Ezhou Construction Site Portable Toilet Design

The design of portable toilets for construction sites in Ezhou focuses on temporary sanitation solutions, meeting site demands through modular, water-saving, environmentally friendly, and adaptive designs. The main features are as follows:

1. Independent Operating System

Portable toilets are essentially miniature sewage collection and treatment units, consisting of a sewage storage tank, a flushing circulation device, and an odor removal system. The sewage storage tank is made of high-density polyethylene, which is resistant to acid-base corrosion and ultraviolet aging, effectively preventing sewage leakage. The flushing system is triggered by foot pedal or hand pressure, with each flush using only 0.3 to 0.5 liters of water, just one-tenth of that used by household toilets, significantly reducing water consumption.

2. Odor Removal and Environmentally Friendly Design

The odor removal system uses activated carbon filters to adsorb odor molecules such as hydrogen sulfide and ammonia. Meanwhile, the sewage storage tank is pre-loaded with biodegradable bacteria agents that decompose organic matter and inhibit odor production. The flushing circulation device and the sewage storage tank form a closed-loop system, reducing sewage discharge and meeting environmental protection requirements.

3. Structural and Adaptive Optimization

The frame is made of lightweight steel, balancing stability and ease of transportation. The interior is divided into functional areas equipped with sanitary fixtures, a water supply tank, and a ventilation system. The independent chassis can be placed directly on compacted and leveled soil or concrete pads without the need for drainage ditch excavation or pipe pre-embedding. The bottom is equipped with adjustable support legs that can adapt to slope differences of up to 3 degrees, making it suitable for complex terrains.

4. Modularization and Rapid Deployment

Components are prefabricated in the factory and then assembled on-site, reducing long-term occupation of the construction site. Rental specifications include single-person squatting units (approximately 80 kilograms) and double-person squatting units (approximately 120 kilograms), both equipped with lifting rings or forklift slots for easy on-site transportation. The modular design supports quick assembly and disassembly, meeting the dynamic needs of construction sites.

5. Enhanced Environmental Adaptability

Winter freeze protection relies on the physical properties of the materials. The sewage storage tank adopts a double-layer structure filled with a 3-centimeter-thick polyurethane foam insulation layer, and the flushing pipes are equipped with freeze-proof spring valves. In cold or rainy and humid regions, additional insulation layers, rust-proof treatments, and anti-slip measures on the ground are required to ensure stable operation of the equipment in extreme environments.

6. Convenient Maintenance and Management

The capacity of the sewage storage tank is designed according to usage frequency and requires vacuum sewage trucks to remove waste every 3 to 7 days. After pumping, clean water is injected and biodegradable bacteria agents are added. Cleaning tasks include internal disinfection, ventilation checks, and hardware maintenance, with the cycle dynamically adjusted according to the number of workers and usage intensity to ensure sanitary conditions are met.
