Treatment method for removing water and impurities from automobile waste oil liquid

The invention discloses a treatment method for removing water and impurities from automobile waste oil liquid, which is realized through a steel anti-explosion oil collecting tank and specifically comprises the following steps of: 1, collecting the waste oil liquid of a scraped automobile, and feeding the waste oil liquid into the steel anti-explosion oil collecting tank through an oil inlet; secondly, the waste oil liquid sequentially passes through a filtering layer, an upper water absorption layer and a lower water absorption layer to be subjected to impurity removal and water absorption, and then enters the space below the lower water absorption layer; thirdly, sampling is conducted through a sampling pipe, and if the oil product is qualified, collecting is conducted through an oil outlet pipe; and if the oil product is unqualified, the oil product is collected through a waste liquid discharge pipe. According to the invention, different functional cores are arranged on the annular support frame, so that w
