the tank as a roof, and applying white waterproof paint to enhance aesthetics. Internal configurations include: drilling a hole at the bottom of the tank to install a drain pipe forming a floor drain, connecting a small water storage device and a bath heater system on the side, diverting the inlet pipe through a tee to the shower and sink, using a tank-flush toilet fixed at the bottom, and connecting the drain pipe to an independent sewage tank. This design is cost-effective but requires regular cleaning of the sewage tank, suitable for temporary or low-frequency use scenarios.

II. Mobile Bathroom Units with Wet-Dry Separation
This design adopts a standardized modular structure, typically measuring 2 meters wide and 3 meters long, with a pure white exterior and an aluminum alloy glass single door to enhance transparency. Functional zoning is clear: an external sink and mirror, and an internal separate shower and toilet area, achieving wet-dry separation with glass partitions. Materials include lightweight high-strength alloy frames and waterproof panels, with adjustable feet at the bottom for stability, relying on lifting or towing devices for movement. This design is suitable for medium-to-high-frequency use scenarios but requires connection to municipal water supply and sewage systems, with higher site requirements.

III. Design Principles Classified by Structure and Mobility

1. Structural Forms: Monolithic mobile toilets use an integrated frame, suitable for independent deployment; composite mobile toilets are assembled from multiple modules, allowing flexible expansion of functional areas.
2. Mobility Methods: Lifting types rely on lifting equipment, handling types require manual or small machinery, powered types are equipped with engines for autonomous movement, and towed types are transported by牵引车 (towing vehicles).
3. Sewage Treatment: Water-flush types require配套化粪池 (supporting septic tanks) or municipal sewage networks; waterless suction types collect feces with vacuum pumps; recirculating water-flush types purify wastewater with membrane bioreactors; dry packing types use biodegradable bags for storage, requiring no water source.

IV. Core Design Principles

1. Lightweight and Durability: Prioritize lightweight materials like aluminum alloy and fiberglass, controlling the overall weight to no more than 3 tons for easy transportation.
2. Environmental Friendliness: Use water-saving fixtures (e.g., dual-flush toilets), equip with solar power systems, and ensure feces treatment meets harmless standards.
3. Humanized Design: Maintain an internal clear height of no less than 2.2 meters, aisles width ≥ 0.9 meters, and configure barrier-free facilities and ventilation systems.

V. Special Material Application Cases
Some high-end designs use aluminum checkered plates as flooring materials, enhancing safety with their slip-resistant and wear-resistant properties; stone-patterned PVC panels are used for wall decoration, balancing aesthetics and waterproofing. Such designs are often used in scenic spots, exhibitions, and other scenarios with high image requirements.
