Gejiu Mobile Toilet Renovation

The core measure of Gejiu's mobile toilet renovation is the introduction of an 'ultrasonic atomization deodorization system,' supplemented by automatic air fresheners, to achieve intelligent and odor-free upgrades to public toilet environments.

Technical Principles and Functions of the Ultrasonic Atomization Deodorization System

This system uses high-frequency vibration technology as its core to convert natural plant extracts into micron-sized water mist (approximately 1-10 microns in diameter). The mist actively diffuses and undergoes physical adsorption and chemical degradation reactions with odor molecules in the air, such as ammonia and hydrogen sulfide. Simultaneously, it utilizes the surface tension of the water mist to carry away bacteria and dust, achieving a triple effect of 'deodorization, sterilization, and dust reduction.' The system's backend supports fragrance switching (e.g., jasmine, lotus, rose), using the volatile components of different plant extracts to mask residual odors, transforming public toilet environments from traditional 'embarrassment zones' into 'relaxation zones.'

Intelligent Management and Operational Convenience

The system integrates an IoT module, allowing sanitation workers to remotely control it via a mobile app:

• Mist volume adjustment: Dynamically adjusts water mist concentration based on public toilet foot traffic to avoid resource waste;
• Timed operation: Sets low-frequency operation during off-peak hours to reduce energy consumption;
• Environmental monitoring: Displays real-time PM2.5 values and automatically activates an enhanced mode when levels exceed standards.
  Additionally, the system features a wall-mounted design (dimensions 50 cm × 30 cm), resembling a mini air conditioner, and can be installed in corners without occupying space. Maintenance only requires periodic replenishment of plant extracts, making operation simple.

Coverage and Collaborative Measures

Currently, 32 public toilets in Gejiu's urban area have been renovated, with plans to cover all 68 by the end of the year. To further ensure air quality, 120 automatic air fresheners operate simultaneously, continuously releasing trace amounts of fragrance 24/7 to maintain a 'safe line for floral fragrance concentration.' This combined strategy eliminates odors at the source through the ultrasonic system while using air fresheners as a supplementary measure, forming a dual safeguard of 'active treatment + passive masking' to ensure long-term compliance of public toilet environments.

Renovation Significance and Promotional Value

This renovation project addresses the pain points of traditional public toilets, such as 'heavy odors and crude management,' through technological innovation, enhancing citizens' restroom experiences. It also provides a replicable model for smart city sanitation management. Its modular design and low-cost operation and maintenance model (with renovation costs per public toilet around several thousand yuan) hold high promotional value, especially for upgrading old urban areas or mobile toilets.
