Research and Development of Mobile Public Toilets in Liaoyuan

Admin October 10, 2026

The research and development of mobile public toilets in Liaoyuan focus on technology integration, modular design, environmental innovation, and scenario adaptability optimization, forming an efficient and sustainable solution.

Technical Modules and Operating Principles

The core functions of mobile public toilets rely on the coordinated operation of three major technical modules:

  1. Waste Treatment System: Solid excreta are treated through biological degradation (e.g., adding specific bacteria to accelerate organic matter decomposition) or physicochemical methods (e.g., high-temperature oxidation, chemical disinfection), reducing odors and the risk of pathogen transmission.
  2. Resource Recycling Unit: Urine is converted into reusable clean water for flushing or irrigation through multi-stage treatment processes such as sedimentation, filtration, and disinfection; some models are equipped with rainwater collection devices to further reduce water consumption.
  3. Environmental Control Components: Integrated ventilation systems (e.g., forced exhaust and negative pressure design) and temperature regulation devices (e.g., electric heating or phase change material insulation) ensure fresh internal air and appropriate temperatures, enhancing user comfort.

Modular Design and Material Innovation

The main structure adopts modular assembly technology for easy and rapid disassembly and transportation, adapting to scenarios such as temporary events and post-disaster reconstruction. The outer frame is made of corrosion-resistant alloys or polymer composites, balancing lightweight and durability; internal partitions partially use recycled plastics, forming a closed-loop material flow of 'manufacturing-use-recycling'. The functional area layout is optimized based on ergonomics, divided into independent usage spaces, equipment compartments (including treatment systems), and storage units, improving space utilization.

Environmental Protection and Resource Recycling Technologies

  1. Waterless Flushing Technology: The biological agent decomposition waste mode can save thousands of liters of clean water annually, suitable for water-scarce areas.
  2. Solar Power Supply: Photovoltaic panels supply power to lighting and ventilation systems, reducing reliance on traditional power grids and lowering operational carbon emissions.
  3. Micro Water Circulation: High-end models convert precipitation into flushing water through rainwater collection, filtration, and disinfection, achieving water self-sufficiency.

Functional Segmentation and Scenario Adaptation

Specialized models are developed for different usage scenarios:

  • Barrier-Free Design: Equipped with ramps, handrails, and low-position toilets to meet the needs of disabled individuals and the elderly.
  • Mother-and-Baby Friendly: Integrated with nursing stations, child safety seats, and small toilets to enhance convenience for families.
  • Cold Region Adaptation: Adopts double-layer insulation structures, freeze-proof piping, and low-temperature startup technologies to ensure normal operation in environments as cold as -30°C.

Research and Production Entity

Cangzhou Hengtai Sanitation Equipment Co., Ltd. is the primary research and development enterprise in the Liaoyuan region. Its products cover vehicle-mounted, mobile, solar, and eco-friendly toilets, extending to supporting facilities such as sanitation worker rest areas and mobile kiosks, forming a diversified product line.
