- Abstract:
- In accordance with the requirements of the fluoride removal production process at a wastewater treatment plant, four new types of defluorination agents were evaluated systematically. Two of them, GMS-F3 and YYHBL-Ⅱ, meet the usage requirements of the wastewater treatment plant. By controlling factors such as the amount of defluorination agent, pH, and PAM addition, the fluoride ion concentration can be reduced to below 1.5 mg/L, meeting the level A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Through experimental research and engineering application data analysis, it has been found that small experiments can effectively select defluorination agents in a wastewater treatment plant, and the selected agents can meet production discharge standards. At the same time, this experimental data can also provide good guidance for production practice.
