Dongcheng Foam-Sealing Mobile Toilet
There is no direct public information on the 'Dongcheng Foam-Sealing Mobile Toilet', but the technical principles, functional features, and application scenarios of foam-sealing mobile toilets are as follows:
Technical Principles and Water-Saving Performance
Foam-sealing mobile toilets use a foaming device to mix water with a specialized foaming agent in a specific ratio, generating a large amount of fine foam that covers the drainage outlet, forming a physical barrier. Its core technologies include the U-shaped pipe liquid level balancing system and the patented water-free foaming system, which require only 0.04 liters of water per use, achieving a water-saving rate of over 98%. The lubricity of the foam reduces friction between the waste and the inner walls of the toilet, ensuring smooth sliding into the collection tank and preventing blockages.
Odor Control Mechanism and Environmental Protection
This technology achieves efficient odor control through three mechanisms:
- Physical Sealing: A 5-centimeter-thick foam layer directly covers the drainage outlet, blocking the spread of odors;
- Secondary Sealing: A weighted baffle automatically closes after waste passes through, forming a double barrier;
- Biological Decomposition: Microbial communities decompose organic matter in the waste collection tank, further reducing the concentration of harmful gases such as ammonia. Measured data shows that ammonia levels can be reduced to below 0.1 ppm, significantly lower than traditional toilets.
System Composition and Functional Modules
The system consists of four core modules:
- Foaming Device: Includes a liquid storage container, mixing mechanism, airflow generator, and delivery pipeline, responsible for the generation and stable supply of foam;
- Toilet Bowl: Made of special materials and designed to ensure uniform foam coverage and easy cleaning;
- Control System: Monitors parameters such as liquid level and foam thickness through sensors, automatically adjusting the foaming volume and water usage;
- Waste Collection Facility: A sealed collection tank with anti-leakage design, supporting regular removal or biological degradation treatment.
Application Scenarios and Cost-Effectiveness
This technology has been widely applied in urban streets, tourist attractions, construction sites, and polar research stations. For example, public toilets on the Shanghai Bund, stations along the Qinghai-Tibet Railway, and Antarctic research stations all use this technology. Renovation projects in Beijing have demonstrated an 80% reduction in waste removal frequency and a 60% savings in overall operating costs. In terms of pricing, foam-sealing mobile toilets in the Beijing market range from 5,605 yuan to 12,000 yuan, depending on configuration (such as whether equipped with solar power or intelligent monitoring systems) and functional requirements.
Applicability Summary
With advantages such as water conservation, odor control, and easy maintenance, foam-sealing mobile toilets are an ideal choice for scenarios with high foot traffic or water scarcity. For more specific product information in the 'Dongcheng' area, it is recommended to contact local environmental protection equipment suppliers or consult public data on government procurement platforms.
