Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an advanced oxidation wastewater treatment device. Background Technology
[0002] With increasingly stringent national environmental standards and requirements for wastewater reuse, traditional wastewater treatment technologies are no longer sufficient to meet technological demands, thus creating a need for advanced wastewater treatment technologies. Advanced oxidation technology is an emerging water treatment technology characterized by the generation of strong oxidizing free radicals and other radicals during the reaction process. Under reaction conditions such as electricity, sound, light irradiation, and catalysts, its oxidation capacity is greatly enhanced, effectively degrading pollutants in water and oxidizing large, difficult-to-degrade organic molecules into low-toxicity or non-toxic small molecules, thus effectively improving the biodegradability of wastewater.
[0003] In practical applications, strong oxidants are required to be added to wastewater during oxidation treatment. These strong oxidants can gradually degrade organic matter in wastewater into simple inorganic substances and oxidize pollutants dissolved in water into substances that are insoluble in water and easily separated from the water. However, when strong oxidants are added to wastewater, they cannot be fully and evenly mixed with the wastewater, resulting in incomplete wastewater treatment and ultimately affecting the effectiveness of wastewater treatment, making it inconvenient to use.
