How to Handle the Disposal of Guard Booth Mobile Toilets
The sewage disposal of guard booth mobile toilets should be carried out according to the type, and regular maintenance should be conducted in compliance with environmental protection standards.
There are various sewage disposal methods for mobile toilets, mainly divided into the following categories:
Water-flush and Non-water-flush Suction Types: Water-flush toilets are equipped with built-in water-flush devices that use a small amount of water to flush excrement into the sewage tank. If the sewage tank has a small capacity, it needs to be cleaned promptly with suction equipment. Non-water-flush types directly receive excrement in the sewage tank, which also requires regular suction to prevent overflow. Both methods require professional sewage suction vehicles and are suitable for temporary events or areas without a sewage pipe network.
Recirculating Water-flush Type: Through intermittent aerobic and anaerobic treatment devices, biological bacteria are added to the system to accelerate the fermentation and decomposition of excrement. The water quality is then purified through multiple filtration devices, enabling the treated water to be recycled for toilet flushing. This method is water-saving and environmentally friendly but requires regular replenishment of bacteria and maintenance of the filtration system. It is suitable for scenarios with water scarcity or high environmental protection requirements.
Dry Packaging Type: Degradable plastic bags are used to receive excrement. After each use, a new bag is automatically replaced. When the bag is full, it is collected and transported to a professional treatment plant for disposal. This method does not require water flushing and has no sewage discharge but requires regular replacement of plastic bags and proper disposal of waste. It is suitable for water-scarce or ecologically sensitive areas.
Foam Sealing Type: A foam-generating liquid mixing device produces foam to cover the inside of the toilet bowl, replacing the flushing function. Only hand-washing water needs to be collected to meet the foam generation requirements. The foam can isolate odors and reduce the contact between excrement and air, lowering the risk of bacterial growth. However, it requires regular replenishment of the foam-generating liquid and cleaning of foam residues.
Microbial Degradation Type: Special bacteria are added to the treatment system, and microorganisms are used to decompose excrement into water and carbon dioxide. The remaining residue can be used as organic fertilizer. This method achieves zero-pollution discharge but requires control of bacterial activity and ambient temperature. It is suitable for mobile toilets used for long-term fixed purposes.
Water-flush Direct Discharge Treatment: A water-saving design (such as a 0.5-liter flushing system) is adopted, and excrement is directly discharged into a septic tank or municipal sewage system through pipes, followed by biological degradation or centralized treatment. This method relies on a well-established sewage pipe network and is suitable for urban areas or fixed locations.
Intelligent Recirculation System (Optional): Some high-end models are equipped with recirculating water treatment devices that enable wastewater reuse through filtration and disinfection. The treated water can be used for toilet flushing or irrigation. This system requires regular water quality testing and equipment maintenance and is suitable for scenarios with high requirements for resource recycling.
Precautions: The sewage system design of mobile toilets should comply with the Urban Public Toilet Design Standard CJJ14-2016 to ensure smooth and environmentally friendly sewage disposal. Regularly cleaning the septic tank, checking for pipe blockages, and preventing odor diffusion can extend the service life of the equipment and reduce its impact on the environment.
