Lhasa Mobile Toilet Project
The Lhasa Mobile Toilet Project includes three types: outdoor finished mobile public toilets, ecological toilets for scenic spots, and outdoor mobile restrooms. Details are as follows:
Outdoor Finished Mobile Public Toilets: The product price is 1200 yuan per unit, with a delivery time of 5 days and a total supply of 780 units. The minimum order quantity is 1 unit, and nationwide delivery is available with customization options. The products come in a variety of materials, specifications, models, and colors, with exterior dimensions made according to drawings. They are of the assembled type, featuring sound insulation and equipped with squat toilets, sinks, door locks, light bulbs, exhaust fans, etc. The floors are non-slip. The supply covers Lhasa City and multiple cities, districts, and counties in Tibet.
Ecological Toilets for Scenic Spots: The core operating principle is the immediate classification and isolation of waste, separating liquid and solid waste at the source through special toilets. The liquid is usually directed to independent evaporation or filtration treatment units; the solid waste uses biodegradable materials, combined with forced ventilation to create an aerobic environment, promoting microbial activity to accelerate the decomposition and stabilization of organic matter. It also incorporates low-temperature dehydration principles, using natural wind and solar energy to reduce the volume of the material and convert it into stable humus. Its characteristics include not producing traditional sewage, requiring little to no flushing, not relying on external water sources and sewage networks, and achieving a self-contained treatment cycle. It is more suitable for outdoor scenic spots with dispersed人流 (visitor flow), and maintenance management focuses on ensuring the effectiveness of the separation system, the smoothness of the ventilation system, and the regular inspection and replenishment of degradation media.
Outdoor Mobile Restrooms: The design needs to address geographical and climatic conditions such as low air pressure, strong ultraviolet rays, and large temperature differences. The waste disposal system uses pressure-assisted or vacuum suction systems to prevent waste retention and freezing. In terms of material selection, polymer materials for the outer shell and internal components are added with a high proportion of ultraviolet stabilizers, and metal components consider the matching of thermal expansion and contraction coefficients and corrosion-resistant coating processes. For water resource utilization and anti-freezing, waterless or micro-water flushing technologies are used, along with miniaturized water treatment and circulation units. The water pipes are equipped with electric tracing or special materials and wrapped with insulation layers. For the terminal disposal of waste, solid waste can be centrally transported or processed using on-board rapid composting devices to produce humus. Energy supply mainly relies on solar photovoltaic panels, which need to be optimally installed according to the solar radiation angle in the plateau area. The energy storage system selects low-temperature-resistant batteries and is equipped with management modules.
