PEAT-DIATOMITE AMELIORANT FOR RECLAMATION OF LANDS CONTAMINATED WITH OIL AND OIL PRODUCTS Russian patent published in 2022 - IPC B09C1/08 

FIELD: agriculture.

SUBSTANCE: invention relates to reclamation and amelioration of lands and can be used in reclamation of soils contaminated with oil, oil sludge and/or oil products and restoration of its fertility directly at the place of contaminant spill, as well as its use as agricultural fertilizer. Peat-diatomite ameliorant for biological destruction of oil hydrocarbons and restoration of soil fertility consists of high-moor peat and diatomite, and sapropel is used as a source of macro and microelements. All components are thoroughly mixed and crushed to fraction of not more than 20 mm at the following ratio of components by weight, %: high-moor peat - 60–80; sapropel - 15–38; diatomite - 2–5. Then the produced mixture is dried till moisture content is not more than 30 %. Invention enables to produce an inexpensive ameliorant capable of biological destruction of oil products and restoration of soil fertility.

EFFECT: ameliorant eliminates removal and transportation of contaminated soil, the need for its recycling, and also minimizes costs of the enterprise associated with payments for negative impact on the environment, ensuring its recovery and ability to process contaminants immediately after their formation.
