Mobile Toilet Environmental Protection
Mobile environmental-protection public toilets achieve environmental goals through technological innovation and resource recycling, representing an important development direction for modern public sanitation facilities.
I. Water-Saving and Resource Recycling Technologies
Mobile environmental-protection public toilets employ various technological solutions to reduce water consumption:
- Waterless Flush Type: No need to connect to water supply and drainage pipes; physical or chemical methods are used to treat excreta, suitable for water-scarce areas or temporary scenarios.
- Foam Sealing Type: Foaming liquid is used to cover the surface of excreta, blocking odors and reducing flushing water volume, with significant water-saving effects.
- Water Flush Type: Requires connection to water supply and drainage pipes but achieves water conservation through rainwater collection and filtration systems and handwashing water secondary flushing technology. For example, intelligent water-saving ecological public toilets can collect urine and handwashing water, and after adding special agents, achieve a flushing effect with only 0.46 liters of water per person.
- Recirculating Water Flush Type: Equipped with intermittent aerobic and anaerobic treatment devices, biological strains are added, and biofilm technology is used to accelerate the decomposition of fecal sewage. The treated water can be recycled for flushing, forming a closed-loop system.
- Dry Packaging Type: No water flushing device; excreta is collected by biodegradable plastic bags, which are automatically replaced after use and collected centrally for treatment, avoiding water waste.
II. Intelligence and Efficient Management
Some mobile environmental-protection public toilets integrate intelligent systems to enhance operational efficiency:
- Bottom-level PLC Data Acquisition System: Monitors equipment operation status in real-time.
- 40-inch LED Toilet Cubicle Monitor: Displays toilet cubicle usage status to guide user flow.
- 4G Remote Monitoring Module: Supports remote control of lighting and flushing systems via a mobile app, reducing labor maintenance costs.
III. Material and Structural Design
- Frame: Made of national standard steel welding, with surfaces covered with anti-corrosion and fire-resistant materials such as color-coated steel plates or carved panels, with a service life of over 20 years.
- Internal Systems:
- Independent toilet pit partitioned treatment system: The urine channel utilizes gravity flow, while the feces channel is cleaned by a piston-type scraper mechanical device.
- Equipped with anti-slip floors, automatic flushing toilet bowls, and ventilation and lighting systems, complying with the GBLT18091-92 standard.
IV. Application Scenarios and Policy Support
The product line of mobile environmental-protection public toilets covers细分场景 (sub-scenarios) such as construction site temporary toilets, scenic area garden toilets, and vehicle-mounted toilets, and has been widely applied in public places such as scenic areas, service areas, and rural areas. According to the Regulations on the Management of Public Toilets in Chengdu, when hosting large-scale events, environmental-protection mobile toilets must be set up to meet temporary needs, reflecting their flexibility and necessity.
