Mobile Toilet Defecation Processing

There are various defecation processing methods for mobile toilets, mainly differing according to their design and the type of processing used. Here are several common processing methods:

1. Water-flush direct-discharge type: This method relies on a water-flush device to directly flush excrement into the sewer pipes, but it requires supporting sewage pipes and septic tanks. Its principle is similar to that of fixed toilets, where excrement is transported to the municipal sewage system or septic tank for centralized treatment through water flow. This method is suitable for places with well-established sewage facilities, such as city parks and large event venues.

2. Waterless flush packing type: Without a flushing device, it uses special packing bags to receive excrement. After use, staff seal the packing bags and transport them to designated locations for treatment, such as landfills or professional treatment plants. This method does not require a water source or sewage pipes and is suitable for areas lacking water or sewage conditions, such as arid regions and temporary construction sites.

3. Foam sealing type: By covering excrement with foaming liquid, a sealing layer is formed to reduce odors and bacterial growth. When excrement accumulates to a certain amount, a fecal suction truck sucks it away and transports it to a treatment station. This method saves water and effectively controls odors, making it suitable for places with high hygiene requirements, such as scenic spots and high-end event venues.

4. Microbial degradation type: It utilizes microbial communities to decompose excrement, separating urine and feces through a solid-liquid separation device. After entering the fermentation tank, feces are decomposed into carbon dioxide and water under the action of microorganisms, with a degradation rate of over 99%. This method is environmentally friendly and efficient, requiring no frequent cleaning, and is suitable for long-term use in mobile toilets, such as in eco-tourism areas and remote regions.

5. Recirculating water-flush type: It is equipped with intermittent aerobic and anaerobic treatment devices and adds biological strains, using biofilm technology to accelerate the fermentation and decomposition of fecal sewage. The treated water can be recycled for flushing toilet fixtures, achieving efficient water resource utilization. This method is suitable for scenarios with scarce water resources or requiring long-term use, such as desert areas and large construction sites.

6. Vacuum suction type (vehicle-mounted mobile toilets): It uses a vacuum pump to generate negative pressure and sucks excrement into a fecal collection tank. This method has a compact structure and is suitable for vehicle-mounted or mobile scenarios, such as trains, long-distance buses, and temporary events. The fecal collection tank needs to be cleaned regularly when full, but the treatment process is relatively simple.
