Qinhuangdao Water-Saving Mobile Toilets
Qinhuangdao's water-saving mobile toilets mainly include two types: vacuum-type eco-friendly toilets and microbial decomposition-type mobile public toilets.
Vacuum-type eco-friendly toilets:
This type of toilet employs vacuum suction technology, rapidly removing waste from the toilet bowl through air pressure differentials while also absorbing odors. Its core advantage lies in its outstanding water-saving performance, requiring only 0.5 to 1 liter of water per flush, compared to the 6 liters needed by traditional water-saving toilets, significantly reducing water consumption. Its working principle involves using a vacuum pump to suction and crush waste before transferring it to a waste tank, while simultaneously removing 30 to 40 liters of air surrounding the waste, effectively preventing odor retention. Additionally, these toilets are clean, tidy, and comfortable, and are easily movable. They are currently widely used in high-end fields such as high-speed trains and airplanes, where hygiene and water conservation requirements are high, demonstrating the integration of technology and practicality.
Microbial decomposition-type mobile public toilets:
These toilets utilize specialized microbial technology, requiring no water flushing and no connection to water supply or drainage systems. They decompose feces using specific microorganisms cultivated by the Chinese Academy of Sciences. The decomposition process converts feces into carbon dioxide (CO₂) and nitrous oxide (N₂O), achieving the crushing and digestion of feces and reducing pollutant emissions at the source. These toilets are intelligently controlled by microcomputers, featuring automated management functions that require no manual intervention. They are also equipped with automatic electronic ventilation fans, voice prompts, and soft music to enhance the user experience. Their application scenarios are extensive, particularly suitable for public places such as squares, tourist attractions, parks, and city streets. They not only address the water consumption issues of traditional public toilets but also adapt to the usage needs of outdoor environments.
Both types of toilets are designed to meet Qinhuangdao's water-saving needs but follow different technological paths: vacuum-type toilets focus on efficient water conservation and odor control, suitable for high-mobility scenarios; microbial decomposition-type toilets emphasize waterlessness and ecological friendliness, suitable for areas without infrastructure support. The promotion and application of these two types of toilets provide diverse solutions for the water-saving transformation of urban public toilets.
