Lanzhou New District Portable Toilet
The portable toilets in Lanzhou New District feature modular design, advanced technology, strong environmental adaptability, intelligent management, strong emergency response capabilities, and resource recycling. Manufacturers include Lanzhou Shiteng Metal Products Co., Ltd. and Lanzhou Keyang Traffic Facilities Co., Ltd.
Modular Design and Assembly
The portable toilets in Lanzhou New District adopt a modular design. Functional modules such as the basic framework, sanitary fixtures, and sewage systems can be prefabricated in the factory and then transported to the site for assembly. The connection interfaces of each module are standardized, allowing for complete assembly within eight hours. The key to their assembled structure lies in the node connection technology, which combines high-strength aluminum alloy buckles with waterproof seals. The connection points are secured with hexagonal bolts and self-locking nuts, enabling them to withstand wind loads of up to Force 7. The wall panels feature a honeycomb aluminum sandwich structure filled with polyurethane foam, providing thermal insulation and soundproofing.
Water Supply and Drainage and Air Circulation Systems
The water supply and drainage system design embodies a self-sustaining concept. The water supply unit consists of a water storage tank, pressure pump, and ultraviolet disinfection device. The drainage system employs vacuum collection technology, with sewage pipes only one-third the diameter of traditional pipes, achieving water-saving flushing through negative pressure suction. The air circulation system achieves air exchange through a combination of negative pressure exhaust and natural ventilation. Low-noise exhaust fans are installed on the roof, while the side walls are equipped with concealed vents featuring a labyrinth structure to prevent odor backflow, ensuring that the internal ammonia concentration remains below 0.3 milligrams per cubic meter.
Environmental Adaptability and Usage Efficiency
The phase-change energy storage materials used in the walls absorb coolness at night and release it during the day to balance indoor temperature fluctuations. All metal components undergo dual anti-corrosion treatment with anodizing and powder coating, enabling normal operation within an environmental temperature range of minus 20 degrees Celsius to 45 degrees Celsius. Usage efficiency is optimized through an intelligent management system, with the daily energy consumption of a single portable toilet controlled within three kilowatt-hours, and water consumption reduced by approximately 60% compared to traditional flush toilets.
Emergency Response Capabilities and Resource Recycling
In emergency situations, they can be rapidly delivered by road transport and operate independently for 72 hours upon arrival without external water or electricity connections. The waste treatment system achieves resource recycling, with the entire treatment process converting approximately 85% of waste into reusable resources per cycle.
