Working Principle of Temporary Mobile Toilets

The working principles of temporary mobile toilets are mainly divided into two categories based on different types: modular assembly technology and independent sewage storage systems, as detailed below:

Modular assembly technology is the fundamental construction method for temporary mobile toilets. The equipment is transported in bulk form from the factory and assembled on-site using bolts or snap-on fixtures. This technology enables rapid setup and allows for flexible relocation and reconfiguration according to actual needs, making it suitable for various temporary venues such as large event sites and construction sites.

The independent sewage storage system is the core component for handling waste in temporary mobile toilets and includes several types:

• Direct Discharge (Flush) Type: These toilets come with a freshwater tank and a wastewater tank, using a foot pedal or manual pump for flushing. During use, freshwater flows from the freshwater tank to flush the toilet, while wastewater flows into the wastewater tank. This type is suitable for venues with water supply and drainage connections, providing a relatively comfortable toilet experience.
• Packaging (Waterless Flush) Type: This type uses biodegradable plastic bags to instantly package and seal waste without water flushing. After each use, a new plastic bag automatically replaces the old one, isolating waste from the outside environment. It is particularly suitable for water-scarce or environmentally sensitive areas such as arid regions and wilderness work sites.
• Foam Sealing Type: This type uses foaming agent to seal and cover waste, forming a foam layer. This foam effectively suppresses odor emissions while conserving water and being environmentally friendly.
• Vacuum Suction Type: A vacuum pump creates a negative pressure environment in the pipes, instantly sucking waste into the main pipe and transporting it to a treatment tank. This type can quickly and efficiently handle waste, reducing odor and pollution.
• Microbial Degradation Type: A degradation chamber filled with microbial carriers is installed beneath the toilet seat. Microorganisms decompose organic matter through aerobic fermentation. The high temperatures generated during decomposition kill pathogens, achieving harmless waste treatment.
• Chemical Agent Type: Chemical agents are added to the fecal storage tank to decompose waste through chemical reactions and inhibit odor and bacterial growth. This method is simple to operate but requires careful selection and dosage of chemical agents to ensure treatment effectiveness and safety.
