And long-term cooperation with multiple scientific research and design units across the country. We have accumulated rich experience in the design, manufacturing, installation, and commissioning of environmental protection equipment.

1、 Overview

Due to the on-site use of chlorine dioxide, even if there is a leak (in fact, using a high-quality generator will never cause a leak), it will not cause harm to nearby residents and operators. In addition, the activity of chlorine dioxide in water can be maintained for at least 48 hours, and its effective period is longer than chlorine. The use of chlorine dioxide in water distribution networks not only ensures the inhibition of bacterial regrowth, but also kills algae (even surviving algae will lose their reproductive ability). It can also effectively control the odor produced by algae and rotten vegetables, and after disinfection with chlorine dioxide, it will not be as effective as using chlorine dioxideCL₂Chlorine based disinfectants such as sodium hypochlorite react with organic matter in water to produce carcinogens such as trihalomethanes, which are highly favored by the water treatment industry. It can be seen that using chlorine dioxide to disinfect tap water is safe, convenient, economical, and environmentally friendly.

Chlorine dioxide is currently the latest generation of broad-spectrum fungicides, oxidants, and bleaching agents. Thousands of water plants around the world have already used chlorine dioxide for disinfection and treatment of drinking water and wastewater. With the deterioration of water quality caused by pollution of tap water, traditional disinfection processes will no longer be accepted in China's water supply industry. The application of chlorine dioxide in drinking water is developing rapidly.

In 1834, Watt and Burgess discovered the bleaching property of this compound. At the beginning of this century, it was discovered that chlorine dioxide dissolved in dilute acetic acid solution could be used to bleach pulp. In 1940, Matison Alkali Company in the United States achieved industrial production of chlorine dioxide and began its widespread industrial application. In 1944, the Niagara Falls Water Plant in the United States successfully used chlorine dioxide to control the odor and odor caused by algae growth and phenol pollution in water. This demonstrated the significant effectiveness of chlorine dioxide in disinfecting drinking water, especially in treating raw water containing phenols and odors. Subsequently, in the developed West, chlorine dioxide was rapidly promoted in the treatment of drinking water. As early as 1950, Switzerland used chlorine dioxide to disinfect and deodorize phenol containing groundwater; Later, the Zurich water plant extensively used chlorine dioxide for disinfection; In 1979, the Evansville Water Plant in Indiana, USA, used chlorine dioxide as a control for THM_SEffective methods. At present, more than 2000 developed water companies in the world have adopted chlorine dioxide. The application of chlorine dioxide in European and American water plants has shown that replacing chlorine with chlorine can effectively reduce the production of trihalomethanes, especially in lakes with severe algal growth. Chlorine dioxide can effectively reduce the odor of effluent.

The properties of chlorine dioxide

Depending on the concentration, chlorine dioxide is a yellow green to orange gas that has the properties ofCL₂A similar pungent odor with a boiling point of 11 ℃. When the volume concentration in air exceeds 10%, it becomes explosive. However, chlorine dioxide is very stable in aqueous solutions. Unlike chlorine, it does not react with water or undergo acidification in water. Chlorine dioxide is an oxidizing agent, not a chlorinating agent, and its oxidizing ability is 2.5 times that of chlorine. Chlorine dioxide has strong adsorption and penetration ability on cell walls, which can effectively oxidize enzymes containing thiol groups in cells and rapidly inhibit the synthesis of microbial proteins, thereby destroying microorganisms. Chlorine dioxide not only has a killing effect on general bacteria, but also has a good killing effect on buds, viruses, algae, iron bacteria, sulfate reducing bacteria, and fungi. Due to its sensitivity to pressure, chlorine dioxide cannot be shipped or stored for a long time, and usually needs to be used on-site.

The advantages of chlorine dioxide in disinfecting and sterilizing drinking water

1) Sterilization performance

Chlorine dioxide not only has good disinfection and sterilization effects on Escherichia coli, poliovirus, hepatitis virus, and Helicobacter pylori, but also has a better effect than free chlorine. Unlike chlorine, the bactericidal activity of chlorine dioxide is relatively stable over a wide pH range. When the pH is 6.5, the killing rates of 0.25mg/L chlorine dioxide and chlorine on Escherichia coli in one minute are similar; When the pH is 8.5, chlorine dioxide can maintain the same killing efficiencyCL₂It takes 5 times the time, so chlorine dioxide is undoubtedly a suitable disinfectant for high pH and lime softened water. Chlorine dioxide can also effectively kill other infectious bacteria, such as Staphylococcus and Salmonella. When dealing with poliovirus and bacteriophages, the survival rate produced by a dose of 2mg/L chlorine dioxide is much lower than that produced by a dose of 10mg/L.

2) Regarding THM_SThe Control

THM_STotal trihalomethanes are suspected to be carcinogens, while chlorine dioxide can prevent the formation of THMs. Unlike chlorine, chlorine dioxide undergoes an oxidation reaction with THMs precursors such as humic substances and humic acid, and does not form chlorinated organic compounds THMs_sUsually, chlorine dioxide has an effect on THM_sControl is replacing pre oxidation.

3) Algae removal

Chlorine dioxide has a lethal effect on various algae. It not only effectively kills algae, but also causes even surviving algae to lose their reproductive ability. In addition, chlorine dioxide can effectively control the odor produced by algae and rotten vegetables, and can also control actinomycetes that harm organisms and produce odors
