Purchase of Mobile Toilets for Parks

When purchasing mobile toilets for parks, it is essential to comprehensively consider factors such as structural composition, sewage treatment methods, configuration options, and price.

I. Structural Composition
The main body of a mobile toilet consists of a frame, walls, roof, and functional modules. The frame is typically welded from national standard steel to ensure structural stability; the surface is covered with anti-corrosion and fire-resistant materials such as color-coated steel plates or carved panels, extending the service life to over 20 years. The choice of wall materials is flexible, allowing for the selection of color-coated steel plates, metal carved panels, anti-corrosion wood, stainless steel plates, or aluminum-plastic panels based on the park's environmental needs, balancing aesthetics and durability. The roof must be waterproof and can integrate energy-saving devices such as solar panels. Internal functional modules include fecal sewage storage tanks (or treatment devices), flooring, sanitary fixtures (such as toilets and urinals), washing facilities (sinks and water-saving faucets), water tanks, and mobility devices (wheels or lifting structures) to ensure basic usage requirements.

II. Sewage Treatment Methods
Different treatment types can be selected based on the park's water availability and environmental protection requirements:

1. Circulating Water Flush Type: Equipped with intermittent aerobic and anaerobic treatment devices, this type accelerates fecal decomposition by adding biological strains and biofilm technology. The treated water can be recycled for flushing, suitable for scenarios with limited water resources or the need to reduce sewage discharge costs.
2. Dry Packing Type: Without water flushing devices, excreta is collected in biodegradable plastic bags, which are automatically replaced and collected for centralized treatment after use, avoiding sewage discharge and suitable for ecologically sensitive areas or temporary event venues.
3. Water Flush and Dry Flush Suction Type: Combining water flushing for cleaning and suction for sewage discharge, this type requires regular cleaning of storage tanks and is suitable for areas with convenient water access and the need to maintain high hygiene standards.

III. Configuration Options
Standard configurations include toilets, urinals, coat hooks, vanity mirrors, waste bins, lighting, exhaust fans, door locks, and occupancy indicators to meet basic usage needs. Optional configurations can be upgraded based on the park's positioning:

• Comfort: Climate control systems (heating and cooling), freeze protection systems, and heating systems to adapt to extreme climates; background music to enhance the user experience.
• Environmental Protection: Air purifiers to reduce odors; water-saving faucets to reduce water consumption.
• Functionality: Sinks and vanity mirrors to meet cleaning needs; large mobile toilets can be equipped with showers or母婴室 (nursing rooms).

IV. Price Reference
Prices vary significantly depending on type, configuration, and scale:

• Custom color-coated steel plate mobile toilets (outdoor type) cost approximately 300 yuan per month, suitable for short-term rentals or temporary use.
• Scenic area finely decorated environmental protection public toilets (11 square meters) cost approximately 99 yuan per square meter, offering high cost-effectiveness and suitable for small to medium-sized parks.
• High-end smart types (including showers and intelligent systems) cost approximately 475 yuan each, suitable for high-traffic scenic areas or commercial parks.
• Large integrated public toilets (including multiple toilet stalls and complete facilities) cost approximately 3000 yuan each, suitable for long-term fixed use in large parks.

It is recommended to comprehensively evaluate and select an appropriate model based on the park's foot traffic, budget, and environmental protection requirements, prioritizing designs that can be modularly expanded to accommodate future needs changes.
