Small-Size Simple Portable Toilet

A small-size simple portable toilet is a sanitary facility that can be moved as a whole and is suitable for fixed or temporary locations. It features compact space, integrated functions, and easy transportation.

I. Basic Composition and Functions
A small-size simple portable toilet typically consists of modules such as a fecal sewage storage tank (or disposal device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. Its core function is to meet basic toilet needs, and some high-end models also integrate facilities such as hand-washing basins, lighting, and ventilation. For example, a 5-meter-wide and 2-meter-high intelligent portable toilet has a complete internal configuration and can be put into use directly after factory prefabrication, achieving "buy and use immediately".

II. Structural Classification and Characteristics

1. By structural form: It can be divided into single-unit and modular types. The single-unit type is an independent unit suitable for small-scale use; the modular type can be expanded through module assembly to adapt to different numbers of users.
2. By mobility method: It includes trailer-mounted, self-propelled, and building-block assembly types. The trailer-mounted type relies on vehicle traction; the self-propelled type is equipped with a power system; the building-block assembly type uses lightweight materials and achieves rapid assembly through assembly, with a strong sense of technology and high flexibility.
3. By sewage treatment method: It is divided into direct-discharge, circulating, and packaged types. The direct-discharge type needs to be connected to the municipal sewage network; the circulating type achieves sewage purification through biological degradation or chemical treatment; the packaged type seals and stores feces for regular removal, suitable for scenarios without drainage conditions.

III. Core Advantages

1. Portability: The overall design facilitates lifting or towing, enabling rapid deployment in temporary events, disaster relief, or remote areas.
2. Space efficiency: Through compact layout, the internal space is optimized. For example, an ultra-mini portable toilet integrates necessary functions within limited dimensions, balancing practicality and aesthetics.
3. Environmental adaptability: The circulating and packaged treatment methods reduce dependence on the environment, in line with the concept of green buildings.

IV. Application Scenarios
It is suitable for tourist attractions, construction sites, large gatherings, emergency rescue, and other scenarios. Its modular design also supports functional expansion, such as adding barrier-free facilities or母婴室 (nursing rooms), to meet diverse needs.
