Mobile Toilet Treatment

There are various treatment methods for mobile toilets, mainly including sewage outlet connections, different types of sewage treatment, and multiple fecal treatment techniques.

The sewage outlet of a mobile toilet is typically located at the rear of the toilet, equipped with a 110 sewage pipe and a 25 water inlet pipe, which can be connected and used immediately upon landing. This is its basic hardware configuration.

Based on sewage treatment methods, mobile toilets can be classified into water-flush and non-water-flush suction types, circulating water-flush types, etc. Water-flush mobile toilets may be equipped with water-flush devices that flush excreta into the sewage system through water flow; non-water-flush suction types use a sewage tank at the bottom of the toilet to receive excreta, which requires regular suction and cleaning; circulating water-flush types use anaerobic treatment devices for fecal sewage and biological bacteria to accelerate fermentation and decomposition, reducing the number of suction operations and achieving water resource recycling.

The fecal treatment methods for simple mobile toilets are even more diverse:

• Chemical treatment: Chemical agents are used to decompose and eliminate excreta, control odors, and promote decomposition. The treated excreta can be further processed through specialized equipment or discharged into the sewage system for centralized treatment.
• Anaerobic digestion: Anaerobic digestion systems are utilized to decompose and digest excreta through microorganisms, producing biogas (usable for energy) and fertilizer (usable for agriculture or horticulture). This method reduces the volume of excreta, delays treatment needs, and is suitable for scenarios where one is away from treatment facilities for extended periods.
• Compression and storage: Compression and storage are used to reduce the volume of excreta and delay treatment needs. This method is suitable for scenarios such as camping or construction sites in the wild where one is away from treatment facilities for extended periods.
• Multi-functional sewage outlet: Equipped with manual cleaning functions, such as fecal storage tanks or pre-buried septic tanks. Manual cleaning is required to store and then centrally process feces, with regular cleaning needed to maintain cleanliness and hygiene.
• Mechanical treatment: Specialized equipment is used for solid-liquid separation, decomposition, and disinfection, reducing the impact on the environment and ensuring hygiene and safety.

In addition, outdoor finished mobile toilets also have various fecal treatment methods such as waterless, vacuum, and foam types, suitable for specific scenarios such as cultural tourism projects in scenic spots. These treatment methods each have their own characteristics, and the appropriate type of mobile toilet and treatment method can be selected based on actual needs and usage environments.
