Licang Mobile Toilet

“Licang Mobile Toilet” is not a universally standardized term. It is presumed to refer to a modular mobile toilet equipped with an independent fecal storage tank (septic tank), with its core design centered around an “independent sewage system” and “mobility”.

I. Basic Components and Structural Types

Mobile toilets typically consist of modules such as fecal and sewage storage tanks (or disposal units), flooring, sanitary fixtures, walls, washing facilities, water tanks, roofs, and mobility devices. Based on structural form, they can be classified into monolithic structures (single independent units) and composite structures (combinations of multiple modules). In terms of mobility, they are divided into lifting/handling types (requiring mechanical assistance for movement), powered/trailer types (equipped with their own power or towable for travel), and by sewage treatment method, into flush types (requiring a water connection), non-flush suction types (relying on vacuum suction for waste removal), recirculating flush types (where sewage is purified and reused), and dry-pack types (where feces are packed in biodegradable bags without the need for flushing).

II. Core Mechanisms and Key Design Features

Its core mechanisms are modular integration and an independent sewage system:

• Modularity: Each functional unit (such as the fecal tank, fixtures, and water tank) is independently designed, facilitating rapid assembly, disassembly, and transportation, making it suitable for temporary events, disaster relief, and other scenarios.
• Independent sewage: The fecal storage tank (septic tank) employs a sealed design to prevent odor leakage and sewage overflow. Some models are equipped with degradation agents or solid-liquid separation devices to extend the cleaning cycle.

Key design considerations include:

• Tank structure: It must balance strength and lightweight construction, with commonly used materials being stainless steel (corrosion-resistant, long-lasting, suitable for high-frequency use scenarios) and color-coated steel plates (low cost, easy to process, suitable for short-term or low-frequency use).
• Septic tank capacity: Determined based on the number of users and cleaning cycle. For example, a toilet serving 100 people per day typically requires a fecal storage tank capacity of ≥1 cubic meter.

III. Application Scenarios and Advantages

Such toilets are suitable for areas without fixed sewage networks, such as outdoor music festivals, construction sites, tourist attractions, and emergency disaster relief. Their advantages include:

• Flexibility: They can be quickly deployed and relocated, reducing reliance on fixed facilities.
• Environmental friendliness: Dry-pack or recirculating flush models reduce water consumption, and some models support the resource utilization of feces (such as composting).
• Cost-effectiveness: Compared to traditional toilets, they have lower construction costs and can be reused, resulting in lower long-term operating costs.
