Bubble Sewage Discharge Mobile Toilet

The bubble sewage discharge mobile toilet is a highly efficient, water-saving mobile toilet that utilizes foam sealing technology. It achieves waste isolation and environmentally friendly treatment through physical properties, making it suitable for outdoor scenarios.

Working Principle

When the foaming agent is mixed with water, under the action of compressed air, a large amount of fine foam is generated, covering the inner side of the toilet bowl to form a lubricating isolation layer. The foam layer effectively blocks the emission of odors, reduces the splashing of waste, and, through its lubricating effect, causes feces to slide down to the enclosed fecal collection tank at the bottom. Some models integrate fecal biochemical processors that decompose feces using microorganisms and build a circulating water system, further reducing water consumption.

Technical Advantages

• Water-saving and environmentally friendly: The water consumption per person is only about 0.04 liters, and the daily power consumption does not exceed 0.2 degrees. The water-saving rate can reach over 99% (after integrating the fecal biochemical processor).
• Odor and splash prevention: The foam layer completely isolates waste from the air, preventing the gathering of mosquitoes and flies and keeping the surrounding environment clean.
• Strong adaptability: It can operate stably in extreme environments ranging from -40°C to 50°C without the need for complex water and electricity facilities, making it suitable for outdoor scenarios such as scenic spots, construction sites, and temporary event venues.
• Economical and practical: It achieves waste isolation and transfer through physical properties, reducing the use of chemical agents and lowering long-term maintenance costs.

Equipment Composition

The core devices include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. They use the U-shaped tube principle to stabilize the amount of foaming agent and generate a long-lasting foam layer in conjunction with compressed air. Some models are equipped with fecal biochemical processors that decompose feces using microorganisms and recycle water resources, forming a closed-loop treatment system.

Application Scenarios

It is widely used in water-scarce areas or places with high environmental protection requirements, such as scenic spots, camping bases, and construction sites. When the fecal collection tank is full, it is pumped and transferred to a treatment site by a dedicated sewage discharge vehicle to avoid secondary pollution.

Market Price

The price of stainless steel foam-sealed squatting toilets ranges from 1140 yuan to 2090 yuan, and the price of foaming agent supplements (20 kg packages) is approximately 4.5 yuan to 160 yuan. The costs are controllable and offer high cost-effectiveness.

This technology combines physical and biological methods to achieve high efficiency, environmental protection, and economy in mobile toilets, representing an innovative solution in the field of outdoor sanitation facilities.
