Qinghai Mobile Ecological Toilet
Qinghai mobile ecological toilets mainly include three types: plateau photovoltaic micro-flush resource-utilization ecological toilets, finished mobile public restrooms, and scenic area mobile toilets.
Plateau Photovoltaic Micro-Flush Resource-Utilization Ecological Toilets: These toilets represent an innovative approach to mobile ecological toilets in Qinghai. On June 30, 2026, the first toilet of this type in the country was put into use in Malayi Village, Maduo County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province, and simultaneously covered Yangjiashan Village in Haidong City. Its core technologies include photovoltaic power generation, micro-flush, graphene heating, and microbial degradation. In Malayi Village, the public restroom is equipped with 22 photovoltaic panels and a 20-kilowatt-hour energy storage battery, utilizing micro-flush technology to achieve a water-saving rate of up to 87%. It is also equipped with a two-eight purification tank for sewage treatment, effectively addressing the challenges of water scarcity and sewage treatment in high-altitude cold regions. In Yangjiashan Village, the public restroom adopts a waterless flush technology, and the household toilets are equipped with photovoltaic heating and lighting systems, achieving 'zero electricity cost' operation and 'zero pollution' degradation and return to the fields, providing new ideas for the construction of ecological toilets in plateau regions.
Finished Mobile Public Restrooms: These toilets are suitable for scenic spots, temporary construction sites, and other locations. They are prefabricated in factories and can be used immediately upon connection to water and electricity on-site. Their design emphasizes practicality and convenience, with separate facilities for men and women, as well as barrier-free compartments for the disabled, meeting the needs of different user groups.
Scenic Area Mobile Toilets: In response to the characteristics of high altitude, low temperature, and fragile ecosystems in Qinghai's scenic areas, mobile toilets in these areas adopt movable and modular designs, making them a practical choice for addressing the challenges of fixed toilet construction. Their frames are typically made of lightweight metals or high-strength composite materials, and their internal facilities focus on water-saving and anti-freezing functions, such as using pressure flushing systems or vacuum technology to reduce failures caused by freezing in high-altitude cold regions. For areas with limited water resources in scenic spots, some mobile toilets are also equipped with biological degradation treatment units, which decompose waste through microorganisms to achieve resource recycling and effectively protect the ecological environment of the scenic spots.
