Provided is a method for decomposing a phenolic by-product, and more particularly, a method for decomposing a phenolic by-product comprising the steps of: supplying a phenolic by-product stream to a decomposition unit for thermal decomposition; separating an upper discharge stream comprising the active ingredient and a lower discharge stream comprising the high boiling point material in the decomposition device; supplying a lower discharge stream from the decomposition device, a side discharge stream from the decomposition device, and a process water stream to a mixing device and mixing the streams; and supplying an effluent stream from the mixing device to a layer separation device in order to separate the stream into an oil phase and an aqueous phase. 提供了一种分解酚类副产物的方法，更具体为一种包括以下步骤的分解酚类副产物的方法：将酚类副产物流供应至分解装置以进行热分解；在所述分解装置中分离包含有效成分的上排出流和包含高沸点材料的下排出流；将来自所述分解装置的下排出流、来自所述分解装置的侧排出流和工艺水流供应至混合装置，并将所述流混合；并且将来自所述混合装置的排出流供应至层分离装置，以便将所述流分离成油相和水相。
