Portable Toilet

A portable toilet is a facility that can be moved as a whole and provides public restroom services, suitable for various locations and featuring multiple classifications and characteristics.

Suitable Locations

Portable toilets are suitable for stations, docks, tourist attractions, villa areas, newly built residential communities, large construction sites, squares, densely populated public places, and bustling commercial streets. These locations often have temporary or periodic demands for toilets, or it is relatively difficult to build permanent public restrooms. Portable toilets can effectively compensate for the shortage in the number of public restrooms and their unreasonable layout. For example, in 2023, mobile toilets were gradually installed and put into use in the scenic area along the Yellow River in Lanzhou, meeting the restroom needs of tourists.

Composition Structure

Generally, they consist of a fecal sewage storage tank (or fecal sewage treatment device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. These components work together to provide users with a complete restroom environment.

Development History and Materials

Initially, mobile toilets were made of materials such as wood, with simple structures and functions, and were prone to absorbing odors. Later, they gradually evolved to use materials like fiberglass and polyethylene, which offer better durability and odor resistance.

Classification Methods

• By structural form: They can be divided into single-structure mobile toilets and composite-structure mobile toilets.
• By mobility method: They can be classified as lifting and handling mobile toilets, and powered and towed mobile toilets.
• By sewage treatment method: They are categorized into water-flush and waterless suction mobile toilets, circulating water-flush mobile toilets, and dry-packing mobile toilets.

Characteristics and Advantages

They can be conveniently transported to any location where restrooms need to be set up and can be used repeatedly. They have the advantages of being movable, combinable, and easy to transport.

Design Principles

The design should follow the principles of being mobile and convenient, economical and durable; environmentally friendly and beneficial to the environment; improving efficiency and promoting humanity. The overall structure should be lightweight, using lightweight and durable materials as much as possible. The structure should be sturdy. When designing, consideration should also be given to controlling the height and width of the toilet, and the mobile device should be fully considered for completeness and rationality.
