Chlorine dioxide can destroy the activation enzyme of single cell virus and bacteria attached to the cell membrane, while the enzyme of multicellular organism is on the cell wall. The cell membrane has a good barrier effect on the destructive effect of chlorine dioxide, so chlorine dioxide can be used as A broad spectrum of fungicides to use.
The specific roles and applications of chlorine dioxide are as follows:
The advantage of chlorine dioxide disinfectant compared with other disinfectants is that the cost performance is very high. Because of the non-toxicity of chlorine dioxide mentioned above, chlorine dioxide has been widely used in various occasions, especially for disinfection of tap water. The original disinfection from the water plant is disinfected with liquid chlorine. The smell is particularly large, which can easily cause nausea and vomiting. It also produces chloroform, which is a carcinogen. At the same time, the storage of liquid chlorine is also easy to cause leakage. The accident caused a major accident, so as a water plant, liquid chlorine has now basically been eliminated.
At present, part of the water plant uses a chlorine dioxide generator to produce chlorine dioxide on site by a mixture of sodium chlorate (NaClO3) and hydrochloric acid (HCL). The disadvantage is that sodium chlorate is a dangerous chemical. It is strictly controlled by the state, and hydrochloric acid, as a highly corrosive solution, is strictly controlled by the state, which brings great inconvenience to the use of chlorine dioxide.
At present, the most convenient method for the application of chlorine dioxide is the use of chlorine dioxide disinfectant. Now, the form of chlorine dioxide is mainly 2% liquid chlorine dioxide, 6%-10% foam. Teng tablets, 6%-10% powder, 20%-50% powder.
For the waterworks, more than 45% of the powder is generally used; 2% of the liquid chlorine dioxide is generally used in the disinfection of bottled water; 10% of the powder is widely used in the aquaculture field, which can make the survival rate of the fish and shrimp culture Increase by more than 60%, greatly reducing the risk of breeding;
As a strong oxidant, chlorine dioxide has no triple reaction (teratogenic, carcinogenic, mutagenic) and has become a broad-spectrum disinfectant.
