Embodiment 1
[0032] A method for advanced treatment of fluorine-containing wastewater, comprising the steps of:
[0033] (1) Preprocessing section:
[0034] S1: Fluoride-containing wastewater (fluorine ion content is 400mg / L) enters the 1# reaction pool, and according to the pH of the wastewater, add a pH regulator such as hydrochloric acid or liquid alkali to the 1# reaction pool to adjust the pH value of the wastewater to 7.5- 8. Stay for 10 minutes;
[0035] S2: Introduce the upper wastewater treated by the 1# reaction pool into the 2# reaction pool, and add the high-efficiency defluoridation agent GMS-F1 and the reaction catalyst to the 2# reaction pool according to the content of fluoride ions in the wastewater, among which, GMS-F1 The mass ratio of the dosing mass of the catalyst to the mass of fluoride ions in the waste water is 18:1, the mass ratio of the mass of the reaction catalyst to the mass of fluorine ions in the waste water is 0.1:1, and the upper layer of waste water is i...
