Single Portable Toilet

A single portable toilet is a facility that can be moved as a whole and provides public toilet services, suitable for both fixed and temporary demand locations.

I. Basic Components A single portable toilet typically consists of core components such as a fecal sewage storage tank (or disposal unit), flooring, sanitary ware, walls, washing equipment, a water tank, a roof, and a mobile unit. These components work together to ensure the basic functionality and mobility of the toilet. For example, the fecal sewage storage tank is used to collect excreta, preventing direct discharge from polluting the environment; the mobile unit gives the toilet the ability to be relocated as a whole, adapting to different scenarios.

II. Structural Classification According to the structural form, portable toilets can be divided into two types: single-unit structures and composite structures. Single-unit structure toilets are usually independent units with a simple structure and easy installation, suitable for temporary events or small-scale venues; composite structure toilets are composed of multiple modules, offering more comprehensive functions and greater scalability, making them suitable for long-term use or large-scale projects.

III. Mobility Methods Based on the mobility method, portable toilets can be classified as lifting and handling types and powered towing types. Lifting and handling toilets rely on lifting equipment for overall lifting, suitable for short-distance relocation or fixed-position installation; powered towing toilets are equipped with a power system or towing device, enabling long-distance movement through vehicle traction, with higher flexibility, often used in emergency rescue or touring service scenarios.

IV. Sewage Treatment Methods Sewage treatment methods are the core technological differences of portable toilets, mainly divided into three types: water-flush and waterless suction types, circulating water-flush types, and dry packing types. Water-flush toilets are flushed with water supplied from a water tank and require regular cleaning of the sewage tank; waterless suction toilets use vacuum suction to collect excreta, saving water and being hygienic; circulating water-flush toilets purify sewage through a filtration system to achieve water resource recycling; dry packing toilets use degradable materials to wrap excreta, requiring no water, suitable for water-scarce areas or scenarios with high environmental protection requirements.

V. Upgraded and Multi-functional Designs To meet diverse needs, portable toilets have also derived upgraded versions, such as a single toilet with a shower room, whose base adopts PVC integrated molding technology, featuring waterproof, moisture-proof, and non-cracking properties, suitable for use in humid environments; the grid-style independent single room achieves unisex use through partition walls and a rain-proof corridor design, serving as both a toilet and a shower room, improving usage frequency and space utilization.
