Water Quality Disinfection and Sterilization Treatment

Disinfection of hospital wastewater and swimming pool water is a crucial task, and sodium hypochlorite generators are commonly used in water treatment. The reason sodium hypochlorite generators are effective in disinfection is due to the sodium hypochlorite solution they produce. This solution acts as a strong oxidizing agent with powerful antimicrobial properties, capable of rapidly killing various pathogenic bacteria and viruses.

The system utilizes an electrolytic cell to electrolyze sodium chloride and/or hydrochloric acid solutions, producing an acidic aqueous solution (pH < 6.5) with hypochlorous acid as the main antimicrobial component. The process in the micro-acidic electrolyzed water generator is an electrochemical reaction. Under the influence of the cell voltage, chlorine gas is generated at the anode, and reacts with hydroxide ions at the cathode to form a hypochlorous acid solution, with sodium ions not participating in the reaction.

Due to the scarcity of water resources, urban domestic and industrial wastewater undergo recycling after treatment, which necessitates higher standards for wastewater treatment. Ozone disinfection is employed for advanced treatment to remove impurities from wastewater, ensuring it meets reuse standards. Many cities now use large-scale ozone generators in wastewater treatment systems to achieve decolorization, deodorization, and disinfection.

The principle of UV disinfection involves using high-energy ultraviolet (UV) photons to damage the DNA and RNA structures of various viruses, bacteria, and pathogens in water. This disruption impairs their ability to produce proteins and reproduce, effectively killing them. UV disinfection is a physical process where UV light directly acts on the genetic material of microorganisms, and it can inactivate known pathogenic microorganisms within 0.1 to 2 seconds.
