Lanzhou New Area Mobile Public Toilets
Lanzhou New Area mobile public toilets feature modular design, efficient systems, intelligent management, strong environmental adaptability, and resource recycling capabilities.
Modular Structural Design: Utilizing a modular design concept, functional modules such as the base frame, sanitary fixtures, and sewage systems can be prefabricated in factories and transported to the site for assembly. Standardized connection interfaces enable the entire assembly to be completed within eight hours, requiring only basic ground leveling for setup. The mobile restrooms use high-strength aluminum alloy buckles combined with waterproof seals, with connection points secured by hex bolts and self-locking nuts, capable of withstanding wind loads of up to force seven. Wall panels feature a honeycomb aluminum sandwich structure filled with polyurethane foam for thermal insulation and soundproofing.
Efficient System Design: The water supply and drainage system adopts a self-sustaining concept, with the water supply unit consisting of a storage tank, pressure pump, and UV disinfection device, while the drainage system employs vacuum collection technology. Waste undergoes closed-loop biological degradation and solid-liquid separation in treatment chambers, converting it into reclaimed water and organic fertilizer. The air circulation system combines negative pressure extraction with natural ventilation, featuring low-noise exhaust fans on the roof and concealed vents on the side walls. During off-peak hours, solar-powered ventilation fans maintain basic airflow, keeping internal ammonia levels below 0.3 milligrams per cubic meter.
Intelligent Management for Optimized Efficiency: Built-in infrared sensors track restroom usage, enabling cleaning staff to schedule maintenance based on peak data. The lighting system employs motion and light sensors for联动 control (combined control), limiting daily energy consumption per mobile restroom to under three kilowatt-hours and reducing water usage by approximately 60% compared to traditional flush toilets.
Strong Environmental Adaptability: Walls utilize phase-change materials to balance indoor temperature fluctuations, while all metal components undergo dual anti-corrosion treatment with anodizing and powder coating, ensuring normal operation in temperatures ranging from -20°C to 45°C.
Resource Recycling: Solid-liquid separation devices compress solid waste into block fertilizers, while the liquid portion undergoes three-stage filtration to meet agricultural irrigation standards. Biogas generated during processing serves as backup energy for the hot water system, with the entire treatment cycle converting approximately 85% of waste into reusable resources.
