Simple Mobile Waterless Toilet

A simple mobile waterless toilet is a toilet facility that can be moved as a whole, requires no external water supply, and treats feces through specific methods. The following is an introduction from aspects such as its types, structure, and working principle:

Types

According to the sewage treatment method, mobile toilets include various types. A simple mobile waterless toilet may belong to the waterless flushing suction type or the dry packing type. A waterless flushing suction-type mobile toilet does not require water for flushing. It collects feces into a storage container through a suction device for subsequent centralized treatment. A dry packing-type mobile toilet uses biodegradable packing bags to directly pack the feces, preventing feces from coming into contact with the outside environment. When treating it, one only needs to take out the packing bag.

Structural Composition

A simple mobile waterless toilet generally has some basic structures. Although the structures of toilets of different types and designs may vary, they usually have a feces storage device for collecting and storing feces, such as the storage tank of the waterless flushing suction type or the packing bag placement area of the dry packing type. There are also sanitary fixtures like squat pans or toilet seats for users to use. Some simple mobile waterless toilets are equipped with hand-washing facilities. However, since they are waterless toilets, the hand-washing water may be provided through an internal circulation system or come with a limited water supply. The walls and roof form a closed space for the toilet, ensuring the privacy and safety of users, while the floor provides stability and comfort during use. In addition, to facilitate movement, it is also equipped with moving devices such as wheels.

Working Principle

Taking a dry packing-type simple mobile waterless toilet as an example, when a user finishes using the toilet, the feces directly fall into the biodegradable packing bag. After use, there is no need for water flushing; one only needs to seal the packing bag well. When the packing bag is full or needs to be cleaned, the staff takes out the packing bag and replaces it with a new one. The waterless flushing suction type uses a specific suction device to suck the feces from the squat pan or toilet seat into the storage tank. When the storage tank is full, it is transported away for treatment by a professional vehicle.
