Description
Technical Field
The invention belongs to the technical field of wastewater treatment, and particularly relates to a method and a device for treating fluorine-containing wastewater.
Background
Chemical precipitation is a common technology for treating fluorine-containing wastewater, and the basic principle is that a specific chemical reagent, such as calcium salt or aluminum salt, is added into the wastewater to chemically react with fluorine ions in the water to generate insoluble fluoride precipitates. These precipitates can then be separated from the water by physical means such as sedimentation, filtration, etc., thereby achieving the purpose of removing fluorine. When the treatment is carried out, firstly, necessary pretreatment such as pH value adjustment, suspended matters removal and the like is carried out on the fluorine-containing wastewater so as to improve the subsequent treatment efficiency. Then adding proper amount of calcium salt (such as calcium chloride and calcium sulfate) or aluminum salt (such as aluminum sulfate and aluminum chloride) into the pretreated wastewater. These chemicals react with fluoride ions in water to form calcium fluoride or aluminum fluoride precipitates. Under the proper pH value and temperature conditions, the fluoride ions react with calcium ions or aluminum ions to generate insoluble fluoride precipitates. The reaction equation is as follows, for calcium salt Ca2++ 2F- & gtCaF 2 × and for aluminum salt Al3++ 3F- & gtAlF 3 ×. And (3) sedimentation separation, namely gradually settling the generated fluoride sediment to the bottom of the container under the action of gravity to form a sediment layer. And solid-liquid separation, namely separating the sediment from the supernatant liquid by sedimentation, filtration and other methods to obtain treated water with low fluorine content and fluoride sediment.
The consistency of the fluorine-containing wastewater depends on the type and concentration of fluoride dissolved therein, as well as other dissolved or suspended matter present. The high viscosity fluorine-containing wastewater may contain high concentrations of fluoride or other viscosity-increasing substances such as high molecular weight polymers, organic or inorganic salts. The problem with the prior art is that it is critical to ensure a rapid and uniform distribution of chemical agents into the wastewater when treating fluorine-containing wastewater with a relatively high viscosity.
