Tianjin Wuqing Environmental Protection Mobile Toilet

The Tianjin Wuqing environmental protection mobile toilet is a mobile sanitation facility that treats excreta using physical, chemical, or biological methods. Its core technologies are 'closed-loop' or 'rapid degradation', making it suitable for short-term scenarios.

Technical Principles and Types

The environmental protection mobile toilets used in Wuqing District, Tianjin, mainly fall into two categories:

1. Closed-loop Type: Equipped with a sewage storage tank and a specialized decomposition solution inside. After excreta falls into the tank, the decomposition solution inhibits odors through microbial action or chemical reactions and initially degrades solid matter. This type of toilet does not require connection to a sewer system, making it suitable for short-term scenarios where water and electricity access is inconvenient, such as outdoor events and temporary construction sites.
2. Water Recycling Type: Built with a small-scale sewage treatment system, urine and flushing water are filtered, precipitated, and disinfected before being recycled for the next flush, resulting in extremely low water consumption. A single water charge can support extended use, but it requires an independent generator or solar power supply system to maintain the operation of the water pump and filtration unit, making it suitable for scenarios with high water requirements.

Rental Services and Maintenance

Rental companies (such as Haoshitong Pipeline Engineering and Anjieshi Environmental Protection Engineering) provide full-service processes:

• Preliminary Survey: Assess ground flatness, vehicle accessibility, and sewage discharge paths to ensure the safe deployment of equipment.
• Mid-term Deployment: Configure the number of restrooms based on the estimated number of users and reserve cleaning and maintenance access to avoid disrupting event operations.
• Post-deployment Maintenance: Conduct regular inspections, replace decomposition solutions, replenish cleaning agents, and discharge sewage storage tanks. The frequency of sewage tank discharge needs to be dynamically adjusted, with discharge required after every 50 to 80 uses; otherwise, overflow or odor leakage may occur.

Site Selection and Usage Considerations

• Site Selection Principles: Equipment should be placed downwind of the event area to prevent odor diffusion; at the same time, drainage direction should be considered to prevent sewage backflow.
• Cost Composition: Rental costs include basic rental fees, transportation fees, maintenance fees, and cleaning consumable fees. In municipal engineering projects in Wuqing District, the daily rental fee for a single unit is approximately 200 to 400 yuan, depending on the equipment type and rental duration. Additional accessories (such as anti-slip mats and hand sanitizer holders) can enhance the user experience but are not essential.
