Chongqing Mobile Toilet Configuration
The configuration of mobile toilets in Chongqing varies according to type and demand, covering multiple aspects such as structural design, water supply and sewage disposal, ventilation and purification, as detailed below:
1. Structural Design and Materials
The main structure of mobile toilets often employs steel plates, stainless steel, or high-strength plastics. The outer shell undergoes anti-rust treatment and high-strength spraying for easy cleaning and maintenance. For simple mobile restrooms, the exterior/interior walls use 5-centimeter-thick color-steel sandwich panels, with galvanized steel frames for the structural skeleton. The floor adopts galvanized anti-slip patterned plates, while the columns and trim are made of aluminum alloy, balancing durability and lightweight requirements.
2. Water Source Capacity and Water Supply System
Water tank capacities typically range from 200 to 500 liters, equipped with filtration devices to ensure water quality meets usage standards. Some high-end models support recirculating water systems, achieving water reuse through multi-stage filtration to reduce water consumption.
3. Sewage Disposal and Treatment
Sewage tank capacities range from 300 to 1000 liters, with sewage system designs emphasizing airtightness to prevent odor leakage. Simple mobile restrooms offer two sewage disposal modes: direct discharge requires connection to a septic tank or sewage pipeline, while fecal tank models use independent containers to store waste for periodic cleaning. High-end models are equipped with simple sewage treatment devices for preliminary purification.
4. Ventilation and Air Purification
Equipped with exhaust fans and air purifiers, the size and airflow of exhaust fans are adjusted according to the toilet volume and usage frequency. Air purification devices use HEPA filters or activated carbon materials to effectively adsorb odors and harmful gases. Simple mobile restrooms come standard with exhaust fans to meet basic ventilation needs.
5. Internal Space Layout and Facilities
Internal facilities include wet-dry separation designs, handwashing stations, mirrors, energy-efficient lighting fixtures, and waste bins. Simple mobile restrooms come standard with handwashing basins, ceramic squat toilets, switches, ball locks, light bulbs, and restroom signs. Some models support customization, such as adding handrails or child-specific facilities.
6. Power Supply System
Power sources include storage batteries or vehicle-mounted generators, with battery capacities typically ranging from 50 to 200 ampere-hours, supporting the operation of lighting, ventilation, and other equipment for several hours to several days. Some models are equipped with solar panels for green energy supplementation.
7. Safety Measures and Fire Protection Systems
Equipped with fire extinguishers, emergency lights, and evacuation indicators, wiring layouts use flame-retardant materials and reserve maintenance space to prevent short circuits or electrical fire risks. Simple mobile restrooms must comply with national fire safety standards to ensure safe usage.
8. Other Additional Configurations
Some mobile toilets include storage cabinets for hand sanitizer and disinfectants or are equipped with air conditioning and heating devices to adapt to extreme climates. Simple mobile restrooms support customization of overall dimensions and internal facilities to meet the personalized needs of different scenarios.
