Vehicle-mounted Mobile Toilet Disinfection Spray

Currently, there is no standardized disinfection spray product specifically designed for vehicle-mounted mobile toilets, but disinfection needs can be met through a combination of equipment. The following are specific solutions and analyses:

1. Vehicle-mounted Ozone Disinfection Equipment: Core Tool for Nighttime Deep Sterilization
Vehicle-mounted ozone disinfectors (such as a model priced at ¥129) achieve 360-degree sterilization without dead angles by releasing ozone. Their oxidizing properties can decompose bacterial cell membranes and destroy odor molecules. The advantages include no need for manual operation and the ability to cover dead spots in enclosed spaces. The limitations are that the ozone concentration must be controlled below 0.1ppm (national standard GB/T 18883-2002), and ventilation for more than 30 minutes is required after disinfection to avoid residual irritation. It is recommended to activate the equipment at night when no one is using it, and cooperate with the ventilation system of the mobile toilet to accelerate ozone decomposition.

2. Portable Atomizing Disinfection Gun: Supplementary Solution for Daily Cleaning
The handheld atomizing disinfection gun (such as the wireless K5 model priced at ¥38.0) sprays alcohol or chlorine-containing disinfectant into 1-10μm particles through high-pressure atomization, covering high-frequency contact areas such as the inner walls of the toilet bowl and door handles. Operating Points:

• Choose 75% medical alcohol or a disinfectant containing 500mg/L of available chlorine;
• Keep the surface wet for 3-5 minutes after spraying to achieve virus inactivation (according to the "Prevention and Control Plan for COVID-19");
• Use it 2-3 times a day, focusing on areas in contact with excreta.
  Note: Avoid using alcohol-based disinfectants in environments with open flames or high temperatures.

3. Reasons for Excluding Inapplicable Solutions

• Vehicle-mounted Long-range Sprayer: Equipment with a medicine tank capacity of ≥2 tons and dimensions of 4.6×2.2m clearly exceeds the space requirements of mobile toilets, and a flow rate of 16-24L/min poses a risk of liquid overflow.
• Ordinary Deodorizing Spray: For example, Aienbei deodorant (¥7.8) only contains surfactants and fragrances and cannot kill intestinal pathogens (such as Escherichia coli and norovirus), failing to meet the standard of ≤10CFU/cm² for bacterial count in toilets specified in the "Hygienic Indicators and Limit Values for Public Places" (GB 37488-2019).

4. Recommendations for Combined Use
Daily Maintenance: After each use, spray disinfectant with a portable atomizing gun, focusing on the toilet bowl and handrails;
Deep Cleaning: Activate the ozone disinfector twice a week at night and ventilate after disinfection;
Emergency Response: When vomit or other contaminants are found, immediately wipe with a chlorine-containing disinfectant and increase the frequency of ozone disinfection.
This solution can achieve a bacterial inactivation rate of over 90% while controlling costs within 200 yuan (ozone equipment + disinfection gun combination).
