Installation of Mobile Public Toilets in Beijing
The installation of mobile public toilets in Beijing covers multiple aspects, including upgrades and renovations, material and structure, sewage treatment, scheduling and management, and applicable venues.
Upgrade of Tent-style Temporary Public Toilets in the Tiananmen Area
During the peak tourist season from March to November each year, tent-style temporary toilets are set up in the Tiananmen area to provide all-day operational services. In 2026, Beijing Environmental Sanitation Group's Urban Mechanical Sweeping Company carried out a comprehensive upgrade of these toilets. The upgrades included adding barrier-free restrooms for the convenience of disabled individuals; raising the height of the squat stall partitions to 1.8 meters to enhance privacy protection; installing independent partitions to further safeguard users' private space; adding convenience facilities such as handrails, coat hooks, and shelves to improve the user experience; and implementing intelligent vacant stall guidance to help users quickly find available stalls.
Materials and Structure of Mobile Toilets
The structural bodies of mobile toilets are mostly made of high-density polyethylene or fiberglass-reinforced plastic materials. These materials significantly reduce the self-weight while ensuring strength, facilitating easy movement and installation. Their functional modules, including the structural body, water supply and drainage system, sewage treatment system, ventilation system, and electrical system, have all undergone lightweight and standardized renovations, improving the versatility and maintainability of mobile toilets.
Sewage Treatment Methods for Mobile Toilets
Mobile toilets employ various sewage treatment methods, including self-circulating and direct-discharge types. Self-circulating mobile toilets come with their own freshwater and wastewater tanks and operate using microbial degradation or vacuum suction technology, making them suitable for venues without access to municipal sewage networks. Direct-discharge mobile toilets are connected to the municipal sewage network and discharge sewage directly into the urban sewage treatment system.
Installation and Scheduling Management of Mobile Toilets
The scheduling management of mobile toilets is transitioning from manual inspections to digital platforms. Sensors installed in each mobile toilet unit can monitor the liquid level in the tank, battery level, and internal temperature and humidity in real-time. Based on the monitoring data, the system automatically sends cleaning instructions and plans the routes for suction vehicles, improving scheduling efficiency and response speed.
Applicable Venues for Mobile Toilets
Mobile toilets are suitable for stations, docks, tourist attractions, large construction sites, squares, densely populated public places, and bustling commercial streets, among others. They compensate for the insufficient number and unreasonable layout of public toilets, meeting people's restroom needs in various scenarios.
