The Principle of Movable Environmental Toilets
The principles of movable environmental toilets vary depending on their types, mainly including mobile environmental public toilets, lifting public toilets, ecological public toilets, and vacuum self-priming toilets.
Mobile environmental public toilets are designed based on new materials and water-saving technologies. Their core principle lies in automatically collecting hand-washing water and adding special agents. During user operation, the hand-washing water is collected and treated for toilet flushing. By adding special agents, the cleaning ability of the water is enhanced, achieving a flushing effect with only 0.46 liters of water per person, significantly saving water resources.
The operation principle of lifting public toilets mimics that of elevator shafts. The toilet box, made of stainless steel, comes with a hydraulic system. These toilets are usually buried 1.5 meters underground, completely disappearing from the ground surface during the day, without affecting urban landscapes and traffic. At 11 p.m., the hydraulic system activates, and the toilet box pops up on time. After rising, the slots automatically lock to ensure safety. At 4 a.m., the toilet box automatically descends, and even the manhole cover fits tightly, restoring the ground to its original flat state.
Ecological public toilets are based on solid-liquid separation technology and achieve harmless treatment of excreta through microbial decomposition. During initial operation, 70 - 80 kilograms of water need to be injected at once to maintain the activity of the microbial community. Subsequently, they feature water-saving, movable, and waterless flushing characteristics. Modern ecological public toilets apply advanced microbial community technology, which can decompose feces into carbon dioxide, water, and organic fertilizer, realizing the recycling of resources. At the same time, they also apply 5G and Internet of Things technologies for remote monitoring, facilitating managers to promptly understand the operation status of the toilets.
Vacuum self-priming toilets are made entirely of 304 stainless steel and have automatic flushing. Their operation principle is the same as that of vacuum toilets on high-speed trains and airplanes. A negative pressure is generated through a vacuum system to quickly suck excreta into storage tanks. If there is an odor in the toilet, a button can be pressed to disperse it, keeping the toilet air fresh. These toilets have the advantages of water-saving, hygiene, and environmental protection, and are suitable for various places.
