Where Does the Sewage from Mobile Villa Toilets Go?

The destination of sewage from mobile villa toilets varies depending on their type, with the following main scenarios:

Flush-type Mobile Toilets

Flush-type mobile toilets typically have a water tank placed on top of the toilet, using water flow to flush excrement into a sewage tank located at the bottom. When the sewage tank has a small capacity, it needs to be pumped out promptly after reaching a specified number of users to prevent sewage overflow. Additionally, there is a self-priming flush-type mobile toilet, such as the type used on high-speed trains, whose rear base can be connected to a sewage pipe. This design allows sewage to be directly discharged into designated sewage pipes or septic tanks. Some self-priming flush-type mobile toilets are also equipped with fiberglass toilet bowls, further enhancing sewage discharge and treatment capabilities.

Recirculating Flush-type Mobile Toilets

Recirculating flush-type mobile toilets employ advanced sewage treatment technology, equipped with intermittent aerobic and anaerobic treatment devices for fecal sewage. By adding biological strains and utilizing biofilm technology, these toilets can accelerate the fermentation and decomposition process of fecal sewage. The treated fecal sewage passes through a filtration device and, after reaching a certain cleanliness standard, is recirculated for flushing toilet fixtures. This design not only conserves water resources but also reduces sewage discharge, making it more environmentally friendly.

Dry-pack Mobile Toilets

Dry-pack mobile toilets do not have a flushing device; instead, excrement is collected in biodegradable plastic bags placed beneath the toilet fixtures. After use, these bags containing excrement are collected and transported to specialized treatment plants for disposal. This treatment method avoids the generation and discharge of sewage, making it suitable for areas with scarce water resources or high environmental requirements. Additionally, the use of biodegradable plastic bags reduces environmental pollution, aligning with the concept of sustainable development.
