FIELD: technological processes.
SUBSTANCE: invention concerns environmental protection, particularly adsorbent of compound action suitable for obtaining filtering material for both fine sewage purification and complex treatment of exhausted mineral oil. Adsorbent of compound action is obtained by mixing thermal power plant burnout with mineral sediment based on iron oxide-hydroxide extracted at ground water deferrisation plants, and undergoes thermal processing within 180-350°C interval for 3-6 hours. After oil treatment the adsorbent is recovered by heating at 300-350°C for 4-5 hours.
EFFECT: obtaining adsorbent of compound action suitable for both sewage treatment and complex treatment of exhausted mineral oils, from waste.
