Mobile Toilet Feces Collection

The methods of collecting feces in mobile toilets vary depending on the type, mainly including self-contained fecal tanks, biodegradable types, packaging types, suction and discharge types, and others.

Self-contained fecal tanks: Some mobile toilets come with built-in fecal tanks. For example, certain mobile toilets are 1.1 meters in length and width and 2.3 meters in height, made of polyethylene plastic, and equipped with a foot-operated squat toilet inside, with the fecal tank located directly beneath the toilet. These mobile toilets do not require a septic tank or connection to water and electricity, relying on their built-in fecal and water tanks for collection and treatment of feces.

Biodegradable types: Commonly found in scenic spots, campsites, and other locations. There is a water tank beneath the squat toilet, containing 'probiotics'. After someone uses the squat toilet, the feces flow directly into the water tank through a pipe and mix with the 'probiotics'. A small mixing device inside the water tank promotes rapid bacterial reproduction, and after approximately 24 hours, the feces are decomposed into water, carbon dioxide, and a small amount of solid residue. The decomposed water is discharged through a filtration device, while the residue settles at the bottom of the container and is periodically cleaned out for use as fertilizer.

Packaging types: Often used at construction sites and temporary construction areas. These mobile toilets have a 'drawer'-like device beneath the toilet seat. After use, stepping on the pedal on the side of the drawer with your foot packages and stores the feces, which are then processed collectively. This method is simple and convenient, suitable for temporary locations.

Suction and discharge types: Suitable for large-scale events, music festivals, and other crowded and concentrated occasions. Specialized equipment is used to suction away and treat the feces, enabling rapid and effective handling of large amounts of feces and avoiding sanitation issues caused by fecal accumulation.

In addition, there are other treatment methods, such as chemical treatment, which uses chemical agents to decompose and eliminate excreta, control odors, and promote decomposition; anaerobic digestion, which utilizes microorganisms to decompose and digest excreta, producing biogas and fertilizer; compression and storage, which reduces volume and delays treatment needs; multi-functional sewage outlets equipped with manual cleaning functions such as fecal storage tanks or pre-installed septic tanks, with periodic manual cleaning; mechanical treatment, which uses specialized equipment for solid-liquid separation, decomposition, and disinfection; and flush and non-flush suction mobile toilets. Flush types may have flushing devices, while non-flush suction types directly receive excreta in a sewage tank located at the bottom of the toilet. Flush types may require higher suction frequencies, while circulating flush types accelerate fermentation and decomposition and reduce suction times through anaerobic treatment of fecal sewage devices and biological strains.
