Mobile Small Toilet (Outdoor)

A mobile small toilet (outdoor) is a facility that can be moved as a whole and provides public toilet services. It is suitable for places such as stations, docks, and tourist attractions, and has the advantages of being movable, combinable, and easy to transport.

I. Basic Composition
A mobile small toilet typically consists of a fecal sewage storage tank (or disposal device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. Among them, the fecal sewage storage tank is used to collect excreta. Some models are equipped with waterless flushing suction or dry-packing devices to reduce water dependence. The walls are mostly made of materials such as metal carved panels, which have both thermal insulation and heat insulation functions. The mobile device is divided into lifting, towing, or power-driven types according to the design, facilitating transportation and deployment.

II. Classification Methods

1. By structural form: It is divided into single-unit structures (independent units) and composite structures (multi-unit combinations). The latter can be expanded into multiple squatting positions or separate male and female toilet designs.
2. By mobility method: It includes lifting and handling types (requiring lifting equipment), power-towing types (connectable to vehicle traction), etc., to adapt to different terrains and transportation conditions.
3. By sewage treatment method:
   • Water-flushing type: Requires connection to a water source and flushes through a water tank, suitable for places with water supply conditions;
   • Waterless flushing suction type: Uses vacuum or negative pressure technology to collect excreta for regular pumping and treatment;
   • Recirculating water-flushing type: Recirculates water resources through filtration and disinfection systems to reduce emissions;
   • Dry-packing type: Uses biodegradable bags to pack excreta without flushing, suitable for water-scarce or environmentally demanding areas.

III. Application Scenarios and Advantages
Mobile small toilets can be quickly deployed in temporary events, disaster relief, or densely populated areas to solve the problem of insufficient fixed toilets. Their core advantages lie in:

• Flexibility: They can be moved to the required location at any time, avoiding resource waste;
• Economy: Taking the four-squatting-position model produced by Dezhou Hongtu Metal Products Co., Ltd. as an example, the cost is less than 20,000 yuan, which is lower than that of traditional buildings;
• Environmental protection: Dry-packing or recirculating water-flushing technologies reduce sewage emissions, meeting sustainable development requirements.

IV. Typical Case
A four-squatting-position mobile toilet produced by a certain enterprise has dimensions of 4 meters in length and 2.3 meters in width. It adopts a pointed roof design with metal carved panels as the exterior walls. Inside, it is equipped with male squatting positions, urinals, and column basins, balancing practicality and aesthetics, and is suitable for scenarios such as commercial streets or scenic spots.
