Sewage Discharge Mobile Toilet

There is currently no highly unified and detailed definition for sewage discharge mobile toilets, but they can generally be understood as types of mobile toilets that possess certain sewage collection and treatment discharge functions. Common types include water-flush and non-water-flush suction types, circulating water-flush types, dry-packing types (some of which can be classified under sewage discharge types), and foam-blocking types, among others.

Water-flush and Non-water-flush Suction Mobile Toilets: Water-flush mobile toilets store clean water in tanks and use water to flush feces and other waste into collection containers or septic tanks below. Non-water-flush suction types, on the other hand, do not use water for flushing but rely on suction equipment to draw feces and other waste into dedicated collection containers. Both methods require regular cleaning and transportation of the collection containers to appropriate disposal sites, such as sewage treatment plants or designated fecal disposal points, to achieve waste discharge and treatment.

Circulating Water-flush Mobile Toilets: This type of mobile toilet is equipped with a sewage purification treatment system. It first collects used sewage and then subjects it to a series of treatment processes, including filtration, sedimentation, and disinfection, to purify the sewage. The purified water is then reused for flushing, achieving water resource recycling. However, after prolonged use, there will still be a certain amount of residual waste that needs to be discharged, and this waste is also treated in accordance with relevant regulations.

Dry-packing Mobile Toilets: Dry-packing mobile toilets use biodegradable packing bags to collect feces. When the packing bag is full, it is sealed and removed, and a new packing bag is installed. Although their main feature is the lack of water for flushing and the packaging of feces, in some cases, they can also be regarded as a type with sewage discharge functions because the packed feces bags need to be transported to appropriate locations for harmless treatment, which also falls under the category of waste discharge treatment.

Foam-blocking Mobile Toilets: They use foam generated by a foaming device to block the sewage outlet, preventing odor from escaping. At the same time, the foam acts as a lubricant, allowing feces to slide smoothly into the collection container. The feces in the collection container also require regular cleaning and discharge, usually being transported to designated disposal sites for treatment.
