Zhengzhou Mobile Toilet Disinfection

The disinfection methods for mobile toilets in Zhengzhou mainly include physical disinfection methods, chemical disinfection methods, and safety protection measures, as detailed below:

Physical Disinfection Methods

Physical disinfection methods destroy the structure of pathogens through physical means, achieving a disinfection effect without chemical residues.

• Ultraviolet Disinfection: Use ultraviolet disinfection equipment to irradiate the treated feces and equipment surfaces for a duration of no less than 30 minutes. Ultraviolet light can penetrate the cell membranes of microorganisms, damage their DNA structure, and effectively kill bacteria and viruses.
• High-Temperature Steam Disinfection: When conditions permit, use high-temperature steam to treat feces, ensuring that the temperature reaches above 80℃ and is maintained for more than 30 minutes. High temperatures can denature proteins, thoroughly killing pathogens, and are suitable for disinfecting heat-resistant equipment.

Chemical Disinfection Methods

Chemical disinfection methods destroy the structure of pathogens through the oxidation and chlorination effects of chemical agents, requiring the control of concentration and exposure time based on the characteristics of the agents.

• Chlorine-Based Disinfectants:
  • Bleaching Powder: Dilute at a ratio of 1:100 - 1:200 and spray, with an exposure time of 30 minutes to 1 hour. The hypochlorite in bleaching powder can release active chlorine, damaging the enzyme systems of microorganisms.
  • Sodium Hypochlorite: Control the available chlorine content at 500 - 1000mg/l, and maintain for 30 minutes after spraying. Sodium hypochlorite kills pathogens through chlorination and is suitable for disinfecting equipment surfaces.
• Peracetic Acid: Use a 0.5% - 1% concentration solution for spraying, strictly wearing safety protection equipment (such as goggles and gloves), and rinse with water after application. Peracetic acid has strong oxidizing properties and can rapidly decompose the cell membranes of microorganisms.
• Chlorine Dioxide: Use 5 - 10mg per cubic meter of water, dissolve and spray for 30 minutes. Chlorine dioxide destroys the proteins of pathogens through oxidation and is suitable for disinfecting air and equipment.

Safety Protection Measures

During the disinfection process, protective measures should be taken to avoid exposing personnel to harmful substances.

• Personal Protection: Staff should wear protective clothing, gloves, masks, and goggles to avoid direct contact with contaminants and prevent skin or respiratory damage.
• Ventilation: After operation, maintain environmental ventilation for more than 30 minutes to expel residual disinfectant gases or pathogens through air circulation, reducing the risk of secondary pollution.

In addition, some mobile toilet rental companies in Zhengzhou offer integrated cleaning, maintenance, and disinfection services, allowing users to choose professional teams for operation according to their needs.
