Guozheng Mobile Toilet

“Guozheng Mobile Toilet” is not a standard universal term, and no clear corresponding definition has been retrieved so far. However, a general explanation can be provided based on the common concept of “mobile toilet”.

A mobile toilet (Portable toilet) is a public sanitation facility that can be moved as a whole and flexibly deployed, primarily used to meet the toilet needs in fixed or temporary locations. Its core features include portability (position adjustment through lifting, towing, or manual handling), modular design (supporting single or composite structure combinations), and wide adaptability (suitable for densely populated areas such as stations, docks, tourist attractions, and large event venues).

From a structural perspective, mobile toilets are mainly divided into two categories:

• Single-structure mobile toilets: Designed as independent units with a relatively small volume, suitable for scenarios with limited space or temporary needs, such as small event venues or remote areas.
• Composite-structure mobile toilets: Composed of multiple units, they can be expanded into multiple toilet stalls and multi-functional areas (such as accessible toilets and management rooms), commonly used in large events or long-term usage scenarios.

Based on the method of movement, they can be classified as:

• Lifting and handling types: Rely on lifting equipment or manual handling, suitable for areas with complex terrain or no power conditions.
• Powered and towed types: Equipped with power systems or connectable to vehicles for towing, they offer high mobility efficiency and are suitable for long-distance or frequent position adjustment scenarios.

Sewage treatment methods are a key technical classification for mobile toilets:

• Water-flush and non-water-flush suction types: Reduce odors through water flushing or vacuum suction, requiring regular cleaning of the fecal storage tanks, suitable for locations with water sources or sewage disposal facilities.
• Recirculating water-flush types: Utilize biodegradation or chemical treatment technologies to purify sewage, enabling water resource recycling and offering strong environmental protection.
• Dry-pack types: Use biodegradable bags to collect excreta, requiring no water source, suitable for water-scarce or ecologically sensitive areas.

Practical application cases: During the 2025 commemoration of the 80th anniversary of the victory of the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War, Beijing deployed 140 mobile toilets around the Great Hall of the People and the National Museum of China, including tent-type, towed-type, and single-unit types, providing over 3,500 toilet stalls. In 2026, after upgrading the tent-type toilets in the Tiananmen area, stainless steel materials were used, the enclosures were heightened, accessible facilities and intelligent guidance systems were added, significantly improving privacy, safety, and user experience.
