Portable Sanitary Toilet
A portable sanitary toilet is a facility that can be moved as a whole to provide toilet services for the public and customers, with various types and features.
I. Basic Components A portable sanitary toilet generally consists of a fecal sewage storage tank (or fecal sewage treatment device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and moving device, among others. These components work together to ensure the basic usability and portability of the toilet. For example, the fecal sewage storage tank is used to collect and treat excreta, preventing environmental pollution; the moving device enables the toilet to be easily relocated from one place to another.
II. Classification by Structure and Moving Method According to the structural form, they can be divided into single-structure portable toilets and composite-structure portable toilets. The single structure is relatively simple and suitable for places with limited space or high requirements for moving flexibility; the composite structure is more complex and may have more functions and better stability. According to the moving method, they can be divided into hoisting and handling portable toilets, and powered and towed portable toilets. Hoisting and handling types are suitable for short-distance moving or transfer via lifting equipment; powered and towed types can be moved over long distances by vehicle traction.
III. Classification by Sewage Treatment Method According to the sewage treatment method, they can be divided into water-flush and waterless-flush suction portable toilets, circulating water-flush portable toilets, and dry-packing portable toilets. Water-flush and waterless-flush suction types can promptly clean up excreta to keep the toilet clean; circulating water-flush types can save water resources by reusing water through a circulating treatment system; dry-packing types do not require water and pack excreta for treatment, suitable for water-scarce areas or places with high environmental protection requirements.
IV. Special Types There is also a portable sanitary toilet with a dry-wet separation design that combines the convenience of a portable toilet with the stability of a fixed structure. It can be moved to different places such as railway stations, docks, and tourist attractions. Its interior is usually equipped with a toilet (which can also be replaced with a squat-type toilet), wall-mounted fixtures, a washbasin, an LED lighted mirror, and some are even equipped with shower facilities, with frosted glass doors for dry-wet separation. In addition, some people use water storage tanks to make solar-powered portable toilets, and there are also portable commodes designed for the inconvenience of the elderly and pregnant women at home when using the toilet.
