Oil-contaminated soils under engineering constructions and technology of soil remediation

摘要

Oil around buildings is sucked under them. The conditions for accumulation of oil exist under engineering constructions. It is necessary to clean oil-contaminated territory, whether it is free from infrastructure or under engineering constructions. Cleaning technology with hydrocarbon-reducing micro-organisms was tested on the site of a tank farm with contaminated soils. The sorbent with micro-organisms placed at a depth of 40-60 cm below the technical buildings has cleaned the oil from the soil. The micro-organisms assimilate the n-alkanes with C_(14) chains rather than the C_(32)-C_(40). The oil is destroyed quicker under the constructions than in the open areas.
