Installation of Mobile Toilets in Rural Areas of Gannan
The installation of mobile toilets in rural areas of Gannan needs to take into account the characteristics of high-altitude and cold regions, with a focus on technical adaptability, environmental adaptability, and post-installation maintenance. Currently, publicly available information does not provide specific steps, but the following key points can be summarized:

I. Technical Adaptability Design
The Gannan region has high altitudes, deep permafrost layers, and is ecologically sensitive. Mobile toilets should adopt a modular structure for rapid deployment during non-permafrost periods, minimizing ground excavation and ecological damage. Biodegradable toilets require the addition of insulation layers (such as polyurethane foam) to maintain microbial activity. Vacuum collection systems reduce water usage through negative pressure suction, avoiding malfunctions caused by freezing in traditional flush toilets due to low temperatures. Some projects use a 'dry-wet separation' technique, storing excreta separately from treatment media to reduce winter treatment difficulties.
II. Installation Environment Optimization
- Material Resistance: Due to strong ultraviolet radiation and large temperature differences between day and night on the plateau, the outer shell should be made of anti-aging composite materials (such as fiberglass or modified plastics) to prevent cracking from prolonged exposure to sunlight.
- Energy Supply: Leveraging Gannan's advantage of over 2,500 hours of annual sunshine, solar power systems should be prioritized to provide energy for electric heating tapes, lighting, and other equipment, reducing reliance on the power grid.
- Anti-Freezing Measures: The piping system should be wrapped with electric heating tapes, controlled by thermostats for automatic start and stop. The bottom of the fecal storage tank should be equipped with floor heating or heat pumps to prevent excreta from freezing and affecting cleaning.
III. Dynamic Maintenance and Layout Adjustment
Based on seasonal fluctuations in tourist numbers (such as a surge in demand during the summer tourism peak), real-time analysis of usage frequency through crowd monitoring devices (such as infrared sensors or cameras) is necessary to dynamically adjust toilet distribution. For example, the Zhagana Scenic Area adds temporary modular toilets during peak seasons and reduces their number during off-seasons to lower maintenance costs. Daily maintenance involves regular inspection of electric heating tape systems, cleaning of fecal storage tanks, and spraying of biological agents to accelerate decomposition.
IV. Corporate Service Support
Companies such as Yan'an Spire Energy Conservation and Environmental Protection Technology Co., Ltd. offer full-process services including 'design-installation-after-sales'. Their project cases indicate that the cooperation process includes on-site surveys, customized design solutions, standardized construction (such as foundation leveling, module assembly), and operational training. However, specific installation steps (such as pipe slope, electrical wiring specifications) should refer to the operation manuals provided by the company or contact technical personnel for guidance.
Recommendation: For detailed installation guidelines, contact local environmental protection technology companies to obtain technical documents or refer to national standards such as the 'Installation Specifications for Mobile Toilets in High-Altitude and Cold Regions' (e.g., GB/T 38837-2020) to ensure construction complies with safety and environmental requirements.
