Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a circulating treatment device for further removing fluorine and reducing silicon from coking wastewater. Background Art

[0002] Coking wastewater is a typical toxic and difficult to degrade organic wastewater. The fluoride in coking wastewater usually comes from the fluoride and fluorine-containing additives in the coking raw materials, such as sodium fluoride, calcium fluoride, etc. These fluorides will be discharged with the wastewater to form fluoride-containing wastewater. Fluoride has certain hazards to the environment and human health. Therefore, it is necessary to treat and control the fluoride in coking wastewater.

[0003] Most of the existing methods for defluoridating coking wastewater use defluoridation agents. However, since the stirring shaft of the existing defluoridation device can only stir at a fixed position, the defluoridation agent cannot be evenly mixed with the wastewater, resulting in the defluoridation agent and the fluoride in the wastewater cannot fully react, so the defluoridation effect is poor.
