Where to Place Feces in Mobile Toilets
The storage location and disposal method of feces in mobile toilets depend on the type of toilet. Common storage locations include water storage tanks, sewage tanks, feces collection tanks, and biodegradable plastic bags, with disposal methods covering chemical decomposition, suction transportation, and biodegradation.
There are two main feces disposal methods for household portable or RV mobile toilets. Chemical Decomposition Type: After feces are discharged into the water storage tank, a special decomposition agent is added to convert the feces into harmless liquid through a chemical reaction, which is then poured into the sewage well. Bag Collection Type: Biodegradable plastic bags are used to collect excreta. After use, the bag opening is tightly sealed and disposed of in designated trash bins according to local waste classification rules.
The feces disposal methods for public mobile toilets are more diverse. Water-flush and Non-water-flush Suction Types: Feces are discharged into the bottom sewage tank, and professional agencies need to be contacted regularly to use special suction trucks to pump away the sewage and transport it to the treatment plant. Recirculating Water-flush Type: Fecal sewage is treated through biofilm technology, and the generated reclaimed water can be recycled for toilet flushing, reducing water consumption. Dry Packaging Type: Biodegradable plastic bags are used to collect excreta, which are then transported to the treatment plant for harmless treatment. Microbial Degradation Type: Solid feces are mixed with wood chips and bacterial strains for fermentation, decomposing into carbon dioxide and water; urine is treated to generate reclaimed water, which can be used for toilet flushing or green irrigation. Vacuum Suction Type (Vehicle-mounted Mobile Toilets): A vacuum pump is used to suck excreta into the feces collection tank, facilitating transportation to the treatment plant or designated discharge point.
Other disposal methods include Natural Treatment: Some environmentally friendly mobile public toilets treat feces through bacterial decomposition or earthworm biodeposition, achieving harmless and resourceful treatment. Septic Tank Treatment: Sedimentation and anaerobic fermentation technologies are used to purify sewage, and the treated feces can be used as organic fertilizer for agricultural planting.
When handling, compliance should be noted: Avoid pouring solid debris into the toilet to prevent pipe blockage; regularly disinfect the water tank and sewage tank to inhibit bacterial growth; tightly seal the bag opening during bag collection to prevent leakage; and comply with environmental protection regulations during transportation to avoid secondary pollution.
