Tangshan Foam-Type Mobile Toilet

The Tangshan foam-type mobile toilet is a type of mobile toilet that uses a special foaming agent to convert excreta into tiny bubbles, achieving isolation between waste and air. It has the advantages of water conservation, environmental protection, and effective odor control.

Operating Principle: Its core operation is a closed circulation system that relies on a foaming agent solution. When in use, a small amount of specialized foaming concentrate and a small volume of water are mixed under the action of an air pump, generating a large amount of viscous and fine foam inside the toilet fixture. This foam can completely cover the excreta outlet, forming a physical seal that effectively blocks the upward escape of odors. It also wraps around the excreta, isolating it from the air, slowing down the decomposition process of organic matter, and significantly reducing reliance on large volumes of cleaning water and frequent suctioning.

Advantages and Features:

• Water Conservation and Environmental Protection: Compared to traditional water-flush mobile toilets, which consume a relatively large amount of water per use, foam-sealing technology mainly relies on a small amount of water and foaming liquid, greatly reducing water consumption and aligning with water conservation concepts.
• Effective Odor Control: In crowded temporary event venues or during high-temperature summer conditions, the sealing effect of the foam can quickly and continuously suppress the spread of odors, improving local environmental hygiene.
• High Adaptability: Mobile toilets can be placed in various locations, some of which may lack stable water supply or drainage conditions. The foam-sealing system has relatively low dependence on infrastructure, making installation and operation relatively flexible.
• Easy Post-Processing: The wrapping of waste by the foam is, to a certain extent, beneficial for subsequent cleaning and centralized treatment, reducing the risk of secondary pollution during transportation.

Application Scenarios: It has a wide range of applications in the Tangshan area. For example, during the 2026 Spring Festival, the Tangshan Nanhu·Kailuan Tourist Scenic Area deployed more than 50 intelligent mobile environmental toilets using foam-type environmental protection technology. These toilets feature an integrated design of the waste tank and the main toilet body, enabling harmless treatment without the need for external water and electricity connections. They truly achieve "plug-and-play, easy removal and relocation", with environmental protection performance meeting national standards.
