The invention discloses an enhanced pre-treatment method for production wastewater of echinocandin antibiotics. The enhanced pre-treatment method comprises the following steps: (1) oxidization treatment: carrying out the oxidization treatment on the production wastewater of the echinocandin antibiotics by adopting a UV (Ultraviolet) united antioxidant under the conditions of normal pressure, room temperature and pH value of 1 to 3 and reacting for 30min to 120min to obtain a solid/liquid mixture; (2) flocculation and sedimentation treatment: adding a flocculation aid to the solid/liquid mixture obtained by the step (1); after mechanically stirring and mixing, gradually flocculating sediment to form a dense floc with a relatively great grain diameter; then, carrying out standing and sedimentation treatment, wherein the staying time is no less than 30min. The enhanced pre-treatment method can be used for efficiently removing COD (Chemical Oxygen Demand) of the wastewater and can also obtain efficient de-colorin
