Mobile Toilet at Shenzhen Buji Station
Shenzhen Buji Station (Shenzhen East Station) is equipped with an intelligent and eco-friendly mobile toilet, the first of its kind to be put into use in the city.

I. Basic Structure and Functional Zoning
The mobile toilet consists of four independent compartments, including three unisex compartments (with two seated toilets and one squat toilet) and one maternity and child room. Each compartment covers an area of approximately 1.5 square meters and is equipped with standardized facilities, including toilets, sinks, hand dryers, air conditioners, and other basic amenities. Additionally, it features user-friendly installations such as storage shelves, coat hooks, emergency call buttons, and mirrors, ensuring both practicality and safety. The maternity and child room is separately set up to provide privacy for special groups.
II. Intelligent Management System
The toilet incorporates multiple intelligent functions:
- Automatic Door Opening/Closing and Voice Reminders: Sensors enable automatic closing when unoccupied and opening when occupied, along with a voice announcement system to provide guidance on toilet etiquette and safety information.
- Time Limit for Toilet Use: Each user is limited to a maximum of 15 minutes. As the time limit approaches, voice reminders will be issued, and a progress bar on the exterior door displays the remaining waiting time to prevent prolonged occupation.
- Remote Monitoring and Maintenance: The system can monitor the usage status of compartments, equipment operation, and environmental data in real time, facilitating timely scheduling of cleaning or maintenance by management personnel.
III. Eco-Friendly Technologies and Sustainability
- Water-Free Plumbing Design: Utilizing proprietary technology, the toilet operates without connection to municipal water and sewage systems. It treats wastewater through a reclaimed water circulation system, achieving a water-saving rate of over 70%. An air hand-washing device further reduces water consumption.
- Fecal Resource Utilization: The feces collected in the collection tank can be directly converted into organic fertilizer after dehydration treatment, enabling waste recycling.
- Air Purification: Equipped with a self-developed deodorization device, the toilet maintains fresh indoor air through physical adsorption and biodegradation technologies, minimizing odor diffusion.
IV. Rapid Deployment and Scene Adaptability
The toilet adopts a modular design, allowing for assembly within 15 minutes after being transported to the site by vehicle. It is suitable for various indoor and outdoor settings, including bus stops, municipal parks, exhibition centers, and subway platforms. Its mobility enables flexible responses to temporary events or peak passenger flows while avoiding the long construction periods and site selection constraints associated with traditional public toilets.
Through technological innovation and user-centered design, this facility provides an efficient, eco-friendly, and comfortable toilet solution for public areas, reflecting the trend of intelligent upgrades in urban public service facilities.
