Homemade Mobile Toilet Vehicle

For making a homemade mobile toilet vehicle, you can refer to the following methods and choose the appropriate plan based on your needs and technical conditions:

I. Modular Vehicle-mounted Mobile Toilet (Professional Plan) This plan is based on modular design, with core components including a urine-feces separation system, decomposition bucket, urine storage tank, liquid seal device, and ventilation system. The urinal is directly connected to the urine storage tank via pipes, using gravity for urine collection. The fecal outlet is connected to the decomposition bucket, reducing fecal volume and odor through microbial decomposition or chemical treatment. A fecal collection device is installed at the bottom of the toilet body, with an exhaust pipe extending to the top and equipped with an exhaust fan to create negative pressure ventilation and prevent gas retention. The liquid seal device uses a small amount of liquid to isolate gas backflow in the pipes, enabling waterless flushing and pollution-free discharge. This plan requires professional design and is suitable for scenarios with high environmental protection and functionality requirements.

II. Waste Material Renovation Plan (Folk Simple Version)

1. Tile Base + Toilet Renovation:

   • Use discarded tiles to cut into a base, with universal wheels installed at the bottom for mobility.
   • Fix the toilet with cement and connect a sewage hose to an external collection container (such as a plastic bucket).
   • Regular cleaning of the collection container is required, suitable for temporary or low-frequency use scenarios.

2. Water Storage Tank Space Renovation:

   • Stack multiple water storage tanks to form an enclosed space, cutting openings to install a toilet and sink.
   • The drainage system is connected to an external sewage tank via PVC pipes, with ventilation openings reserved to prevent odor accumulation.
   • The advantage is easy access to materials, but the space's airtightness and stability require focused testing.

III. PVC Pipe Assembly Simple Toilet (Ultra-low-cost Version)

• Assemble PVC pipes into a base frame, lay wooden boards on top as the toilet seat, and add handrails on both sides to improve safety.
• Hang a plastic bucket at the bottom as a fecal collection container, which needs to be replaced and disinfected regularly.
• Suitable for emergencies or temporary needs, but lacks ventilation and deodorization functions, requiring other measures to improve the user experience.

Key Considerations:

• Environmental Compliance: If used in public areas, ensure fecal treatment complies with local environmental protection standards and avoid direct discharge.
• Ventilation Design: All plans must prioritize solving odor issues, which can be optimized by adding exhaust fans, activated carbon filters, or liquid seal devices.
• Stability and Safety: The mobile structure needs reinforcement to prevent tipping; electrical components (such as exhaust fans) require waterproofing.
• Material Selection: Prioritize the use of corrosion-resistant and easy-to-clean materials (such as stainless steel, PVC) to extend service life.
