Xinjiang Mobile Toilet Installation Project
The Xinjiang mobile toilet installation project requires the integration of multiple factors such as technology, environmental protection, and procurement. Here are the key points:
At the technical level, modular prefabrication technology is the core. The toilet structure is broken down into standardized components such as walls, roofs, and bases. The main manufacturing processes are completed in the factory, and on-site assembly is as simple as putting together large building blocks, enabling efficient installation. Structural sealing technology ensures the reliability of connections between modular components. The joints are filled with closed-cell foam sealing strips and covered with weather-resistant sealing adhesive layers, which can adapt to the thermal expansion and contraction of materials caused by the large temperature differences between day and night in Xinjiang. The application of lightweight materials improves installation efficiency. The color-coated steel walls use aluminum-zinc-plated steel sheets as the base material, with flame-retardant polyurethane foam filled in the middle to form a sandwich structure. The weight per square meter is controlled to be less than one-fourth of that of traditional brick-concrete structures.
In terms of environmental protection, some mobile toilets are equipped with vacuum collection devices that use air pressure differences to transport waste. Each flush requires only 0.5 - 0.8 liters of water, saving more than 85% of water compared to traditional flushing methods. For waste treatment, microbial decomposition technology is introduced. Specific microbial communities convert organic waste into carbon dioxide, water, and a small amount of humus in temperature-controlled tanks, with a conversion rate of over 90%. The end products can be used as soil amendments for desert vegetation restoration. The surface coating of the color-coated steel sheets provides up to 20 years of corrosion protection. The steel recycling rate can reach over 95%. After separation by professional equipment, the polyurethane filler can be re-prepared into chemical raw materials through thermochemical decomposition. The roof inclination angle is calculated to reserve a light-collecting surface for the installation of photovoltaic panels. Monocrystalline silicon solar panels combined with an energy storage system can meet basic functional requirements such as lighting, ventilation, and winter electric tracing. During installation, a suspended foundation is used, eliminating the need for foundation excavation. After the support brackets are removed, the ground surface can quickly return to its natural state.
Regarding procurement projects, the finished mobile toilet procurement project of the Party School (Administrative College) of the CPC Xinjiang Uygur Autonomous Region involves the purchase of 2 sets, with a budget amount and maximum price limit of 600,000 yuan each. The contract performance period is within 60 days after the contract is signed. The mobile toilet procurement project of the Xinjiang Uygur Autonomous Region Department of Culture and Tourism includes the procurement of mobile toilets for the S101 tourist highway, the Tasha Ancient Road, etc. The winning suppliers include Liaoning Jiayi Technology Co., Ltd. and Nanjing Xinzhifa Integrated Housing Technology Co., Ltd.
