Zhejiang Mobile Smart Toilet System

The Zhejiang Mobile Smart Toilet System integrates mobile environmentally friendly public toilets and smart public toilet technologies, featuring environmental protection and intelligent management, suitable for various public places.

Features of Mobile Environmentally Friendly Public Toilets

The mobile environmentally friendly public toilets in Zhejiang do not rely on underground sewage networks. They adopt a modular structure, enabling quick installation, disassembly, and relocation, making them suitable for temporary events, construction sites, tourist attractions, transportation hubs, and other locations. Their technical features are as follows:

• Waterless or Water-Saving Technologies: Some adopt waterless flushing systems, such as wrapping waste with biodegradable films or using vacuum suction technology; others are equipped with micro-water flushing devices, consuming far less water than traditional water-flushing toilets.
• Waste Treatment and Resource Utilization: Microbial agents are used to decompose excreta into harmless organic substances or fertilizers; safe chemical agents are employed for disinfection and decomposition; liquids and solids are separated, with the solid portion treated through composting and the liquid portion filtered and purified for discharge that meets standards or used for non-potable purposes, such as greening irrigation; waste is automatically sealed and packaged for easy centralized treatment, preventing odors and pollution.
• Energy Supply: They are often equipped with solar photovoltaic panels, utilizing solar energy to power lighting, ventilation, and control systems, reducing reliance on the power grid.
• Materials and Structure: The main structures mostly use lightweight, sturdy, and corrosion-resistant composite materials, facilitating easy cleaning and maintenance; the design emphasizes ventilation and deodorization to ensure fresh indoor air.

Features of Smart Public Toilets

Taking Edi (Hangzhou) Environmental Technology Co., Ltd. as an example, smart public toilets achieve intelligent management through an automatic closed loop of 'perception—analysis—decision-making—execution'.

• Perception Layer: Multiple sensors are deployed. Millimeter-wave human body radars accurately determine toilet stall occupancy status; multi-in-one gas sensors continuously monitor ammonia, hydrogen sulfide, PM2.5, and temperature and humidity; wireless laser ranging sensors continuously detect the remaining amounts of hand sanitizer and toilet paper and the overflow status of trash bins, with a battery life of up to three years and IP67-level protection, enabling stable operation in humid bathroom environments and dusty industrial scenarios.
• Transmission Layer: Although not elaborated in detail in the text, it can be inferred that this layer is responsible for transmitting data from the perception layer to the cloud. The system can obtain real-time data on toilet stall occupancy status, air quality, and hand sanitizer levels, and after transmitting this data to the cloud, it automatically determines whether to dispatch cleaning staff, activate fresh air systems, or send reminders for restocking.
