Ezhou Construction Site Portable Toilet

The portable toilet for construction sites in Ezhou is a temporary sanitation solution specifically designed for construction projects or temporary engineering projects, featuring independent operation, easy transportation, and strong adaptability.

Core System Components

1. Sewage Storage Tank: Located at the bottom of the toilet, it is made of high-density polyethylene, which is resistant to acid-base corrosion and ultraviolet aging. The volume typically ranges from 200 to 500 liters, capable of holding the waste generated from several to dozens of uses, without relying on municipal sewage networks.
2. Flushing System: Designed with foot-pedal or hand-press mechanisms, each flush uses only 0.3 to 0.5 liters of water, just one-tenth of that used by household toilets, effectively conserving water resources.
3. Deodorization System: It controls odors through physical adsorption and chemical neutralization principles. Activated carbon filters adsorb hydrogen sulfide and ammonia molecules, while pre-installed biodegradable bacteria agents in the sewage storage tank decompose organic matter, reducing odor concentration.

Structural and Installation Features

1. Independent Chassis Structure: It can be directly placed on compacted and leveled soil or concrete pads without the need for excavating drainage ditches or pre-embedding pipes, making installation convenient.
2. Adjustable Support Legs: They adapt to slope differences of up to 3 degrees on construction site grounds, ensuring equipment stability.
3. Transportation Design: It offers two specifications: single-person squatting positions (about 80 kilograms) and double-person squatting positions (about 120 kilograms), both equipped with lifting rings or forklift slots for easy on-site transportation via tower cranes or forklifts.

Waste Treatment Process

The lessee dispatches vacuum sewage suction trucks according to the contractually agreed cycle (usually 3 to 7 days) to connect to the sewage discharge valve at the bottom of the toilet via a dedicated hose. Using negative pressure principles, the mixture in the sewage storage tank is suctioned into the vehicle's tank. After suctioning, workers inject clean water and add new biodegradable bacteria agents to maintain system operational efficiency.

Winter Adaptability Design

1. Sewage Storage Tank Insulation: It adopts a double-layer structure with a 3-centimeter-thick polyurethane foam insulation layer between the inner and outer walls, slowing down the freezing speed of the liquid inside the tank in environments below minus 10 degrees Celsius.
2. Pipe Anti-Freezing: The flushing pipes are equipped with anti-freezing spring valves. When water pressure disappears, the springs push the pistons to discharge residual water, preventing pipe damage from ice expansion.
