Description

technical field [0001] The invention relates to the technical field of oil sludge cleaning and treatment, in particular to an oil tank oil sludge cleaning and treatment system. Background technique [0002] In my country's petrochemical industry, for crude oil storage equipment such as oil storage tanks and oil trucks, due to the difficulty in guaranteeing the quality of oil products, an average of 800,000 tons of tank bottom sludge and pool bottom sludge are produced every year. Oily sludge is a large and wide-ranging pollution source, containing pathogenic bacteria, parasites (eggs), heavy metals, salts, polychlorinated biphenyls, dioxins, radionuclides and other refractory toxic and harmful substances. A large amount of oily sludge is produced, and the potential impact on the environment is increasing. The sludge produced has been included in the "National Hazardous Waste Catalog" as oily waste. Since oily sludge is a hazardous waste, random discharge or simple stacking ...
