The present invention discloses a process wastewater recycling method for forming calcium fluoride from process wastewater containing hydrogen fluoride, which comprises: a metal removal step of extracting and removing one or more metals contained in the process wastewater by mixing the process wastewater and a preset organic solvent; a calcium fluoride sludge forming step of forming calcium fluoride-containing sludge by adding calcium hydroxide to the process wastewater from which the metal has been removed by the metal removal step; and a calcium fluoride sludge recovery step of separating and recovering the calcium fluoride-containing sludge formed by the calcium fluoride sludge forming step.
