1. The oxidation of chlorine dioxide is selectively reacted with inorganic and organic substances.
For example, it can react with inorganic substances such as oxides, sulfides, iron and manganese, and organic matter such as phenols, chlorophenols, thiols, secondary amines, and tertiary amines; but not
It reacts with some chlorine-consuming substances such as nitrogen-containing organic matter, and disinfects without producing chlorophenol odor and chlorohydrogens such as trihalomethane, so it is especially suitable for wastewater containing more phenols or organic matter dirt.
2, chlorine dioxide sterilization effect is better than chlorine, with the increase of pH, this advantage is more obvious.
Relevant studies have shown that at low concentrations, chlorine dioxide is more effective than chlorine, because low concentrations of chlorine dioxide dioxide diffuse faster in water than chlorine. CodJun also found that it has a good removal effect on algae, isooxy bacteria, iron bacteria, sulfate reduction bacteria, etc. in water treatment systems in pools, filtration equipment and water pipes.
3. The bactericidal ability of chlorine dioxide is less affected by pH value, and has a strong oxidation capacity in a wide pH range, and the oxidation capacity is 2 times that of free chlorine.
Chlorine dioxide can oxidize manganese, iron and other reducing substances faster, while removing the smell caused by chlorophenols and algae in water, it also has a strong bleaching effect, which can remove the color of wastewater. Moreover, the temperature increases, and the bactericidal effect of chlorine dioxide is enhanced.
4. Chlorine dioxide is consumed without reacting with compounds such as ammonia nitrogen in water.
Under the same effective chlorine dosage, a high residual chlorine concentration can be maintained and a better disinfection and sterilization effect can be achieved.
