Mobile Toilet for Construction Sites in Ezhou

The mobile toilet for construction sites in Ezhou is a temporary sanitation facility built on a 'non-fixed sewage discharge system'. It operates independently through the coordinated work of a sewage storage tank, a flushing circulation device, and an odor removal system, demonstrating strong environmental adaptability.

Core Structure and Functions

1. Sewage Storage Tank: Made of high-density polyethylene, it is resistant to acid and alkali corrosion as well as ultraviolet aging, preventing soil contamination from sewage leakage. The tank has a double-layer structure with a 3-centimeter polyurethane foam insulation layer between the inner and outer walls, delaying freezing at low temperatures and ensuring the flow of sewage in winter.
2. Flushing System: Triggered by foot pedal or hand pressure, it uses 0.3-0.5 liters of water per flush (only 1/10 of that used by a household toilet), achieving water conservation by optimizing the water tank pressure and nozzle aperture. The pipes are equipped with anti-freezing spring valves that automatically drain residual water when the water pressure disappears, preventing damage from ice expansion.
3. Odor Removal System: It employs a composite principle of physical adsorption and chemical neutralization. Activated carbon filters adsorb odor molecules such as hydrogen sulfide and ammonia; pre-installed biodegradable agents in the sewage storage tank decompose organic matter and inhibit odor production, maintaining odor concentration below the human olfactory threshold even in high-temperature environments.

Advantages for Construction Site Scenarios

1. Independent Chassis Structure: No need to excavate drainage ditches or pre-embed pipes; it can be directly placed on compacted plain soil or concrete pads. The bottom is equipped with adjustable support legs that can adapt to ground slope differences within 3 degrees.
2. Specifications and Transport Convenience: It offers single-person (about 80 kilograms) and double-person (about 120 kilograms) squatting specifications, all equipped with lifting rings or forklift slots for rapid transport by tower cranes or forklifts, meeting the frequent adjustment needs of construction sites.
3. Sewage Treatment Process: The rental company dispatches vacuum sewage suction trucks every 3-7 days to operate. They connect a dedicated hose to the sewage discharge valve and use negative pressure to suction the mixture from the sewage storage tank. The sewage discharge valve adopts a self-locking quick connector that automatically closes after disconnection to prevent dripping. After suction, clean water and biological agents are injected to maintain the odor removal function.

Selection and Usage Considerations

1. Scale Matching: Determine the quantity based on the number of users and duration of use to avoid inconvenience or additional costs due to insufficient quantity.
2. Site Conditions: For soft ground, choose models with wheels; near water sources, opt for water-flush types; in waterless environments, prioritize packaged types; for mountain projects, pay attention to equipment volume, as narrow mountain roads may require disassemblable structures.
3. Additional Services: Prioritize service providers that offer delivery, installation, waste disposal, and emergency fault handling to reduce comprehensive costs.
