Structure of Plastic Environmental Protection Mobile Toilet
The structure of a plastic environmental protection mobile toilet typically includes core components such as a frame and outer shell, walls and roof, sanitary ware, sewage treatment system, mobile device, auxiliary facilities, and water-saving system. Here is a detailed explanation:

The frame and outer shell serve as the foundational support structure of the mobile toilet. The frame is mostly welded using national standard steel to ensure overall strength and stability; the outer shell is covered with anti-corrosion and fire-resistant materials such as color-coated steel plates, metal carved plates, and stainless steel plates. Some designs adopt an integrated outer shell to reinforce the chassis, further enhancing structural stability.
The walls and roof need to balance functionality and durability. Wall materials are usually color-coated steel plates or metal carved plates to meet heat insulation and moisture-proof requirements; the roof design must be waterproof and reduce indoor temperature fluctuations through heat insulation layers or special materials to ensure user comfort.
Sanitary ware is a core functional component. The independent toilet pit partition treatment system achieves cleanliness through gravity self-flow (urine channel) or piston-type scraper mechanical devices (feces channel); anti-slip floors and automatic flushing toilet bowls enhance safety and convenience; some high-end models use vacuum squat toilets, utilizing air pressure flushing technology to significantly save water.
The sewage treatment system is divided into three categories based on technical routes:
- Water-flush and non-water-flush suction type: Connected to a fecal sewage storage tank or external disposal device through pipelines for regular cleaning;
- Circulating water-flush type: Equipped with intermittent aerobic and anaerobic treatment devices, adding biological bacteria to accelerate decomposition. The treated water is recycled for flushing, achieving efficient water resource utilization;
- Dry-packing type: Excrement is received by biodegradable plastic bags, automatically replaced and collected after use, avoiding sewage generation.
The mobile device provides flexibility to the toilet. Universal wheels, lifting structures, or towing devices support overall transportation and rapid deployment, adapting to scenarios such as temporary events and disaster relief.
Auxiliary facilities enhance the user experience. Standard configurations include coat hooks, vanity mirrors, waste bins, lighting fixtures, exhaust fans, door locks, and occupancy indicators; optional configurations such as heating and cooling air conditioners, air purifiers, anti-freeze systems, and sinks can be customized for different climates and usage scenarios.
The water-saving system reduces consumption through technological optimization. It automatically collects hand-washing water and adds special agents to achieve low-volume flushing of 0.46 to 1.5 liters per person, significantly reducing water waste.
For a simple mobile toilet retrofitted from waste plastic buckets, the structure focuses more on temporariness and low cost: wooden boards with universal wheels serve as the mobile base, wooden strips fix the door frame, aluminum plates act as partitions, plastic buckets serve as sewage storage containers, and are connected to floor drains, valves, and sprinklers through pipelines. This design has lower functional integrity but is suitable for emergency scenarios or conditions with limited resources.
