description The invention relates to a fluorine-containing sulfonate radical wastewater pretreatment process, which comprises: S1, adding sodium hydroxide into fluorine-containing sulfonate radical wastewater, heating to a temperature of 90-95 DEG C, and carrying out a stirring reaction; s2, pumping the wastewater in S1 into a fluorine removal reaction kettle, adding a composite fluorine removal agent and PAC, and stirring for reaction; s3, PAM is added into the wastewater obtained after the reaction in the S2 is completed, precipitates are removed, and supernate enters a subsequent process. The technical barrier of pretreatment of the wastewater containing the fluorosulfonate radicals is broken through, the pretreatment process purposes that the fluorosulfonate radicals are smaller than or equal to 2 ppm and LAS (national standard method) is smaller than or equal to 2 ppm can be achieved, and after pretreatment, the wastewater enters a biochemical treatment system for deep removal of COD, ammonia nitrogen and total nitr
