Mobile Toilet with Fecal Storage Tank

A mobile toilet with a fecal storage tank is an environmentally friendly sanitation facility suitable for places lacking fixed sewage disposal facilities, featuring mobility, easy installation, and environmental protection and energy efficiency.

1. Core Design Principles

Mobile toilets with fecal storage tanks typically adopt waterless flushing suction-type or dry packing-type designs, achieving fecal collection through built-in fecal sewage storage tanks (or disposal devices). The waterless flushing design uses gravity or mechanical devices to directly guide feces into the storage tank, eliminating the water demand of traditional flushing toilets; the dry packing-type uses biodegradable film bags to seal and package feces, reducing odor diffusion. The capacity of the storage tank is designed according to the usage scenario, generally able to accommodate the excreta of dozens to hundreds of people. When full, it can be transported by specialized vehicles or have the tank replaced for treatment.

2. Applicable Scenarios and Advantages

Such toilets are mainly used in areas lacking fixed sewage pipes, such as large construction sites, tourist attractions, temporary event venues, and post-disaster relief areas. Their core advantages include:

• Mobility: The main structure often uses a steel frame combined with lightweight and corrosion-resistant materials like galvanized steel sheets and stainless steel sheets, facilitating overall lifting or split transportation;
• Environmental protection and energy efficiency: There is no need to connect to municipal water supply and drainage systems, reducing water consumption and sewage discharge, in line with the concept of green buildings;
• Flexible combination: Dimensions, door and window positions, and internal circuits (such as lighting and ventilation systems) can be customized according to needs, supporting independent use of a single toilet or series connection of multiple toilets;
• Strong adaptability: Equipped with anti-slip floors, thermal insulation layers, and exhaust devices internally, they can operate stably in low-temperature, high-altitude, or humid environments.

3. Structure and Functional Details

• Main frame: Primarily made of steel to ensure overall strength and wind resistance. Some products adopt a modular design for quick assembly and disassembly;
• Exterior wall materials: Commonly use galvanized steel sheets, stainless steel sheets, or aluminum-plastic panels, combining durability and aesthetics. Some high-end models use double-layer sandwich panels to improve thermal insulation performance;
• Internal configuration: Standard equipment includes anti-slip floors, stainless steel toilets, exhaust fans, and lighting systems. Some products add deodorization devices, handrails, or barrier-free designs;
• Fecal storage system: Sealed design prevents leakage, and some models are equipped with liquid level alarm devices for timely cleaning.

4. Maintenance and Cleaning

When the fecal storage tank is full, it needs to be transported by specialized vehicles to a sewage treatment plant or have the tank replaced. The film bags of dry packing-type toilets need to be replaced regularly to ensure hygiene. Daily maintenance includes regular disinfection and inspection of circuits and ventilation systems to extend the service life.
