Description

Technical Field

[0001] The present invention relates to the technical field of bromine-containing waste treatment, and in particular to a bromine-containing waste treatment method and treatment equipment. Background Art

[0002] Bromination reaction is a commonly used reaction in industrial production. Since most bromination reactions have polybromination side reactions, and some processes that improve product quality by refining or distilling the products will inevitably produce bromine-containing wastes in the production process.

[0003] If bromine-containing waste is discarded or improperly disposed of, the bromine in it may seep into the soil. Bromine accumulates in the soil, affecting its physical, chemical, and biological properties. For example, high concentrations of bromine can alter soil pH, disrupt soil structure, and reduce soil fertility, thereby impacting plant growth and development. Long-term soil contamination can also disrupt the balance of the soil ecosystem, affecting the survival and activity of microorganisms, earthworms, and other organisms in the soil, ultimately affecting the functioning of the entire ecosystem. Bromine from bromine-containing waste can enter water bodies through rainwater washout and surface runoff, causing water pollution. Bromine can exist in water in various forms, such as bromide ions and elemental bromine. High concentrations of bromine can be toxic to aquatic organisms and disrupt the balance of aquatic ecosystems. Under certain conditions, some bromine-containing wastes may release bromine vapor into the atmosphere, causing air pollution. Bromine vapor is irritating and toxic, posing potential hazards to human health and the environment.

[0004] However, it is currently inconvenient to quickly and efficiently treat bromine-containing waste, and the treatment efficiency of bromine-containing waste is low. Therefore, it is necessary to design a bromine-containing waste treatment method and treatment equipment to solve the above problems. Summary of the Invention
