Mobile Toilet Fecal Tank Treatment
There are various methods for treating fecal tanks in mobile toilets, including water-flush and non-water-flush suction types, multi-functional drainage ports with manual cleaning, dry packing types, mechanical treatment, chemical treatment, anaerobic digestion, and compression and storage.
Water-flush and Non-water-flush Suction Types: Water-flush mobile toilets are equipped with a water-flushing device, with a water tank placed on top and a sewage tank at the bottom; non-water-flush types have no flushing device, and the sewage tank at the bottom directly receives excrement. For both types, the sewage tank has a relatively small capacity and needs to be suctioned promptly when reaching the specified number of users to prevent overflow, resulting in a high suction frequency.
Multi-functional Drainage Ports with Manual Cleaning: Some mobile toilets are equipped with manual cleaning functions, such as fecal storage tanks or pre-buried septic tanks. Regular manual cleaning is required to store and centrally process the feces to maintain toilet cleanliness and hygiene.
Dry Packing Type: This type of mobile toilet has no water-flushing device, and excrement is received by a biodegradable plastic bag at the lower part of the sanitary fixture. Each time a person uses it, a new plastic bag is automatically replaced. After use, the bags are collected and transported to a treatment plant for disposal, which is environmentally friendly and convenient.
Mechanical Treatment: Specialized equipment is used to separate solids from liquids, decompose, and disinfect feces. This method can effectively reduce the impact on the environment while ensuring hygiene and safety, suitable for occasions with high environmental protection requirements.
Chemical Treatment: Chemical agents are used to decompose and eliminate excrement, control odors, and promote decomposition. The treated excrement is further processed through specialized equipment or flows into the sewage system, suitable for occasions requiring rapid treatment with minimal environmental impact.
Anaerobic Digestion: Anaerobic digestion systems are used to treat excrement, where microorganisms decompose and digest it to produce biogas and fertilizer. Biogas can be used as an energy source, and fertilizer can be used in agriculture or horticulture, reducing volume and delaying treatment needs, suitable for situations where leaving the treatment facility for an extended period is necessary.
Compression and Storage: The volume of excrement is reduced through compression and storage, delaying treatment needs. Suitable for occasions such as camping or construction sites in the wild where leaving the treatment facility for an extended period is necessary, effectively solving the problem of excrement treatment.
