Lhasa Mobile Tourism Toilet
Lhasa mobile tourism toilets mainly include two types: outdoor finished mobile public toilets and ecological toilet mobile public toilets for scenic spots.
Outdoor finished mobile public toilets combine standardization and customization. Their product price is 1200 yuan per unit, with a delivery period of 5 days and a total supply of 780 units. They support customization of materials, specifications, models, and colors according to needs, and the external dimensions are made according to the drawings. In terms of configuration, they include basic facilities such as squat toilets, hand-washing basins, door locks, light bulbs, and exhaust fans. The floors are made of non-slip materials and have sound insulation functions. This type of toilet has a prefabricated structure, is suitable for multi-field scenarios, and covers seven prefecture-level cities in Tibet, including Lhasa City, Qamdo City, and Ngari City. Its core advantage lies in its rapid deployment capability. The 5-day delivery cycle can meet urgent needs, and the customization service can adapt to the space and functional requirements of different sites.
Ecological toilet mobile public toilets for scenic spots focus on adaptability to special environments. Their operating principle breaks away from traditional pipeline network dependence and achieves source separation of liquid and solid waste through toilet design. The liquid part is directed into an independent evaporation or filtration unit for treatment, while the solid part uses biodegradable materials combined with forced ventilation technology to accelerate the decomposition of organic matter into stable humus or reduce its volume through low-temperature dehydration and solar assistance. This type of toilet does not require flushing, generates no traditional sewage, and its mobility allows it to flexibly adjust its layout according to tourist flow and ecological sensitivity in scenic spots, reducing long-term environmental impacts on fixed plots. However, due to processing capacity limitations, it is more suitable for outdoor scenic spots with dispersed tourist flows.
For the special high-altitude environment, Lhasa outdoor mobile toilets need to address multiple challenges in design and operation. In a low-pressure environment, pressure-assisted or vacuum suction systems are used to ensure the smooth discharge of excrement. Strong ultraviolet rays and large temperature differences require the use of polymer materials with a high proportion of ultraviolet stabilizers for the outer shell and internal components, and metal parts need to match the coefficient of thermal expansion and contraction and be coated with a corrosion-resistant layer. In terms of water resource utilization, waterless or micro-flush toilet technologies are promoted, or small-scale water treatment and circulation units are integrated to reduce freshwater consumption and ensure winter freeze protection. For waste disposal, supporting transportation and treatment plans are required in remote areas. For energy supply, solar photovoltaic panels are the main source, and the energy storage system uses low-temperature-resistant batteries and is equipped with a management module to cope with inconvenient power access.
