The invention belongs to the field of environmental protection, and particularly relates to a method for producing petrochemical products by using waste plastics. The method comprises the following steps that waste plastics are sequentially subjected to anhydrous cleaning pretreatment, multi-stage liquefaction, catalytic cracking, hydrofining, secondary cracking and product separation, and different types of petrochemical products are obtained. According to the method provided by the invention, solid waste plastics separated from garbage can be converted into low-carbon olefins, aromatic hydrocarbons, fuel oil and other products by utilizing a series of technological processes such as anhydrous cleaning pretreatment, multi-stage liquefaction, catalytic cracking, hydrofining, secondary cracking and product separation; and high-value utilization of the waste plastics is realized.
