Suzhou Mobile Toilet Disinfection

The disinfection work of mobile toilets in Suzhou ensures hygiene and safety through multi-dimensional measures, including safety protection, cleaning and disinfection, physical and chemical disinfection methods, etc..

In terms of safety protection, cleaning staff must strictly implement personal protective requirements during operations. Cleaning staff in ordinary areas need to wear face shields, medical masks, and gloves for operations; cleaning staff in controlled areas need to implement secondary protection and wear full sets of "big white" protective suits; cleaning staff in the surrounding areas of controlled areas and key areas need to wear blue isolation gowns. Through graded protective measures, the risk of infection among cleaning staff is minimized, and operational safety is ensured.

The cleaning and disinfection system strictly adheres to the principle of "one cleaning and one disinfection per customer". In ordinary areas, disinfection is carried out once every 2 hours using a 1000mg/L disinfectant, while in controlled and restricted public toilets, the frequency is increased to once every hour. Comprehensive cleaning is conducted 4 times a day, and deep cleaning is carried out once a week. All cleaning and disinfection records must be posted on the wall to ensure traceable processes and standardized management.

Physical disinfection methods mainly target feces and equipment surfaces. Using ultraviolet disinfection equipment to irradiate treated feces and equipment surfaces for no less than 30 minutes can effectively kill bacteria and viruses; if conditions permit, high-temperature steam can be used to treat feces, ensuring that the temperature reaches above 80℃ and lasts for more than 30 minutes, thoroughly killing pathogens through high temperatures and providing dual protection for disinfection effects.

Chemical disinfection methods are implemented based on the characteristics of different disinfectants:

• Chlorine-containing disinfectants: Bleach is diluted at a ratio of 1:100-1:200 and sprayed, acting for 30 minutes to 1 hour; sodium hypochlorite with an effective chlorine content controlled at 500-1000mg/L is sprayed and maintained for 30 minutes.
• Peracetic acid: A 0.5%-1% concentration solution is used for spraying, requiring enhanced safety protection, and residual is rinsed off with clean water after application.
• Chlorine dioxide: 5-10mg per cubic meter of water is used, dissolved and sprayed for 30 minutes, suitable for water and space disinfection.

Through the above comprehensive measures, Suzhou mobile toilets have established a "protection-cleaning-physical-chemical" quadruple disinfection system, ensuring public health and safety while considering operational efficiency and environmental protection requirements.
