The invention provides a treatment method of whitening agent wastewater, and relates to the technical field of industrial wastewater treatment. Comprising the following steps: S1, pumping various fluorescent whitening agent wastewater into a wastewater mixing tank; s2, introducing the uniformly mixed fluorescent whitening agent wastewater into an acidification tank by using a pump, and stirring; s3, after uniform stirring, 20% hydrochloric acid is dropwise added at a constant speed; s4, feeding into a filtering device, and filtering; s5, directly feeding the filtrate obtained in the step 4 into an oxidation tank, and introducing ozone for oxidation; s6, ozone is connected to an ozone processor through a pipeline; s7, determining ozone introduction time according to the COD of the whitening agent wastewater; and S8, after ventilation is finished, the wastewater directly enters a biochemical water reservoir. By arranging the cleaning part, the guide part and the clamping part, automatic switching and automatic
