Description

Technical Field

[0001] This utility model relates to the field of treatment tank technology, and in particular to a treatment tank for wastewater containing perfluoride. Background Technology

[0002] Perfluorinated compounds (PFAs) are a class of synthetic organic compounds containing carbon-fluorine bonds. Due to their extremely strong chemical and thermal stability, they are widely used in industrial manufacturing, fire-fighting foams, surfactants, food packaging, and non-stick coatings. However, because of their bioaccumulation, environmental persistence, and potential toxicity, PFAs have been classified as a new type of persistent organic pollutant in recent years, attracting significant attention from many countries and regions worldwide. In industrial production processes, such as fluorochemicals, electroplating, semiconductor cleaning, and textile printing and dyeing, large quantities of highly polluting wastewater containing PFAS are frequently generated.

[0003] Wastewater containing perfluoride can cause serious environmental pollution. The existing announcement, CN 210481080 U, describes a deep treatment device for wastewater containing fluoride. This device includes a reaction tank on one side of a second water pump, a neutralizing agent inlet on one side of a drive motor, a stirring shaft mounted on the output shaft of the drive motor, a heater inside the reaction tank, a settling tank on one side of the reaction tank, a fluoride ion detector inside the settling tank, a circulation pump above the settling tank, and a circulation pipe above the circulation pump. However, in this existing technical document, the wastewater treatment tank occupies a large area, making it inconvenient for use in factories with limited space. Furthermore, the existing technical document lacks stirring during the wastewater filtration and adsorption stage, affecting reaction efficiency. Therefore, this paper proposes a treatment tank for wastewater containing perfluoride. Utility Model Content
