Mobile Toilet Feces Collection

There are various methods for collecting feces in mobile toilets, mainly including sewage tank collection, gravity sewage pipe collection, vacuum collection systems, and six other methods.

1. Sewage tank collection: This is a relatively common method. A sewage tank is installed at the bottom of the mobile toilet to collect feces and sewage. When the number of users reaches a certain level or the capacity of the sewage tank approaches its limit, professional cleaning personnel are required to regularly pump it out to ensure the normal use and hygiene of the toilet.
2. Gravity sewage pipe collection: Some mobile public toilets take advantage of terrain elevation differences. Through sewage pipes with a diameter of 100 - 150 millimeters, feces rely on their own gravity to be directly discharged into the municipal sewage network. This method is suitable for locations with appropriate terrain and convenient connections to the municipal sewage network.
3. Vacuum collection system: Mobile public toilets equipped with vacuum pumps can create a negative pressure environment inside the pipes. Feces are quickly sucked into the collection tank through pipes with a diameter of 50 - 80 millimeters. Its advantages are fast collection speed and high efficiency.
4. Biodegradable plastic bag collection: Dry-packing mobile toilets use biodegradable plastic bags to receive excreta. A new bag is automatically replaced after each use, and then the collected plastic bags are transported to a treatment plant. This method is environmentally friendly and easy to clean up.
5. Foam blockage alternative collection: Foam-blocking mobile toilets use foam generated by foaming liquid to cover the inside of the toilet bowl, replacing the water-flushing function. Urine is filtered and treated into reclaimed water, reducing water consumption.
6. Biochemical treatment tank collection: Microbial mobile toilets collect feces in a biochemical treatment tank and use beneficial microorganisms to decompose them into gas and water, achieving harmless treatment of feces.
7. Vehicle-mounted treatment equipment collection: Some mobile public toilets have small treatment devices installed below them. These devices perform preliminary treatment on feces and convert them into harmless substances, facilitating mobility and on-the-spot treatment.
8. Integrated sewage treatment equipment collection: Feces and domestic sewage are collected together and treated through processes such as sedimentation, filtration, and disinfection. The treated water is then used for secondary purposes such as toilet flushing, improving water resource utilization.
9. Smart sensing discharge system collection: Sensors are used to monitor the feces storage situation. When the set threshold is reached, the discharge valve is automatically opened to discharge the feces into designated treatment facilities, achieving intelligent management.
