Methodology for thermal desorption treatment of local soil pollution by oil products at the facilities of the mineral resource industry

The analysis of the main environmental consequences leaks and local spills petroleum products at enterprises mineral resource complex is presented. It established that problem soil contamination with facilities other industries caused by significant volumes consumption types oil products. Based on results author's previous field research, a series experiments was carried out, consisting in modeling artificial pollution such as gasoline, diesel fuel, highly refined oil, motor transmission followed their purification heat treatment temperatures 150, 200, 250 °C. °C limit heating temperature set due to need partially preserve structure quality after its fertility. When processing rises 450 °C, all humates are completely burned out and, result, productivity lost. Confirmation provided determine humus content uncontaminated treated different temperatures. found maximum about 50 % initial organic carbon preserved. According conducted experimental studies, dependences required concentration reduce an acceptable level have been established. methodology thermal desorption cleaning soils varying degrees
