The existing oil depot is mainly treated by adopting an oil separation tank-coagulation air flotation-filtration process, the coagulation air flotation process in the set of process flow can remove colloid substances such as dispersed oil, emulsified oil and the like in the sewage by adding conventional coagulants such as polyaluminium chloride (PAC), Polyacrylamide (PAM) and the like and combining an air flotation device, and after the oil-containing sewage of the oil depot is subjected to oil removal treatment through water quality analysis, a large amount of benzene series substances are still contained in the water, so that the organic matter (COD) in the sewage seriously exceeds the standard.
