Ezhou Rural Mobile Toilet Design

The design of mobile toilets in rural areas of Ezhou should focus on modularity, environmental adaptability, and resource utilization, achieving flexible deployment and sustainable operation through integrated sewage systems, scenario-based configurations, and long-term maintenance mechanisms.

Sewage and Cleaning Systems

Mobile toilets adopt an integrated design independent of urban sewage networks. Taking foam-sealing toilets as an example, a micro foam generator creates a foam layer in the toilet bowl to cover excreta, with a flush volume of only 1%-2% of traditional toilets, effectively isolating odors and reducing water consumption. Excreta is temporarily stored in sealed collection tanks and regularly transported by leasing agencies to designated treatment stations using suction trucks. Some agencies employ a "solid-liquid separation + anaerobic fermentation" pretreatment technology, where solids are converted into organic fertilizer base materials, and liquids are purified and incorporated into municipal sewage networks, achieving resource recycling.

Environmental Adaptability Design

Targeted optimizations are required based on Ezhou's climate and terrain characteristics:

• Temperature Regulation: Low winter temperatures (average January temperatures of 4°C-8°C) may reduce foam viscosity, necessitating adjustments to foam solution formulations or the addition of heating devices.
• Site Adaptation: Hardened surfaces allow direct placement; muddy ground requires steel plates or concrete bases to prevent tipping; narrow mountain roads utilize disassemblable structures for easy transportation.
• Moisture and Slip Resistance: During the plum rain season with high humidity, the interior floor adopts anti-slip grid designs, and sealing strips are regularly inspected to prevent moisture infiltration.

Capacity and Configuration Optimization

Configurations are dynamically adjusted based on usage scenarios:

• Single-Unit Service Capacity: A standard mobile toilet unit can serve 80-150 people every 8-12 hours; exceeding this threshold requires increasing the number of units or shortening cleaning cycles.
• Scenario-Based Configurations: Large events are deployed according to peak demand, while construction sites determine quantities based on the number of workers and duration (e.g., 2 units for 100 people, 5-8 units for over 1,000 people).
• Customization for Special Needs: Pet exhibitions add anti-slip mats and pet pathways; high-traffic scenarios like concerts are equipped with hand sanitizers and air fresheners.

Structural and Material Selection

• Shell Material: High-density polyethylene or fiberglass is commonly used, resistant to corrosion and lightweight (empty weight of 150-250 kg), facilitating loading and unloading.
• Fixing Methods: Anchor bolts or weighted water bags (suitable for temporary sites) ensure stability.
• Ventilation System: Roof exhaust fans or natural vents combined with activated carbon filters control odor diffusion.

Maintenance and Environmental Protection Measures

• Cleaning Cycles: Chemical solutions are replenished or sewage tanks are cleaned every 3-5 days in summer; pipes are wrapped with insulation materials or antifreeze is added in winter.
• Excreta Treatment: Transported by qualified vehicles to sewage treatment plants or fecal sludge treatment stations, with strict prohibition of direct discharge to prevent environmental pollution.
• Long-Term Management: Drawing on the management experience of rural public toilets in Ezhou, full-time or part-time cleaners are assigned to ensure daily cleaning and disinfection.
