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 to improve product quality by refining or distilling the product, bromine-containing wastes will inevitably be generated in the production.

[0003] If bromine-containing waste is discarded or improperly disposed of, the bromine in it may seep into the soil. Bromine will accumulate in the soil and affect the physical, chemical and biological properties of the soil. For example, high concentrations of bromine may change the pH of the soil, destroy the soil structure, reduce soil fertility, and thus affect the growth and development of plants. Long-term soil pollution may also lead to an imbalance in the soil ecosystem, affecting the survival and activities of microorganisms, earthworms and other organisms in the soil, and thus affecting the function of the entire ecosystem. Bromine in bromine-containing waste may enter the water body through rainwater erosion, surface runoff and other channels, causing water pollution. Bromine may exist in different forms in water, such as bromide ions and bromine elements. High concentrations of bromine can have toxic effects on aquatic organisms and destroy 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, and has potential hazards to human health and the environment.

[0004] However, it is currently inconvenient to quickly and efficiently treat bromine-containing wastes, and the treatment efficiency of bromine-containing wastes 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
