Mobile Toilets for Urban Renovation

Mobile toilets used in urban renovation are facilities that can be moved as a whole, providing public toilet services with advantages such as mobility, modularity, and ease of transportation.

I. Basic Components Mobile toilets typically consist of core components such as fecal sewage storage tanks (or disposal units), flooring, sanitary fixtures, walls, washing equipment, water tanks, roofs, and mobility devices. Among these, the fecal treatment system is crucial and can be classified into water-flush, waterless suction, recirculating water-flush, and dry-packing types based on technological differences. For example, water-flush types require matching water tanks and sewage pipes, while waterless types rely on sealed storage tanks for periodic cleaning. Recirculating water-flush types achieve water reuse through biodegradation technology, and dry-packing types directly collect feces and replace packaging bags.

II. Classification Methods

1. Structural Form: Divided into single-unit structures (independent units) and composite structures (multi-unit combinations). The former is suitable for space-constrained scenarios, while the latter can be expanded into large public toilets.
2. Mobility Method: Includes lifting and handling types (requiring lifting equipment) and powered towing types (with self-contained power or towable by vehicles). The former offers high flexibility, while the latter is suitable for long-distance transportation.
3. Sewage Treatment: Water-flush types rely on water sources and sewage systems, waterless types are cleaned by suction trucks, recirculating water types use microbial decomposition to reduce water usage, and dry-packing types are completely water-free and pollution-free.

III. Application Scenarios and Advantages Mobile toilets can be quickly deployed at construction sites, scenic parks, temporary event venues, etc., especially meeting the transitional needs after the demolition of traditional toilets during urban renovation. Their core advantages include:

• Flexibility: They can be relocated according to project progress or crowd flow, avoiding the site selection limitations of fixed toilets.
• Environmental Friendliness: Dry-packing and recirculating water-flush types significantly reduce water consumption, meeting green construction requirements.
• Economy: Compared to traditional toilets, mobile toilets do not require underground pipeline construction, and long-term use can reduce costs through repeated disassembly and assembly.

IV. Typical Case Mobile toilets produced by Henan Hemai Industrial Co., Ltd. are made of color steel plates or metal carved plates, with specifications including 1.3×1.3×2.35 meters and 1.1×1.1×2.35 meters. They are adaptable to extreme environments ranging from -35℃ to 100℃, support 220V power supply, and offer customized designs. These toilets have been widely used in construction projects in cold northern regions and high-temperature scenic spots in the south.
