Description

Technical Field

[0001] The utility model relates to the technical field of fluorine-containing wastewater treatment, in particular to a fluorine-containing wastewater treatment stirring device. Background Art

[0002] Fluoride-containing wastewater is a common industrial wastewater, mainly coming from the production processes of chemical, electronic, metallurgical and other industries. Since fluoride ions are highly toxic and corrosive, they have serious impacts on the environment and human health, so the treatment of fluoride-containing wastewater has become an important issue in the field of environmental protection.

[0003] Chemical precipitation is a commonly used method for treating fluoride-containing wastewater. By adding appropriate precipitants to the wastewater, fluoride ions react chemically with the precipitants to generate water-insoluble fluoride precipitates, thereby achieving the purpose of removing fluoride ions. Commonly used precipitants include lime, magnesium hydroxide, etc. This method is simple to operate, low in cost, and suitable for large-scale treatment.

[0004] When treating wastewater, the precipitant must first be mixed with the wastewater and then dissolved by stirring. During the stirring and mixing, since the precipitant is directly added to the wastewater, the precipitant must first be broken up before it can be quickly mixed with the wastewater. This process takes a certain amount of time, resulting in the problem of low precipitant mixing efficiency. Utility Model Content
