Mobile Toilet Car Feces Driven
The feces treatment of mobile toilet cars (vehicle-mounted mobile public toilet vehicles) mainly relies on vacuum feces suction devices. Their driving method involves the vehicle-mounted engine driving the vacuum pump to operate through a power take-off, utilizing the principle of negative pressure to achieve feces collection and transportation.

Core Driving Mechanism
The feces treatment system of vehicle-mounted mobile public toilet vehicles takes the vacuum pump as the core driving component. After the vehicle engine is started, power is transmitted to the vacuum pump through the power take-off, making it operate at high speed and suck air out of the sewage tank, creating a negative pressure environment of 0.04-0.08MPa. Under the action of this air pressure difference, feces are forcibly sucked into the tank through the feces suction pipe, completing the collection process. This technology does not rely on an external power source and only requires the vehicle's own engine for driving, ensuring the independence of the equipment in scenarios without power supply.
Technical Parameters and Performance Guarantee
To support the stable operation of the vacuum system, vehicle-mounted mobile public toilet vehicles are equipped with a 251kW rated power engine and can carry a total mass of up to 18,000kg, providing continuous power for the vacuum pump. The sewage tank capacity is designed based on the usage needs of 500 people per day and is equipped with devices such as an anti-overflow valve and a liquid level sensor to prevent sewage backflow from damaging the vacuum pump. In addition, the vacuum feces suction technology reduces the amount of flushing water (saving about 80% compared to traditional toilets), enabling centralized sewage treatment and avoiding secondary pollution, which meets environmental protection requirements.
Operation Process and Scenario Adaptation
During operation, the vehicle needs to be parked steadily and connected to an external power source (or start its own generator). After starting the vacuum pump, check the tightness of the pipeline. Once no leakage is confirmed, feces suction can begin. During the discharge stage, sewage can be discharged through self-flow (using gravity) or pressurization (through compressed air) to meet the needs of different treatment facilities. This vehicle model integrates independent toilet stalls, a clean water tank, and a sewage treatment system, making it suitable for scenarios such as temporary large-scale events, disaster relief, and remote areas. Specialized feces suction vehicles, on the other hand, mainly transport feces from septic tanks and have larger tank volumes (8-20 cubic meters), serving municipal sanitation departments.
Technical Principle Summary
The vacuum feces suction device achieves efficient feces collection and transportation through negative pressure driving. Its core advantages lie in self-sufficiency in power, water conservation, environmental protection, and flexible operation. This technology has been widely applied in vehicle-mounted mobile public toilet vehicles and has become a key solution for addressing temporary toilet needs and feces treatment challenges.
