How to Clean Excrement in Mobile Toilets
There are various methods for cleaning excrement in mobile toilets, including regular suction, chemical treatment, anaerobic digestion, compression and storage, manual cleaning, mechanical treatment, flush and non-flush suction treatment, as well as centralized harmless treatment and resource recycling.
Regular Suction: Mobile toilets are equipped with a sewage tank at the bottom to collect feces and sewage. When the sewage tank reaches a certain capacity, professional cleaning personnel need to use suction equipment for regular cleaning to prevent overflow and ensure the normal use and hygiene of the toilet.
Chemical Treatment: Chemical agents are added to decompose and eliminate excreta, control odors, and promote the decomposition process. The treated excreta can be further processed through specialized equipment or discharged into the sewage system to reduce environmental impact.
Anaerobic Digestion: Microorganisms are used to decompose excreta in an anaerobic environment, producing biogas and fertilizer. Biogas can be used as an energy source, and fertilizer can be used in agriculture or horticulture. This method is suitable for situations where it is necessary to be away from treatment facilities for extended periods, such as construction sites in the wild or campsites.
Compression and Storage: The volume of excreta is reduced through compression to delay the need for treatment. This method is suitable for situations where it is necessary to be away from treatment facilities for extended periods, but regular cleaning is required to avoid hygiene issues.
Manual Cleaning: Some mobile toilets are equipped with feces storage tanks or pre-buried septic tanks that require regular manual cleaning. During cleaning, the feces should be stored and then centrally processed to ensure the cleanliness and hygiene of the toilet.
Mechanical Treatment: Specialized equipment is used for solid-liquid separation, decomposition, and disinfection of feces to reduce environmental impact while ensuring hygiene and safety. This method is suitable for situations with high hygiene requirements.
Flush and Non-Flush Suction Treatment: Flush-type mobile toilets are cleaned using a flushing device but require a higher frequency of suction. Non-flush suction-type toilets directly receive excreta in a sewage tank. Recirculating flush-type mobile toilets use anaerobic treatment and biological bacteria to accelerate fermentation and decomposition, reducing the number of suction operations.
Centralized Harmless Treatment and Resource Recycling: The suctioned feces and sewage are transported to a specialized treatment center and converted into harmless substances through biological degradation, chemical treatment, or physical treatment. The treated feces can also be converted into organic fertilizer, achieving resource recycling.
