Working Principle of New-Type Mobile Toilets
The working principles of new-type mobile toilets vary depending on their types, mainly including traditional sewage-storage types, water-saving or waterless types, solar-powered mobile toilets, and lifting types, among others.
Traditional sewage-storage mobile toilets are equipped with detachable sewage storage tanks inside. When in use, waste directly falls into the tank. To reduce odors and bacterial growth, degradation agents or deodorizers are sometimes pre-placed in the tank. Meanwhile, ventilation systems, such as natural airflow or small fans, are used to maintain air circulation inside the toilet, ensuring a relatively comfortable usage environment.
Water-saving or waterless mobile toilets incorporate various technologies. Packaging technology uses mechanical devices to seal waste in biodegradable plastic bags, which are then collected and disposed of uniformly, avoiding water waste. Biodegradation technology utilizes microbial strains to decompose waste into water and carbon dioxide under specific conditions, partially achieving waste reduction and harmlessness, with minimal environmental impact. Circulating filtration and chemical treatment technology purifies the liquid portion for flushing reuse, while the solid portion is separated and stored, improving water resource utilization. Additionally, there are mobile eco-friendly public toilets that automatically collect hand-washing water and add special agents, achieving a flushing effect with only 0.46 liters of water per person, significantly saving water resources.
Solar-powered mobile toilets are equipped with solar panels on the top, using solar energy to drive ventilation systems or lighting equipment. This design is not only environmentally friendly and energy-saving but also enhances the comfort and hygiene level of the toilet, especially in outdoor or remote areas where solar energy becomes a reliable energy source.
Lifting-type mobile toilets, such as the lifting public toilets in the Netherlands, feature stainless steel toilet cabins with built-in hydraulic systems, operating similarly to elevator shafts. They rise at night for use and automatically descend in the morning, with the slots locking automatically when raised to ensure safety. This design saves space and improves the flexibility and practicality of the toilet.
