Mobile Toilet for Coach Manual

The mobile toilet for coaches is a portable sanitation facility specifically designed for long-distance coaches to address passengers' toilet needs during travel. Here is a detailed description:

I. Main Types

1. By Installation Location: Built-in types are usually located at the rear or middle of the coach, utilizing the interior space of the carriage. When in use, the partition curtain is pulled open or the partition door is closed. External types are installed at the bottom of the coach and connected to the carriage via a telescopic ladder or step, saving interior space but requiring passengers to get on and off the vehicle.
2. By Disposal Method: Storage types are equipped with collection containers that require regular cleaning. Recirculating types achieve water reuse through filtration and purification systems.
3. Simple Types: Made of biodegradable materials, they are lightweight and low-cost but have limited capacity, suitable for short-distance passenger transport.

II. Working Principle

The core components include a toilet, a fecal storage tank, a flushing system, and a ventilation system. When a passenger uses it, the flushing system releases a measured amount of water or disinfectant to flush the waste into the fecal storage tank while forming a sealed layer to prevent odor from escaping. The fecal storage tank is made of corrosion-resistant materials and contains biodegradable agents or chemical treatment agents to decompose solid waste and reduce odor production. Some high-end models are equipped with liquid level sensors that emit a warning when the fecal storage tank is nearly full. The ventilation system extracts air through an exhaust fan and introduces fresh air to eliminate odors, reduce humidity, and improve user comfort.

III. Maintenance Points

1. Daily Cleaning: Flight attendants need to regularly wipe the surfaces, replenish sanitary supplies, use dedicated disinfectants, and pay special attention to high-frequency contact areas such as handles and flush buttons.
2. Regular Emptying of the Fecal Storage Tank: This should be carried out by professionals at designated locations. The emptying frequency depends on the number of users and the capacity of the fecal storage tank, usually requiring treatment after traveling a certain distance.
3. Regular Inspection and Maintenance: Check whether the pipes are unobstructed, whether the seals are intact, and whether the flushing system is functioning properly. If any problems are found, repair them promptly.

IV. Usage Guidelines

Passengers should follow relevant regulations when using the mobile toilet, such as keeping the toilet clean and using the flushing system correctly. Specific guidelines can be found in the detailed instructions provided by the coach operator.
