Yichang Construction Site Mobile Toilets for Public Restrooms

The mobile toilet rental service for construction sites in Yichang centers around a non-pipeline-based excreta treatment system, achieving efficient and environmentally friendly supply of temporary sanitation facilities through modular design. Its technical principles and functional features are as follows:

I. Basic Unit Composition and Material Characteristics

The mobile public toilet consists of three parts: the box structure, the sewage storage container, and the circulating flushing system.

• Box Material: High-density polyethylene or fiberglass-reinforced plastic is used. High-density polyethylene has strong resistance to temperature-induced deformation, making it suitable for outdoor environments; fiberglass-reinforced plastic has high impact resistance, capable of withstanding collision risks at construction sites.
• Structural Sealing: The box is formed through an integrated molding process to ensure sealing, preventing odor leakage while being corrosion-resistant and easy to clean.

II. Sewage Storage Container and Intelligent Management

The sewage storage container is the core module for excreta treatment. Unlike traditional septic tanks, its function is closed storage rather than biochemical degradation.

• Capacity and Removal Cycle: The standard single sewage storage box has a volume of 1.5-2 cubic meters and can maintain 3-4 days without removal under the condition of an average daily usage of 150 people.
• Intelligent Warning System: The box is equipped with a liquid level sensor inside. When the sewage volume reaches 80%, a warning is triggered, and a sewage suction truck is dispatched for external treatment to avoid overflow risks.

III. Circulating Flushing System and Water-Saving Technology

To reduce water consumption, the mobile public toilet adopts two mainstream technologies:

• Foam Sealing Technology: Foam is generated by a foaming agent to fill the toilet pipes, lubricating the pipes and isolating odors. The water consumption is only 1/10 of that of traditional flushing, with a single flush of 0.1-0.2 liters.
• Packaging Technology: A mechanical device is used to seal excreta into biodegradable plastic bags, which are independently packaged and fall into a collection box. No external water source is required, making it suitable for water-scarce environments, although the cost per bag is slightly higher than that of the foam sealing type.

IV. Climate Adaptability Design

In response to extreme weather conditions, the mobile public toilet is equipped with a dual protection mechanism:

• Winter Anti-freezing: Self-limiting heating cables are wound around the outer wall of the pipes. When the temperature drops below 5℃, the thermostat automatically powers on to maintain the pipe temperature above 10℃.
• Summer Deodorization: Biological enzyme preparations are added to the sewage storage box to decompose organic matter and inhibit anaerobic gas production. At the same time, odor is adsorbed through a top ventilation fan and an activated carbon filter device to ensure a clean environment.

The mobile toilets at construction sites in Yichang achieve efficient management of temporary sanitation facilities through modular design, intelligent monitoring, and water-saving technology, providing an environmentally friendly and economical solution for construction projects.
