Outdoor Wooden Mobile Toilet Sewage Disposal
Common sewage disposal methods for outdoor wooden mobile toilets include water-flush and non-water-flush suction types, circulating water-flush types, dry packing types, sewage tank collection and treatment, biochemical degradation treatment, and water recycling treatment, etc.. Details are as follows:
Water-flush and non-water-flush suction types: Water-flush mobile toilets are equipped with a water-flush device. The water tank is usually placed on top of the toilet, and sewage is discharged into a sewage tank at the bottom. When the sewage tank is full, it needs to be suctioned out in a timely manner. Non-water-flush types do not have a flushing device. Excreta is directly received by the sewage tank at the bottom, which also requires regular suction. This method is suitable for places with a water source and convenient suction operations, such as city parks and scenic spots.
Circulating water-flush type: This type of mobile toilet is equipped with intermittent aerobic and anaerobic treatment devices. Biological strains are added, and the biological membrane technology is used to accelerate the fermentation and decomposition of fecal sewage. Then, the treated water is recycled through a filtration device for flushing toilet fixtures. This method can effectively save water resources and is suitable for areas with a scarcity of water resources or high environmental protection requirements.
Dry packing type: Without a water-flush device, excreta is received by a biodegradable plastic bag at the lower part of the toilet fixture. A new plastic bag is automatically replaced after each use, and after use, it is collected and transported to a treatment plant for disposal. This method does not require a water source, and the plastic bags are biodegradable, which is environmentally friendly. It is suitable for arid areas or temporary event venues.
Sewage tank collection and treatment: Most simple mobile toilets are equipped with sealed sewage tanks. Sewage is directly discharged into the tank and regularly transported by professional vehicles to urban sewage treatment plants for centralized treatment. This method is simple to operate and suitable for various scenarios, but it is necessary to ensure the airtightness of the sewage tank to prevent odor leakage.
Biochemical degradation treatment: Built-in biochemical treatment devices are used to decompose organic matter in sewage through microbial strains, converting feces and flushing water into harmless water and gases (such as carbon dioxide). The treated water can meet emission standards. This method is environmentally friendly and efficient and is suitable for places with high emission requirements.
Water recycling treatment: Sewage reuse is achieved through a filtration and disinfection system. First, physical filtration is used to remove impurities, and then chemical disinfection is used to kill bacteria. The treated water is used for toilet flushing. This method can effectively save water resources and is suitable for areas with a water shortage.
