Shandong Public Mobile Toilet Design

The design of public mobile toilets in Shandong requires comprehensive consideration of functional zoning, sanitary fixtures, facility provision, spatial environment, water conservation and odor control, site selection, and other special requirements to ensure they meet usage needs and environmental standards.

1. Layout and Functional Zoning
Each functional area should be independently set up, including toilet stalls, urinal stalls, disabled stalls, unisex stalls, and a management room. Separate male and female entrances or privacy screens should be provided at the entrance to ensure privacy. Toilet stalls should be equipped with individual unit spaces, with the distance between the partition panels/doors and the floor controlled between 100-150mm, and the top lower than the ceiling. Heights vary by toilet category: approximately 2.0 meters for Class I, greater than 1.8 meters for Class II, and greater than 1.5 meters for Class III. Independent urinal stalls should have partition panels at a height of 0.8 meters to avoid visual interference.

2. Sanitary Fixtures and Smart Design
Squat toilets should be the primary type, with a certain proportion of sit-down toilets equipped with disposable seat covers to enhance hygiene. Flushing devices should preferably use automatic sensors or foot pedals to reduce contact contamination; non-contact faucets and hand sanitizers should be used, with hands dried using hand dryers or disposable towels after washing. The main door should be designed to open bidirectionally for easy emergency evacuation.

3. Facility Provision and Signage System
Clear signage should be placed within the service area to guide users to their destinations quickly. Basic facilities such as lighting, ventilation, and fly and rodent control devices should be fully equipped, with a focus on reliability, low failure rates, and ease of maintenance when selecting fixtures. Ancillary facilities (such as plumbing and electrical circuits) should be concentrated in separate corridors to avoid interfering with the usable space.

4. Space Optimization and Lighting/Ventilation
The interior space should be reasonably planned to enhance comfort by increasing the lighting coefficient (with artificial lighting added if necessary) and air circulation. Adequate space should be reserved in front of and behind toilet stalls, and the positions of flushing and drainage pipes should be adjusted to avoid usage conflicts. Class I mobile toilets should be equipped with heating (in winter) and air conditioning (in summer) to ensure appropriate temperature and humidity.

5. Water Conservation and Environmental Technologies
Promote the use of 6L/flush water-saving flushing systems. In areas with conditions, biological or chemical treatment technologies can be adopted to achieve sewage recycling, with treated water quality meeting environmental standards. For example, microbial degradation toilets reduce water usage by decomposing feces, while foam-sealed toilets use foam to suppress odors and save water.

6. Odor Control and Ventilation Design
Natural ventilation should be prioritized, with mechanical ventilation added if the air exchange rate is insufficient. Each toilet stall should have an air exchange rate of not less than 40m³/h, and urinal stalls not less than 20m³/h; when relying solely on mechanical ventilation, the air exchange frequency should be more than three times per hour to ensure fresh air.

7. Site Selection and Safety Requirements
Sites should be located at least 30 meters away from food industries, childcare facilities, and centralized water supply points to avoid contamination risks. Class I toilets should have a management room, with toilet stall partitions not lower than 1.8 meters. Septic tanks or fecal storage tanks should be sealed, covered, and leak-proof. Toilets in key tourist areas should meet Class I water-flush standards, with additional facilities such as automatic hand washing, hand dryers, dressing rooms, and aesthetic enhancements.
