Solutions for Mobile Toilet Waste Disposal
There are various solutions for disposing of waste in mobile toilets, including water-flush, vacuum suction, biodegradation, chemical treatment, anaerobic digestion, compression and storage, multi-functional drainage outlets, mechanical treatment, waterless suction, recirculating water flush, dry packing, and foam sealing methods.
Water-flush: Sewage is discharged into municipal sewage networks or septic tanks through pipelines. The sewage system design must comply with relevant national standards. The toilet is equipped with a water-flush device, with a water tank placed on top and a sewage tank at the bottom, suitable for areas with a well-established sewage system.
Vacuum suction: A vacuum system is used to suck excreta into storage containers. Although the specific treatment process is not detailed, it is suitable for situations requiring rapid cleaning and high hygiene standards.
Biodegradation: Microorganisms are used to decompose excreta, such as in microbial mobile public toilets. Through a solid-liquid separation device, feces enter a fermentation tank and are decomposed into carbon dioxide and water, while urine is filtered and enters a comprehensive treatment system, with a degradation rate of ≥99%, making it environmentally friendly and efficient.
Chemical treatment: Chemical agents are used to decompose and eliminate excreta, control odors, and promote decomposition. The treated excreta is further processed through specialized equipment or flows into the sewage system, suitable for situations requiring high hygiene standards and rapid treatment.
Anaerobic digestion: An anaerobic digestion system is used, where microorganisms decompose excreta to produce biogas and fertilizer. Biogas can be used for energy, and fertilizer can be used for agriculture or horticulture, reducing volume and delaying treatment needs, achieving resource recycling.
Compression and storage: The volume of excreta is reduced through compression, delaying treatment needs. Suitable for situations where one is away from treatment facilities for extended periods, such as camping or construction sites in the wild, but regular cleaning is required to maintain hygiene.
Multi-functional drainage outlets: Equipped with feces storage tanks or pre-buried septic tanks, requiring manual cleaning. Feces are stored and then treated collectively, suitable for areas without a sewage system, but regular maintenance is required to ensure hygiene.
Mechanical treatment: Specialized equipment is used for solid-liquid separation, decomposition, and disinfection, reducing environmental impact. Ensures hygiene and safety, suitable for situations with high environmental protection requirements.
Waterless suction: Without a flushing device, excreta is directly received by a sewage tank at the bottom of the toilet. The sewage tank has a small capacity and requires timely suction, suitable for areas with scarce water resources or temporary use.
Recirculating water flush: Equipped with intermittent aerobic and anaerobic treatment devices, adding biological strains to accelerate fermentation and decomposition. The treated sewage is recirculated for toilet flushing through a filtration device, saving water resources and reducing suction frequency.
Dry packing: Without a flushing device, excreta is received by biodegradable plastic bags. A new plastic bag is automatically replaced after each use, and after use, it is collected and transported to a treatment plant for disposal, saving water resources and facilitating waste collection.
Foam sealing: Foam generated by a foaming liquid mixture is used instead of flushing water, with the foam covering the inside of the toilet bowl to prevent odors. The system only requires collected hand-washing water to meet foaming water needs, maximizing water conservation, suitable for situations with high water-saving requirements.
