Jianhe Mobile Environmental Toilet Customization

Customization of mobile environmental toilets in Jianhe requires consideration of core elements such as technical routes, structural design, material selection, and functional configurations. Below are the key points of the specific plan:

1. Selection of Technical Routes The core of mobile environmental toilets lies in the excreta treatment technology, with two common solutions:

• Biological Treatment Type: This method achieves excreta decomposition through a closed fermentation chamber. Using aerobic bacteria under controlled temperature and humidity conditions, excreta is converted into carbon dioxide, water vapor, and a small amount of solid residue. This technology does not require external water sources or sewage pipe networks, making it suitable for areas without infrastructure. However, regular cleaning of solid residues is necessary.
• Circulating Flush Type: Equipped with a clean water tank and a wastewater tank, this solution uses membrane separation technology to filter flush water, combined with ultraviolet disinfection devices for water recycling. This plan requires regular removal of the wastewater tank, but the user experience is closer to that of traditional water-flush toilets, making it suitable for scenarios with high hygiene requirements.

2. Internal Structure and Functional Design

• Functional Zoning: The toilet body is divided into a functional compartment and an equipment compartment. The functional compartment is equipped with a toilet, a handwashing sink, an exhaust fan, etc.; the equipment compartment houses the water tank, control motherboard, and energy storage battery (supporting use at night or in areas without mains electricity).
• Odor Prevention and Ventilation: A negative pressure ventilation system is adopted, with activated carbon filters installed in the exhaust ducts to purify odors. A louvered air inlet is set at the bottom of the toilet door to create a slightly negative pressure environment, forcibly removing odors.
• Winter Freeze Protection: The pipeline under the handwashing sink is wrapped with an electric tracing belt and covered with rubber-plastic insulation cotton; the thermostat automatically activates the heating circuit when the temperature drops below 5°C to prevent pipe freezing.

3. Appearance and Material Selection

• Toilet Body Material: The main body is made of galvanized steel plate, with a fluorocarbon paint coating on the surface, providing corrosion resistance and UV resistance, suitable for high-temperature and high-humidity environments.
• Bottom Design: The feces collection tray is set with a slope to ensure that solid-liquid mixtures naturally flow to the treatment unit, avoiding residue buildup.
• Modular Structure: Supports rapid disassembly and transportation, allowing adjustment of the number and layout of toilet compartments according to site requirements.

4. Excreta Treatment and Removal

• Biological Treatment Type: Solid residues need to be regularly extracted by professional vehicles and sent to treatment plants for composting or incineration; some models are equipped with automatic packaging devices to simplify the removal process.
• Circulating Flush Type: When the wastewater tank is full, it is transported to the municipal sewage network via a suction truck; the addition of a liquid level sensor allows real-time monitoring of capacity and early warning of removal time to prevent overflow.

5. Customized Extended Functions Depending on needs, intelligent monitoring systems (such as remote monitoring of water level and battery level), energy-saving devices (solar panel power supply), and barrier-free facilities (handrails, low-position handwashing sinks) can be added to enhance usability and management efficiency.
