The invention discloses a treatment and recycling method for chloromethylated bead production wastewater and belongs to the technical field of chemical wastewater treatment. The method solves the problems of high treatment cost, rigorous treatment conditions, no appropriate recycling method and the like of the chloromethylated bead production wastewater at present. The method comprises the steps of distilling the chloromethylated bead production wastewater at 90-110 DEG C to recover methanol, reducing a COD (chemical oxygen demand) of raw water, regulating pH (potential of hydrogen) to 0.1-0.3, adding ferrous salt and oxidant in sequence, after reaction for 2-5h at 50-80 DEG C, and preparing a composite coagulant polymeric ferric chlorosulfate solution, wherein an Fe3+ content in the coagulant solution reaches above 150g/L; the coagulant solution is applicable to general industrial wastewater treatment; and a removal rate of the solution for industrial wastewater with the COD greater than 500mg/L is greater than 60%. The treatment method of the chloromethylated bead production wastewater is simple in process flow and operation, saves wastewater treatment cost, achieves waste recycling and is applicable to industrial production.
