The total amount of oily sludge produced by China per year reaches more than 500 ten thousand tons, and the yield of the oily sludge is continuously increased along with the deep exploitation of most oil fields. If the direct discharge occupies a large amount of land, toxic substances contained in the soil pollute water, soil and air, and the ecological environment is deteriorated; directly used for reinjection and when the sewage treatment system circulates, the quality of the injected water is reduced, the running condition of the sewage treatment system is deteriorated, and unpredictable loss is caused to production. Therefore, reasonable disposal of the oily sludge is necessary.
At present, the methods for treating the oily sludge at home and abroad generally comprise an incineration method, a biological treatment method, a heat washing method, a solvent extraction method, a chemical demulsification method, a solid-liquid separation method, a solidification landfill method, super-heated steam, pyrolysis and the like, and various technologies have advantages, disadvantages and adaptability, so that the problems of treatment or environmental pollution of part of the oily sludge can be solved. Wherein the incineration method generates harmful gases such as sulfur, nitrogen and the like, which cause secondary pollution; the biological treatment method needs to mix the oily sludge with the loosening agent, the fertilizer and the bacteria culture liquid, frequently vibrates and naturally ventilates, 97% of petroleum hydrocarbon can be biodegraded within 41 days, and the oil resources are not recycled; the hot washing method is suitable for oily sludge with low clay content and high oil content, but the drainage and residues need further treatment; the solvent extraction method has the problems of long flow, complex process and high treatment cost, and is only suitable for oily sludge containing a large amount of organic matters which are difficult to degrade; the chemical demulsification method needs to add demulsifier and heat the severely emulsified oil-containing sludge; the solid-liquid separation method has low oil recovery rate for the oil-containing sludge with high oil content and serious pollution; the solidification landfill method has simple process, low investment and large treatment capacity, but is difficult to coat petroleum, and has the risk of secondary pollution; the super-heated steam method is characterized in that the super-heated steam method fully contacts the oily sludge through a nozzle, oil-water and solid are separated, the separation efficiency is high, but the scale is small, the cost is high, and the equipment failure rate is high; the pyrolysis method is to decompose macromolecular organic matters into micromolecular hydrocarbon and coke under the conditions of no oxygen and high temperature, and has high requirements on process, equipment and safety, poor oil gas quality, large peculiar smell and dangerous waste residues.
Therefore, the prior art method cannot be popularized and applied in China due to investment, treatment effect, secondary pollution and the like. Therefore, research on a method for efficiently, economically and environmentally treating the oily sludge is urgent.
