Claims (6)

1. Способ очистки загрязненного нефтепродуктами грунта, включающий смешение грунта с гидрофобным сорбентом, последующее добавление воды и отделение всплывшего сорбента, отличающийся тем, что в качестве сорбента используют терморасщепленный графит.1. The method of purification of soil contaminated with oil products, including mixing the soil with a hydrophobic sorbent, the subsequent addition of water and separation of the surfaced sorbent, characterized in that thermally-split graphite is used as the sorbent. 2. Способ по п. 1, отличающийся тем, что терморасщепленный графит используют в виде хлопьев или гранул с насыпной плотностью 2-10 кг/м3.2. The method according to p. 1, characterized in that the thermally split graphite is used in the form of flakes or granules with a bulk density of 2-10 kg / m 3 . 3. Способ по п. 1, отличающийся тем, что объемное соотношение грунта и терморасщепленного графита составляет от 1 : 0,1 до 1 : 2, а время перемешивания грунта с терморасщепленным графитом составляет 3-5 мин. 3. The method according to p. 1, characterized in that the volume ratio of soil and thermally split graphite is from 1: 0.1 to 1: 2, and the mixing time of the soil with thermally split graphite is 3-5 minutes 4. Способ по п. 1, отличающийся тем, что при перемешивании грунта и терморасщепленного графита дополнительно добавляют экстрагент и/или осуществляют электрокавитацию или ультразвуковую кавитацию. 4. The method according to p. 1, characterized in that when mixing the soil and thermally split graphite, an extractant is additionally added and / or electrocavitation or ultrasonic cavitation is carried out. 5. Способ по пп. 1-4, отличающийся тем, что сорбент регенерируют путем термической возгонки поглощенных нефтепродуктов и повторно используют для очистки грунта. 5. The method according to PP. 1-4, characterized in that the sorbent is regenerated by thermal sublimation of the absorbed oil products and reused for cleaning the soil. 6. Способ по пп. 1-4, отличающийся тем, что отработавший терморасщеплeнный графит отжимают и отделяют нефтепродукты, а отжатый сорбент после термической обработки повторно используют для очистки грунта. 6. The method according to PP. 1-4, characterized in that the spent thermally split graphite is pressed and oil products are separated, and the pressed sorbent after heat treatment is reused for cleaning the soil.
