Chlorine (Cl2) is a colorless, irritating gas with strong corrosivity and toxicity. In practical application, chlorine supplement and disinfectant are widely used to treat water containing chloride pollutants, as well as in water treatment and disinfection. This article will introduce the practical application and potential risks of chlorine gas supplement and elimination agent.
1、 The practical application of chlorine gas supplement and elimination agent:
Equipment selection: select appropriate equipment to deal with chlorine supplement and disinfectant. In general, the use of sealed systems and corrosion-resistant materials can effectively reduce potential hazards. The equipment includes solution storage tank, solution supply device, injection device, reaction vessel, etc.
Solution preparation: prepare a disinfectant solution of appropriate concentration. Chlorine supplement and disinfectant are generally supplied in liquid form, which needs to be prepared according to specific application requirements and relevant formulas.
Injection device: inject the disinfectant solution into the water containing chloride pollutants through the injection device. Adjust the injection volume and speed of the disinfectant solution according to the characteristics and pollution degree of the water body.
Stirring and mixing: Stir and mix the water body to ensure full contact reaction between the disinfectant and chloride. This can be achieved by mixing equipment, water flow or other mechanical methods.
Reaction time: determine the reaction time between the disinfectant and chloride according to the actual situation. Generally speaking, higher temperature and pH value can speed up the reaction. In practical application, appropriately extending the reaction time may improve the effect of supplementation and elimination.
Water treatment: after treatment, further treatment and treatment process selection shall be carried out for the water body as required to remove the residue of disinfectant and meet the discharge standard.
2、 Potential risks of chlorine supplements:
Toxicity: chlorine is highly toxic. Inhalation of excessive chlorine may cause asphyxia and poisoning. In actual operation, the chlorine concentration must be strictly controlled to ensure the safety of operators.
Corrosivity: Chlorine is highly corrosive. If it is used incorrectly or leaked, it may lead to corrosion of equipment and containers. Therefore, measures shall be taken to ensure the corrosion resistance of equipment during operation.
Explosive: chlorine may cause explosion when contacting with combustible substances. Therefore, attention must be paid to the isolation and storage of flammable materials during operation.
Chlorate formation: Chlorine reacts with water to form chlorate, and high concentration of chlorate will have a negative impact on the environment. Therefore, attention should be paid to controlling the acid-base balance and preventing the formation of excessive chlorate when using chlorine gas disinfectant.
Public health risk: if the supplement is not fully reacted or improperly handled, it may pose a threat to the surrounding environment and public health after discharge. Therefore, in practical application, the treatment process must be reasonably designed to ensure the effective treatment and discharge of the disinfectant supplement up to the standard.
To sum up, chlorine supplement and disinfectant can be realized by selecting appropriate equipment, solution preparation, injection device, mixing and other operations in practical application. However, potential risks include toxicity, corrosiveness, explosiveness, chlorate formation and public health risks of chlorine. In order to reduce potential risks, operating conditions must be strictly controlled, necessary safety measures must be taken, and treatment processes must be reasonably designed to ensure safety and environmental protection.
