The remediation technologies of soils contaminated with petroleum products are developed in
two main directions: the first one encompasses searching for new effective bioagents and the
other one explores the ways to activate those microorganisms present in the soil that are
capable of degrading oil. The objective of this research was to determine if it is possible to
increase the effectiveness of biodegradation of petroleum products by using chemical
additives. The soil was supplemented with additives: CuSO4, MnSO4, KMnO4, H2O2, 5% and
10% chemical industry plants sludge, 5% and 10% Stock Company ‘Klaipedos vanduo’
(SC‘KV’) municipal wastewater treatment plants sludge. The data suggest that all the
additives statistically significantly stimulated the degradation of diesel fuel (F = 12.01; p =
.001) and black oil (F = 9.93; p = .001) compared with the control. It was determined that
diesel fuel was degraded the fastest in samples with KMnO4, where efficiency of degradation
was 90%, and 88% efficency in samples with 10% chemical industry plants sludge. Black oil
was degraded the best in samples, where KMnO4 was added: efficiency of degradation was
up to 63%. In the samples with 10% of sewage sludge from chemical industry plant
degradation efficiency was 62%.
