Mobile Flushing Environmental Toilet Design
The design of mobile flushing environmental toilets encompasses multiple aspects, including structural framework, materials, water treatment, water conservation, odor control, humanized design, and intelligent systems.
Structural Framework: It adopts a steel-welded frame structure, with the bottom welded using channel steel or I-beams and the columns made of square steel to meet lifting requirements, facilitating easy movement and installation. This design ensures the overall structural stability while considering flexibility and reusability.
Material Selection: Wall materials include color-coated steel plates, metal carved panels, aluminum-plastic panels, and anticorrosive wood, which possess anticorrosive and fire-resistant properties and can operate normally within a temperature range of -20℃ to 50℃. These materials are not only durable but also adaptable to different climatic conditions, extending the toilet's service life.
Water Treatment System: It does not rely on a fixed pipe network and treats waste through a combination of physical and biochemical methods. Solid waste undergoes solid-liquid separation and enters a sealed container, while the liquid portion flows into an integrated biological reaction unit where specific microorganisms decompose organic matter, reducing chemical oxygen demand and ammonia nitrogen content. Some systems can purify the treated liquid to a level suitable for non-potable flushing, achieving resource recycling.
Water Conservation Design: It employs flow control technologies, such as vacuum suction or high-pressure air-mist flushing, to complete cleaning with minimal water. Some systems introduce the concept of a closed-loop water cycle, where flushing water is reused after multi-stage purification, with new water added only in case of evaporation or loss. For example, certain mobile toilets achieve a flushing effect of only 0.46 liters per person by automatically collecting hand-washing water and adding a special agent.
Odor Control: It is achieved by intervening in the gas generation and diffusion paths throughout the process. The storage tank below the toilet maintains a negative pressure state and is immediately injected with enzyme and probiotic decomposers to inhibit the generation of malodorous substances such as ammonia and hydrogen sulfide. The toilet interior is equipped with an active ventilation device that filters the air before exhausting it, effectively removing odor components.
Humanized Design: The internal layout is calculated based on ergonomics to ensure that actions such as turning around and placing items can be completed within the limited space. Handrails, flush panels, and hooks all have specific parameter standards; lighting uses soft LED sources paired with motion sensors; and the ventilation fan noise is controlled below forty decibels. For special populations, the entrance ramp of barrier-free toilets has a slope of no more than 1:12, the internal clear space diameter is no less than 1.5 meters, the height of the hand-washing basin can be electrically adjusted, and an emergency call button is provided.
Intelligent Systems: Some toilets are equipped with a bottom-layer PLC data acquisition system, a 40-inch LED toilet stall monitor, and a 4G remote monitoring module, supporting remote control of lighting and flushing systems via a mobile app, enhancing management efficiency and user experience.
