Tongzhou Mobile Environmental Toilet

Tongzhou mobile environmental toilet is a new choice for eco-friendly and convenient urban public services, featuring mobility, environmental protection, and convenience.

Physical Composition and Mobility

The Tongzhou mobile environmental toilet is fully mobile, relying on a modular box structure. The box is manufactured in a factory with pre-installed internal piping and can be quickly put into operation upon arrival at the site by connecting to a simple base and external interfaces. The internal functional configurations are modular, allowing for the selection of single functional units or combinations of multiple functional units based on actual site conditions and expected foot traffic. This design enables it to flexibly adapt to different urban environments and needs.

Significant Environmental Characteristics

In terms of material selection, the box often uses corrosion-resistant, recyclable metal sheets or composite materials, reducing maintenance frequency and lowering resource consumption throughout its lifecycle. There are multiple technological routes for water resource and waste treatment. In addition to traditional municipal sewer direct discharge, water-saving flushing equipment is a basic configuration. Some units also integrate in-situ treatment technologies such as biodegradation, chemical treatment, or physical filtration, reducing reliance on municipal sewers and making them suitable for temporary sites without sewer coverage. For example, Beijing Aibei Space Technology Co., Ltd. has independently developed a micro-water flushing technology that achieves intelligent flushing, ventilation, and lighting, using different amounts of water for urine and feces, with an average flushing volume of approximately 0.75L per person per use. The pilot "smart micro-water flushing" water-saving public toilet in Beijing's sub-center has achieved a water-saving rate of over 90%. The water flow is mixed with efficient bacteria to decompose odors at the source and effectively prevent freezing in winter. The flushing mode uses a "wrap-around" flushing design, providing wider flushing coverage. The toilet fixtures inside the stalls are made of ultra-high-density ceramics, requiring only a minimal amount of water to flush clean and effectively preventing pipe blockages.

Outstanding Convenience

For management, its rapid deployment and removal characteristics enable public services to keep pace with the rhythm of short-term urban activities. For users, convenience is reflected in accessibility and experience. Through data analysis and demand surveys, toilet locations can be flexibly arranged to more precisely cover high-demand areas. The internal design focuses on efficient space utilization and humanized details, such as forced ventilation systems, lighting, and emergency call devices, ensuring basic hygiene and safety comfort.
