Quzhou Pollution-Free Mobile Toilets

Quzhou pollution-free mobile toilets mainly include three types: environmentally friendly mobile public toilets, dry-packaged mobile toilets, and mobile public toilets with foam blocks.

Environmentally friendly mobile public toilets: These toilets are equipped with intermittent aerobic and anaerobic treatment equipment specifically designed for treating fecal sewage. During the treatment process, biological strains are added, and biofilm technology is employed. Biofilm technology accelerates the fermentation and decomposition process of sewage, enabling faster breakdown of organic matter in the sewage. After treatment and filtration, the recovered sewage can be used for cleaning toiletries, achieving water resource recycling. Meanwhile, the use of advanced sewage treatment technology for feces not only saves a significant amount of water resources but also substantially reduces the volume of fecal suction sewage, thereby lowering environmental pollution.

Dry-packaged mobile toilets: These toilets have no drainage devices, and their uniqueness lies in the way excreta are collected. Excreta are collected in biodegradable plastic bags placed beneath the sanitary materials. After each use by one person, the system automatically replaces the plastic bag with a new one, ensuring hygiene and convenience. After use, the bags containing excreta only need to be transported to a disposal plant for treatment. This design greatly conserves water resources, facilitates the collection of dirt, avoids problems such as sewage leakage that may occur in traditional toilets, and is environmentally friendly.

Mobile public toilets with foam blocks: They use foam generated from a foam-liquid mixture to replace the water used for toilet flushing. The side walls of the toilet are equipped with foam channels, and compressed air delivers the foam into the toilet bowl, covering the entire surface. After the user finishes, the foam serves a cleaning function, replacing the traditional water-flushing method. Additionally, this system can collect the foamy water near the hand-washing area, further maximizing water resource conservation, reducing water waste, and also lowering the environmental impact of sewage discharge.
