Family Courtyard Mobile Toilet
The family courtyard mobile toilet is a mobile sanitation facility suitable for places such as family courtyards, featuring flexible installation and diverse functions. The following is a popular science introduction from aspects such as composition, materials, classification, and application in rural home settings:
I. Basic Composition
Mobile toilets are typically composed of core components such as fecal sewage storage tanks (or disposal devices), floor slabs, sanitary ware, walls, washing equipment, water tanks, roofs, and mobile devices. Among them, the storage tank is used to collect excrement. Some high-end models are equipped with biodegradation or chemical treatment devices to reduce odors and pollution. The walls and roofs are mostly made of lightweight materials, taking into account both waterproofing and heat insulation performance. The mobile devices, depending on the design, may include wheels, lifting rings, or towing structures for easy transportation or position adjustment.
II. Common Materials
Material selection directly affects the durability and cost of the toilet. Fiberglass reinforced plastic (FRP) has become the mainstream choice for rural home settings due to its corrosion resistance and ease of cleaning. Color-coated steel and light steel are suitable for temporary needs with their advantages of high strength and low cost. Some high-end products use composite materials, such as a combination of FRP and foam sandwich panels, to further enhance thermal insulation performance.
III. Classification Methods
- By structural form: Divided into single-unit structures (independent units) and composite structures (multi-unit combinations), with the latter being common in public places.
- By mobility: Including lifting-type (requiring lifting equipment), handling-type (moved manually or with small machinery), powered-type (with built-in engines), and towing-type (connectable to vehicles for towing).
- By sewage treatment method:
- Flush-type: Relies on water tank supply for cleaning by flushing, requiring regular cleaning of the septic tank.
- Waterless suction-type: Uses a vacuum pump to suction excrement, suitable for water-scarce areas.
- Recirculating flush-type: Recovers flushing water through a filtration system to reduce water consumption.
- Dry-packing type: Uses degradable bags to collect excrement, requiring no water source and being easy to maintain.
IV. Application in Rural Home Settings
In the rural market, brands such as Jinda and Xinyue offer a variety of products with price ranges from 460 yuan to 650 yuan per set, and some support customization. For example, the Jinda FRP integrated septic tank mobile toilet in Hengshui, Hebei, adopts a 2:8 design and integrates a purification tank function, suitable for decentralized sewage treatment. The Xinyue FRP dry toilet septic tank emphasizes portability and is suitable for temporary use on construction sites. Users can choose models according to family population, water conditions, and budget. Customization services can adjust dimensions, colors, or add additional functions such as solar lighting.
