Taiyuan Water-Saving Mobile Toilet
The water-saving mobile toilets in Taiyuan mainly adopt foam sealing technology, achieving efficient water conservation through intelligent water-saving sanitary ware, while also featuring odor blocking and water pressure/flow control functions.
Water-Saving Principle of Foam Sealing Technology
The core of foam-sealed mobile public toilets is intelligent foam water-saving sanitary ware, which generates a dense foam layer inside the sanitary ware through a foam generator. This foam layer completely isolates the interior of the sanitary ware from the external environment, forming a physical sealing barrier that effectively locks in the odors from urine and feces, preventing the overflow of odors from the pipes. Traditional water-flushing sanitary ware requires frequent flushing to remove waste and suppress odors, whereas foam sealing technology reduces the adhesion of waste to the inner walls of the sanitary ware through the lubricating and wrapping effects of the foam, thereby significantly reducing the need for flushing. In actual use, this technology can reduce the number of flushes and the volume of water per flush, achieving a water conservation rate of over 70% compared to traditional methods, significantly reducing water consumption.
Water-Saving Design of the Sanitary Treatment System
The sanitary treatment system of mobile toilets includes a flushing unit, whose water-saving function is achieved through two aspects:
- Water Pressure Control Mechanism: The system dynamically adjusts the water pressure according to the usage scenario to avoid water waste caused by high-pressure flushing. For example, it automatically reduces the water pressure when the amount of waste is small, requiring only a small amount of water to complete cleaning; when the amount of waste is large, it briefly increases the water pressure to ensure effective flushing.
- Flow Rate Control Mechanism: Through the cooperation of a flow sensor and a solenoid valve, the volume of water per flush is precisely controlled. The system can preset different flow parameters according to the type of sanitary ware (such as urinals or toilet bowls), avoiding excessive water usage caused by a one-size-fits-all flushing approach.
Technological Advantages and Application Scenarios
The water-saving effect of foam-sealed mobile toilets is remarkable, and they are both environmentally friendly and practical:
- Environmental Friendliness: They reduce sewage discharge, alleviate the pressure on sewage treatment, and align with the concept of green urban development.
- Adaptability: They are suitable for public places in Taiyuan such as parks, scenic spots, and streets, especially in areas with water scarcity or inconvenient water supply, where their advantages are particularly evident.
- Maintenance Costs: Due to the reduced frequency of flushing, the wear and tear on sanitary ware are minimized, extending the service life of the equipment. At the same time, the frequency and cost of cleaning and maintenance are also reduced.
By promoting such water-saving mobile toilets, Taiyuan has not only enhanced the environmental protection level of public facilities but also provided a replicable technological solution for urban water conservation management.
