A method for treating high-concentration fluorine-containing wastewater by two-stage iron-carbon adsorption-complexation-co-precipitation process |
| abstract |
The invention discloses a method for treating high-concentration fluorine-containing wastewater by a two-stage iron-carbon adsorption-complexation-co-precipitation process. The method is to adjust the pH of the fluorine-containing wastewater to be acidic, and then enter a first-level iron-carbon bed for micro-electrolysis In reaction I, the effluent from the primary iron-carbon bed enters the secondary iron-carbon bed and adjusts the pH to an alkaline condition for micro-electrolysis reaction II. The effluent from the secondary iron-carbon bed undergoes solid-liquid separation to obtain defluorinated water. The method realizes the synergistic effect of various fluoride removal methods, such as adsorption defluorination, complex defluorination and coagulation and precipitation defluorination, and can efficiently defluoride high-concentration fluorine-containing wastewater, and has the advantages of simple process, simple operation and stable operation. , cost-effective and other advantages, is conducive to large-scale industrial production applications. |
