Research and Production of Mobile Toilets

The research and production of mobile toilets involve various technological types and several representative enterprises, with the core focusing on environmental protection, convenience, and scenario adaptability.

I. Technological Types and Characteristics

1. Water-saving and Environmentally Friendly Technologies

   • Micro-flush Toilet Technology: Utilizes intelligent sensors to distinguish between solid and liquid waste, employing different flush volumes accordingly, averaging only 0.75L per person per use, significantly reducing water consumption.
   • Foam Sealing Technology: Uses a foam layer to isolate odors, replacing traditional water seals, with water consumption not exceeding 30ml per person per use, suitable for water-scarce or temporary scenarios.
   • Vacuum Collection Technology: Relies on vacuum negative pressure to suction waste, achieving low water volume (approximately 0.5L per use), odor-free operation, and waste volume reduction, commonly used in high-end events or special environments.

2. Waterless Treatment Technologies

   • Packaging Toilets: Adopts biodegradable film to package waste, supporting foot-pedal or electric packaging, requiring no water flushing, suitable for areas without plumbing, such as wilderness or disaster zones.

3. Modular Installation Technologies

   • Some enterprises (e.g., Junhan) employ prefabricated modular designs, with toilet bodies manufactured in factories and quickly assembled on-site by connecting columns and fixing structures, eliminating the need for civil engineering and shortening deployment cycles.

II. Representative Enterprises and Products

1. Shanghai Huajie Ecological Environment Engineering Co., Ltd.

   • Develops solar-powered and rainwater-collecting mobile toilets, integrating renewable energy with water-saving designs, serving extreme environments such as the Shanghai World Financial Center and the Olympic torch relay on Mount Everest, as well as covering large-scale events like marathons.

2. Beijing Zhongjiehui Sanitation Equipment Co., Ltd.

   • Offers a diverse product line including antique-style and landscape-style mobile toilets, meeting aesthetic and functional needs in tourist attractions and urban public spaces.

3. Beijing Aibei Space Technology Co., Ltd.

   • Relying on teams from Tsinghua University and other institutions, develops core technologies such as micro-flush and foam sealing, and undertakes the operation and maintenance of mobile toilets for national-level events like the Beijing Olympics and National Day celebrations, demonstrating high technical maturity and scenario adaptability.

III. Application Scenarios and Advantages The research and production of mobile toilets closely align with practical needs:

• Special Environments: Such as high altitudes (Mount Everest) and high-rise buildings (Shanghai World Financial Center) requiring solutions for water supply and waste disposal.
• Large-scale Events: Marathons, military parades, and other short-term, high-traffic scenarios requiring rapid deployment and efficient operation and maintenance.
• Resource-Scarce Areas: Arid regions or temporary disaster zones relying on waterless or water-saving technologies to ensure basic sanitation needs.

Their core advantages lie in flexibility (movable, modular), environmental friendliness (water-saving, pollution-free treatment), and adaptability (covering extreme environments to daily scenarios), making them important facilities for modern urban management and emergency response.
