Zhejiang Water-Saving Mobile Toilets
Zhejiang water-saving mobile toilets mainly include types such as vacuum negative pressure mobile toilets, waterless packing toilets, and mobile toilets using biofilm technology, each with unique water-saving principles and applicable scenarios.
The vacuum negative pressure mobile toilet is a typical representative of Zhejiang water-saving mobile toilets. It uses either a soda-water flushing device or a vacuum negative pressure device for water conservation. In the soda-water flushing device, a small amount of water is mixed with compressed air to form a high-impact soda-water mixture for flushing the toilet, significantly reducing water usage compared to traditional water flushing methods. The vacuum negative pressure device, on the other hand, utilizes the negative pressure generated by a vacuum to quickly suck away excreta, requiring only a minimal amount of water to clean the toilet surface. This flushing method greatly reduces water consumption and is suitable for places with high water-saving requirements and a certain power supply, such as large event venues and tourist attractions.
Waterless packing toilets are suitable for places without sewage pipes or septic tanks. They collect excreta using biodegradable plastic bags and do not require water for flushing. After a user defecates, the excreta directly falls into specially made biodegradable plastic bags. When the bags are full, they are replaced and disposed of collectively. This type of toilet completely eliminates dependence on water resources and has significant advantages in remote areas with scarce water resources or places without access to sewage systems, as well as temporary construction sites. It not only solves people's toilet needs but also avoids water waste.
Some Zhejiang water-saving mobile toilets also use biofilm technology to accelerate the fermentation and decomposition of sewage, achieving water resource recycling. Biofilm technology involves setting up biofilm carriers in the sewage treatment system of mobile toilets, where microorganisms attach to the carrier surface to form a biofilm. When sewage flows through the biofilm, microorganisms decompose organic matter in the sewage, converting it into harmless substances. At the same time, the water produced can be further treated and reused for toilet flushing and other purposes, thus achieving the goal of water resource recycling, improving water resource utilization efficiency, and reducing the demand for external water resources.
