Description

Technical Field

[0001] The invention relates to the technical field related to phosphorus-based flame retardant processing equipment, and in particular to a wastewater treatment device used for phosphorus-based flame retardant processing. Background Art

[0002] As synthetic materials are increasingly used in people's daily lives and national economic construction, the flame retardant treatment of their polymers has attracted more and more attention. Although halogen flame retardants have unparalleled high efficiency compared to other flame retardants, their harm to the environment and people cannot be ignored. In recent years, the research on alkyl phosphinate flame retardants as green and environmentally friendly flame retardants has become one of the hot spots in the development and research of the phosphorus flame retardant industry. The wastewater generated in the production process of phosphorus flame retardants is still harmful to the environment. It is necessary to treat the wastewater before discharging it in a centralized manner. However, the current conventional wastewater treatment equipment simply neutralizes its acidity, collects it in a centralized manner, and then treats it in a unified manner. Due to the poor quality of the pre-treatment of wastewater, the subsequent unified treatment of wastewater is inconvenient, and the wastewater still contains non-toxic liquids. If it is treated as wastewater for unified treatment, it becomes less environmentally friendly. Summary of the invention
