Baisha Prefabricated Mobile Toilet
The Baisha prefabricated mobile toilet, provided by Dalian Maipu Technology Co., Ltd., is a modular sanitation facility applied in Baisha Li Autonomous County, featuring efficient water conservation, rapid deployment, and strong environmental adaptability.
Technical Principles and Core Components: This toilet employs an integrated water circulation system that achieves solid-liquid separation through three-stage filtration (coarse filtration, fine filtration, and biofilm treatment). The purified water can be recycled for toilet flushing, achieving an average daily water-saving rate of 80%. The main structure is constructed from high-strength fiberglass-reinforced plastic or a metal frame, incorporating a moisture-resistant ceiling design. Internally, it is equipped with basic electrical modules such as a distribution box and switch sockets, while optional components like washbasins and lighting systems can be selected based on demand. The treatment unit adopts a sealed design, with a sewage storage tank capacity ranging from 500 to 2000 liters, supporting a 7-15 day maintenance-free cycle and effectively preventing odor diffusion.
Usage Scenarios and Adaptability: The equipment can operate stably within a temperature range of -20°C to 50°C, with a sun-resistant coating extending the shell's lifespan to 10-20 years. Differentiated configurations are available for various scenarios: scenic areas can opt for a wood-grain finish to blend with the environment; mountainous regions utilize reinforced foundation modules to cope with complex terrain; waterless areas achieve independent water supply by adding water storage tanks. The mobile methods include integral hoisting (with a single unit weight of 1.5-3 tons) and split transportation, allowing delivery to designated locations via flatbed trucks or helicopter hoisting to meet deployment needs in remote areas.
Technical Highlights and Actual Performance: Compared to traditional brick-and-mortar public toilets, the construction period is shortened from 30 days to 3 days, eliminating the need for underground pipeline excavation. Based on a daily usage of 100 people, only 1-2 tons of fresh water need to be replenished monthly; biodegradation technology reduces fecal volume by over 60%, lowering subsequent treatment costs. The integrated electrical system is powered by a 380V industrial power supply, equipped with leakage protection devices, and maintains a fault rate below 0.5% in high-frequency scenarios with 200 daily uses, complying with outdoor electrical safety standards.
Maintenance and Sustainability: Daily maintenance only requires weekly cleaning of the solid residue tank and quarterly replacement of the filtration membrane, with free replacement of spare parts provided during the 3-year warranty period. The modular design supports localized repairs, with individual component replacement taking no more than 2 hours. After retirement, 90% of the materials can be recycled and reused, reducing construction waste. Some models are equipped with solar panel auxiliary power systems, enabling energy self-sufficiency in areas with sufficient sunlight and further reducing operational costs.
