Portable Demountable Mobile Toilet

A portable demountable mobile toilet is a sanitary facility with characteristics of mobility, modularity, ease of transportation, and assembly/disassembly, suitable for various locations such as stations, docks, tourist attractions, and construction sites.

I. Structural Composition Mobile toilets are typically composed of core components including fecal sewage storage tanks (or disposal units), flooring, sanitary fixtures, walls, washing equipment, water tanks, roofs, and mobility devices. Their structural forms can be divided into two categories:

1. Monolithic Structure: Designed as an independent unit, suitable for scenarios with limited space or temporary needs.
2. Composite Structure: Composed of multiple modules that can be combined to expand scale as needed, such as adding toilet stalls or functional areas.

II. Mobility Classification Based on transportation and installation requirements, mobile toilets can be classified into the following types:

1. Lifting and Handling Type: Relies on lifting equipment or manual handling, suitable for short-distance movement or repeated use at fixed locations.
2. Powered and Trailer Type: Equipped with a power system (such as electric drive) or a trailer device, enabling long-distance transportation via vehicle towing for greater flexibility.

III. Sewage Treatment Methods Mobile toilets employ four types of sewage treatment technologies tailored to different environmental conditions:

1. Flush and Non-Flush Suction Type: Flush types rely on water tank supply for flushing, with sewage requiring periodic suction and treatment; non-flush types reduce water usage through vacuum suction or chemical degradation.
2. Recirculating Flush Type: Utilizes a closed water circulation system with filtration and disinfection technologies to purify and reuse sewage, suitable for water-scarce regions.
3. Dry Packing Type: Directly packs feces and solid waste into biodegradable bags without flushing, ideal for remote areas without sewage pipelines or temporary events.

IV. Market Prices and Brands Prices vary significantly based on specifications, materials, and functions:

• Outdoor mobile environmental toilet (demountable restroom) in Chengdu, Sichuan: 2,500 yuan per unit.
• Construction site mobile toilet in Weifang, Shandong: 1,200 yuan per square meter.
• Aluminum alloy mobile toilet by Shanghai Changjiu: 398 yuan per set.
• Guangzhou Kening Environmental Technology offers a wider product range, with plastic mobile toilets starting at 2,000 yuan and custom color-steel toilets reaching up to 76,000 yuan, covering construction sites, outdoor events, parks, and other scenarios.

Users can select appropriate types based on usage scenarios, budget, and environmental requirements. For example, construction sites may prioritize dry packing types to reduce costs, while tourist attractions are better suited for recirculating flush types to enhance user experience.
