Mobile Toilet Feces Treatment
There are various ways to treat feces in mobile toilets, with the following being common methods:
Direct Discharge and Feces Tanks: These are two relatively basic sewage disposal methods. Direct-discharge mobile toilets are usually connected to facilities such as sewers, discharging feces directly. This method is suitable for areas with a well-developed sewer system and offers convenient treatment. Feces tanks, on the other hand, collect feces in a specific tank. When the tank is nearly full, a specialized fecal suction truck is used to pump out the feces for centralized treatment. This method is commonly used in places without direct discharge conditions.
Chemical Treatment: Chemical agents are added to decompose and eliminate excreta. On one hand, chemical agents can control odors and improve the air quality inside the toilet. On the other hand, they promote the decomposition of excreta, making it easier to handle. The treated excreta can be further processed through specialized treatment equipment or flow into the sewage system for subsequent purification.
Anaerobic Digestion: An anaerobic digestion system is utilized to allow microorganisms to decompose and digest excreta. During this process, biogas is generated, which can be used as an energy source, such as for power generation or heating. At the same time, fertilizer is produced, which can be used in agriculture or horticulture, achieving resource recycling. Moreover, this method reduces the volume of feces and delays the need for treatment, making it suitable for situations where one is away from treatment facilities for an extended period.
Compression and Storage: Specialized equipment is used to compress excreta, reducing its volume and thus delaying the need for treatment. This treatment method is suitable for occasions such as camping or construction sites in the wild where one is away from treatment facilities for a long time. It allows for the storage of more feces in a limited space, and centralized treatment can be carried out upon returning to a place with treatment conditions.
Multi-functional Sewage Outlets: These are equipped with manual cleaning functions, such as setting up feces storage tanks or pre-burying septic tanks. Regular manual cleaning is required to store and then centrally treat the feces, ensuring the cleanliness and hygiene of the toilet and preventing the accumulation of feces from generating odors and breeding bacteria.
Mechanical Treatment: Specialized equipment is used for solid-liquid separation, decomposition, and disinfection of feces. Through these treatment steps, the impact of feces on the environment can be effectively reduced, ensuring hygiene and safety, and making the treated substances more in line with environmental protection requirements.
Flush and Non-flush Suction Types: Flush-type mobile toilets may have flushing devices. Among them, the circulating flush type accelerates fermentation and decomposition through an anaerobic treatment device for fecal sewage and biological strains, reducing the number of suction operations. The non-flush suction type uses a sewage tank at the bottom of the toilet to receive excreta, which is then suctioned out when full.
Dry Packaging Type: It is speculated that this treatment method involves dry packaging of feces, although specific details are not elaborated in the search results. In addition, outdoor finished mobile toilets also have various fecal treatment methods such as waterless, vacuum, and foam types.
