Movable Iron Public Toilet

Movable public toilets are facilities that can be moved as a whole and provide toilet services to the public, featuring flexible deployment and reusability.

I. Basic Composition
Movable public toilets consist of multiple functional modules: fecal sewage storage tanks (or disposal units) for collecting or treating excreta; floor slabs, walls, and roofs forming enclosed spaces; sanitary fixtures (such as toilets and squat pans) and washing facilities (such as sinks) meeting basic usage needs; water tanks providing flushing water; and mobile devices (such as wheels and lifting structures) supporting overall transportation. Some high-end models are also equipped with ventilation systems, lighting equipment, or intelligent monitoring modules.

II. Classification Methods

1. By structural form: They are divided into single-unit structures (independent units) and composite structures (combinations of multiple modules), with the latter allowing for the expansion of toilet cubicle numbers through assembly.
2. By mobility method: Lifting and handling types rely on lifting equipment; powered types come with their own driving devices (such as electric wheels); and towed types can be connected to vehicles for towing.
3. By sewage treatment method: Water-flush types require connection to a water source and discharge through pipelines; waterless suction types use vacuum pumps to remove waste; recirculating water-flush types reuse water through filtration systems; and dry-pack types seal feces in replaceable containers, requiring no water source and producing no pollution.

III. Core Advantages

1. Flexible deployment: Not restricted by fixed buildings, they can be quickly deployed or withdrawn according to pedestrian density (such as in business districts or exhibitions) or event needs (such as outdoor music festivals).
2. Reusability: Modular design facilitates the repair and replacement of components, extending the overall service life and reducing long-term costs.
3. Strong adaptability: They can be used in areas without municipal pipe networks, such as remote scenic spots and post-disaster temporary settlement points, with some models even featuring special functions like cold resistance and wind resistance.

IV. Special Form: Tidal Toilets
To address the issue of long queues for female toilets, tidal toilets feature 'gender-neutral universal toilet cubicles' equipped with movable signs or lockable sliding doors, dynamically adjusting the ratio of male to female toilet cubicles based on real-time pedestrian flow. For example, during peak female usage periods, some universal cubicles can be temporarily designated as female-only to balance supply and demand.
