PROCESS FOR THE MICROBIOLOGICAL RECLAMATION OF SOIL CONTAMINATED WITH OIL OR OIL-PRODUCTS

This biological treatment method of soil polluted by oil and oil products consists in inserting organic and mineral fertilisers into polluted soil, tilling the polluted soil periodically ploughing and cultivating it, airing and irrigating it. The novelty is that prior to soil cultivation, an oil oxygenising micro-organism complex (NOM) is inserted, which consists of strains subject to Bacillus, Rhodococcus, Serratia, Acetobacter, Trichoderma, Pseudomonas genus types, and it is extracted from the oil and oil products polluted soil, for instance, in the final stage cleaning soil polluted by black oil, of water suspension, which has 1-10 - 1-10 NOM cells in 1 ml, and an optimal NOM amount in the soil being cleaned (300-350 ml./g of cleaning soil) is supported by inserting a NOM complex water suspension into it at least twice within the interval of no more than 30 days using approximately 3 I water NOM complex suspension in not more than 1 m of the treated soil surface area, when the temperature of the soil is between 8 degrees Celsius and 40 degrees Celsius.
