Fecal Cleaning Mobile Toilet
There are various fecal treatment methods for fecal cleaning mobile toilets, mainly including regular suction, centralized treatment, and several other methods.
Regular suction is the fundamental method for fecal treatment in mobile toilets. A sewage tank is usually installed at the bottom of the mobile toilet to collect feces and sewage. When the number of users reaches a certain level or the sewage tank is close to its capacity limit, professional cleaning personnel need to use suction equipment to extract the feces and sewage from the tank. This process effectively prevents the sewage tank from overflowing, ensures the hygiene and normal use of the toilet, and avoids unpleasant odors and sanitation hazards caused by fecal accumulation.
Centralized treatment is a crucial step after regular suction. The extracted feces and sewage are transported to a specialized fecal treatment center. Here, various harmless treatment methods are employed, such as biological degradation, which uses microorganisms to break down the organic matter in feces into simple inorganic substances; chemical treatment, which involves adding chemical agents to alter the chemical properties of feces and kill pathogens; and physical treatment, such as filtration and sedimentation, to remove impurities and harmful substances from feces. After these treatments, feces can be transformed into substances harmless to the environment and further converted into organic fertilizers for agricultural use, achieving resource recycling.
Other treatment methods also have their own characteristics. Chemical treatment decomposes and eliminates excreta by adding chemical agents while controlling odors and promoting decomposition. The treated excreta can be further processed through specialized equipment or discharged into the sewage system. Anaerobic digestion utilizes an anaerobic digestion system to allow microorganisms to decompose and digest excreta, producing biogas for energy and fertilizer for agriculture or horticulture. It also reduces volume and delays treatment needs, making it suitable for situations where one is away from treatment facilities for an extended period. Compression and storage reduce the volume of excreta through compression, delaying treatment needs, and are suitable for camping or construction sites in the wild. Multi-functional sewage outlets are equipped with manual cleaning functions, such as fecal storage tanks or pre-buried septic tanks, which require regular manual cleaning and centralized treatment of feces. Mechanical treatment uses specialized equipment for solid-liquid separation, decomposition, and disinfection, reducing the impact on the environment and ensuring hygiene and safety. Water-flush mobile toilets may have water-flush devices. The circulating water-flush type accelerates fermentation and decomposition through an anaerobic treatment device for fecal sewage and biological bacteria, reducing the frequency of suction; the non-water-flush suction type collects excreta in a sewage tank at the bottom of the toilet.
