Requirements for Epidemic Prevention Mobile Toilets

The requirements for epidemic prevention mobile toilets cover three main aspects: structural design, functional configuration, and usage management, as detailed below:

Structural Design

1. Independent Compartments and Enclosed Design
   Epidemic prevention mobile toilets feature independent compartments, with each compartment covering an area of approximately 1.8 square meters (e.g., for epidemic prevention mobile public toilets) or measuring 3m×3m/2m×3m (for container-finished toilet units with a single stall). This ensures individual space for each user, reducing the risk of person-to-person contact.
2. Modular Structure
   The main frame is constructed using lightweight color-coated steel plates or container-based modular steel structures, allowing for rapid addition or removal of toilet stalls. For example, a mobile toilet can be assembled on-site within 3 hours, facilitating emergency deployment and flexible adjustments.
3. Stability and Portability
   Container-finished toilets are primarily built with steel structures, balancing stability and portability. They can be reused and adapted to various scenarios as needed.

Functional Configuration

1. Sanitary Facilities
   Basic equipment includes sinks, hand sanitizer, deodorizers, and trash bins; some are upgraded with automatic hand sanitizer dispensers, disinfectant sprays, and foot-operated flushing mechanisms to avoid hand contamination.
2. Disinfection Facilities
   • Space Disinfection: A nano-mist sterilization system automatically disinfects the interior space with nano-level mist after each use.
   • Pipe Disinfection: Water supply and sewage pipes, along with integrated storage units, are designed with closed disinfection functions to prevent virus transmission through fluids.
   • Antibacterial Materials: The interior walls are coated with photocatalyst plates that automatically decompose harmful substances, inhibit bacterial growth, and eliminate odors.
3. Ventilation System
   Air circulation is achieved through top vents and sidewall exhaust fans, or by using negative pressure fresh air and exhaust systems combined with patented deodorizers and air circulation technology to quickly purify indoor and outdoor air.
4. Sewage Disposal System
   Depending on requirements, fecal storage tanks (with capacities ranging from 0.5m³ to 2m³ and sealed designs to prevent odor leakage) or direct discharge pipes are provided. Some models support customizable volumes to suit different usage scales.

Usage Management

1. Signage and Guidance
   The exterior is marked with an “Epidemic Prevention Only” sign to clarify usage scope; guidance signs are set up to remind users to maintain spacing when using the toilets to avoid crowding.
2. Disinfection and Maintenance
   Dedicated personnel are assigned to disinfect the toilets regularly (at least twice daily), with thorough disinfection of pipes and compartment surfaces after events. Daily maintenance includes emptying fecal storage tanks, checking the operation of ventilation equipment, and replenishing disinfectants.
3. Supply Provision
   Emergency supplies such as toilet paper and disinfectant wipes are provided to ensure users have access to basic sanitary products at all times.
4. Staffing Ratio
   For large events, the principle of “人流密度与设施配比” (user density to facility ratio) is followed, with at least one toilet unit provided for every 500 people to ensure usage efficiency and epidemic prevention safety.
