Zhangye Mobile Public Toilet Installation

The installation of mobile public toilets in Zhangye requires consideration of scenario requirements, technical specifications, management processes, and environmental adaptability, with suppliers determined through bidding and modular, energy-saving, and environmentally friendly solutions employed for efficient utilization.

1. Application Scenarios and Bidding Process

Mobile public toilets in Zhangye primarily serve areas with periodic fluctuations in tourist traffic, such as the outskirts of scenic spots during peak tourist seasons (e.g., the Rainbow Danxia Scenic Area), large temporary event venues, or phased construction sites. Their installation necessitates a standardized bidding process to select suppliers. For instance, the Rainbow Danxia Scenic Area conducted a competitive negotiation bidding process, ultimately awarding the contract to Gansu Qihang Environmental Protection Technology Co., Ltd. with a project amount of 856,324.88 yuan, specifying the bid evaluation time (September 10, 2024) and the publicity period (September 11-13). The bidding process ensures that supplier qualifications, technical solutions, and costs are controllable, providing a foundational guarantee for subsequent installations.

2. Technical Implementation and Equipment Selection

Zhangye's mobile toilets adopt a modular design, integrating diverse technologies to adapt to different environments:

• Waste Treatment Technologies: These include minimal water circulation, waterless flushing, microbial degradation, or chemical treatment to achieve preliminary on-site waste treatment. For example, mobile toilets in Zhangye Park reduce sewage discharge through microbial degradation, with some models equipped with chemical treatment devices for special needs.
• Energy Supply: Independent of the municipal power grid, relying on solar panels or small energy storage devices to ensure the operation of basic functions such as lighting and ventilation, reducing dependence on traditional energy sources.
• Special Environment Adaptation: Customized waterless and electricity-free 3+1 mobile mechanical packing toilets are designed for arid and windy sandy climates, featuring outer walls made of technological industrial mechanical materials. These toilets utilize mechanical packing technology for waste treatment without the need for water flushing or electrical support, suitable for grasslands, deserts, and other areas without water and electricity.

3. Full-Cycle Management and Maintenance Processes

Post-installation management is crucial for ensuring the long-term usability of the facilities, covering aspects such as installation positioning, daily cleaning, consumable replenishment, post-evacuation disinfection, and equipment maintenance. For example, mobile toilets in Zhangye Park follow a preset periodic maintenance process, including regular removal of storage units, inspection of consumables such as degradation agents and toilet paper, cleaning of internal spaces, and ensuring the normal operation of mechanical and electrical systems, transforming “temporary facilities” into “recyclable public service nodes.”

4. Environmental Adaptability Requirements

Mobile toilets in Zhangye require additional attention to localized needs:

• Arid Climate: Priority is given to water-saving or non-water-flushing products to reduce water consumption.
• Windy Sandy Environment: Sealed structures and vent designs are adopted to block dust and sand, extending equipment lifespan.
• Ecologically Sensitive Areas: Strict evaluation of waste disposal methods is necessary to prevent secondary pollution. For example, when introducing mobile toilets in Zhangye Park, potential impacts on local soil and vegetation must be assessed, and the exterior design should harmonize with the natural landscape or cultural atmosphere to minimize visual intrusion.
