 A method of using the oil sludge cleaning agent of Example 1: in the first cleaning container (cleaning tank) with a mechanical stirring device, add the oil sludge to be treated and the soil eluent at a mass ratio of 1:4, and heat it at a temperature of 75 ° C. , under the condition of stirring speed of 500rpm, after stirring for 0.5-1h, keep it at constant temperature for 0.5-1h, the mixed system is divided into three layers, the upper layer is the crude oil washed out, the middle layer is the water layer, and the lower layer is the muddy water system; take the upper layer of crude oil and To be recovered, the muddy water system is filtered with a screen to remove large-sized stones, organic matter and other sundries in the sludge. The filtered muddy water system is subjected to high-speed centrifugation, and the water phase obtained by centrifugation is transported to the first cleaning tank for recycling. Collect the desorbed sludge in the lower layer after centrifuga...
