Mobile Toilets During the Epidemic

During the epidemic, mobile toilets effectively reduced the risk of cross-infection and ensured public health safety by strengthening disinfection and epidemic prevention functions, enhancing emergency support capabilities, and through technological innovation.

I. Strengthening Disinfection and Epidemic Prevention Functions

1. Automated Cleaning and Disinfection Technology: The “unmanned toilet” developed by Hangzhou Zhide Pusi Technology Co., Ltd. employs a toilet rotation replacement and integrated floor cleaning push-plate technology, which can complete the disinfection of the toilet and floor within 6-10 minutes after the user leaves. Simultaneously, ozone is released from the top to comprehensively disinfect the space, reducing the risk of manual contact.
2. Negative Pressure Air Treatment System: The mobile toilets from Lianjia Jisheng (Suzhou) Environmental Technology Co., Ltd. transport air through low-level air intakes to a top sterilization system, utilizing positive oxygen ions to destroy bacterial structures and negative oxygen ions to freshen the air. The treated gas is discharged harmlessly, preventing aerosol transmission.
3. Foam Sealing and Bacteriostatic Technology: The active agent foam from Jiangsu Feimu Biotechnology Co., Ltd. covers the surface of excreta, inhibiting the proliferation of bacteria in the water through physical “suffocation” while reducing the amount of flushing water used and lowering the possibility of virus spread through aerosols.
4. Multi-modal Disinfection Integration: The epidemic prevention public toilets developed by the academician team led by Meng Jianmin in Shenzhen combine technologies such as nano-mist disinfection, photocatalytic antibacterial panels, and negative pressure fresh air. After each use, the internal space is automatically disinfected 360° without dead angles, forming multiple protective barriers.

II. Emergency Support and Logistical Support

1. Applications in Fangcang Shelters and Isolation Points: Shanghai Pudong Sanxing Environmental Sanitation Co., Ltd. deployed more than 500 mobile toilet units during the epidemic. Through leak-proof designs, vacuum suction technology, and zoned management (including barrier-free access and母婴台面 (mother-and-baby countertops)), they met the diverse needs of high-density populations and removed over 1,600 tons of feces, blocking fecal-oral transmission routes.
2. Rapid Deployment Capability: The epidemic prevention mobile public toilets in Shenzhen adopt a modular design, allowing installation to be completed within 3 hours. They are suitable for scenarios such as vaccine接种点 (vaccination sites) and temporary testing stations, addressing the issue of long construction periods for traditional public toilets.

III. Technical Details and Patent Support

The epidemic prevention public toilets in Shenzhen have applied for 34 patents, covering core technologies such as contactless door opening, sensor faucets, and enclosed disinfection systems. Among them, the sterilization system of the negative pressure toilets generates positive oxygen ions through ion tubes, which combine with odor molecules to form odorless compounds, achieving efficient sterilization and odor control. These innovative designs significantly reduce the risk of infection for cleaning staff, reflecting the deep integration of technology and public health needs.
