Customization of Mobile Toilets for Wuhan Parks

Customizing mobile toilets for parks in Wuhan requires comprehensive consideration of materials, structure, functional configuration, and environmental adaptability. Below are the key points:

1. Material and Structural Selection
Wuhan experiences high temperatures, heavy rainfall, and high humidity, necessitating the prioritization of corrosion-resistant and moisture-proof materials. Primary materials recommended include high-density polyethylene (HDPE) or fiberglass-reinforced plastic (FRP): HDPE is molded through rotational molding without seams, preventing rust; FRP is lightweight and strong, suitable for frequent relocation scenarios. Modular structural design enhances efficiency by decomposing walls, roofs, and chassis into independent modules for factory prefabrication and on-site assembly. The chassis should have pre-embedded sewage discharge interfaces, walls should have reserved ventilation windows and wiring channels, and connection methods can be either mortise-and-tenon fasteners (for quick assembly and disassembly) or bolt fastening (for long-term fixation). For outdoor scenarios, it is advisable to use double-layer sandwich panel boxes filled with polyurethane or rock wool for insulation, coated with an anti-UV layer on the surface to reduce condensation and aging risks.

2. Internal Component Configuration

• Flush System: Choose based on site conditions. Parks with municipal sewage networks can use direct-discharge systems; remote or water-scarce areas are recommended to use recirculating water systems with built-in biological treatment tanks for fecal degradation.
• Toilet Types: Adjust according to user demographics. Elderly groups or medical stations require the installation of handrails and non-slip floors; ordinary scenarios can opt for squat toilets to save space.
• Ventilation System: Combine natural air ducts with solar-powered exhaust fans to avoid electricity dependency. Install axial fans at the top and louvered windows at the bottom to create an “inlet-outlet” airflow. Humidity sensors trigger automatic fan start/stop to prevent the ingress of humid air.

3. Special Design Considerations for Outdoor Use

• Sewage System: Vacuum negative pressure technology is water-efficient (0.5 liters per flush), suitable for public places like parks; microbial degradation technology requires no water source but necessitates regular replacement of bacterial carriers. Storage tanks should be equipped with weighted bases to prevent floating.
• Structural Reinforcement: Use trapezoidal reinforcing ribs at stress-concentrated areas such as door hinges and roof corners. The chassis should be made of 3mm checkered steel plates with reserved pressure relief holes, and lifting rings should be embedded in I-beam skeletons.
• Rust Prevention: Apply hot-dip galvanizing (thickness ≥ 85 microns) and epoxy sealing paint for double-layer protection. Critical welds should be additionally coated with zinc-rich paint to extend service life.

4. Supplier Recommendations
