METHOD OF PURIFICATION OF SOIL CONTAMINATED BY OIL PRODUCTS

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to blasting jobs and can be used in recultivation of lands contaminated by oil products. Proposed method comprises placing explosives in soil with blasting and initiation appliances. Depth of soil contamination is determined and mole drains are arranged at the contamination boundary depth with spacing not exceeding drain depth. Mix of propane with surplus content of pressurised oxygen is used to burn oil products. Drains are laid in two stages: first, a line of parallel drains is laid all over the area. Then drains perpendicular to those laid at the first stage are laid. Now, reinforced polyethylene envelopments are placed to be filled with pressurised surplus oxygen. ^ EFFECT: invention allows complete burning out of oil products. ^ 2 dwg, 1 ex
