<p>The invention relates to a method of bioremediation of soil and/or soil-based masses polluted with petroleum-derived compounds. In the invention, during the first phase of the first stage of the process the biological waste undergoing biodegradation is arranged into at least one prism along the axis of the aerating ducts and, when the that prism is heated up to the temperature of at least 45 °C, it is overlaid with a layer of soil and/or soil-based mass containing petroleum-derived pollutions in the weight ratio from 6:4 to 8:2, preferably 7:3 and, when the temperature in the prism in such a way is 37 - 45°C, it is left for the period of at least 2 days. Then, every few days, preferably 4, the prism in the known method is mixed, scarified and moisturised to the level of 39-41 % and aerated under pressure in the amount of 10-20 m3, preferably 15 m3 of air counted per 1000 kg s. m. of the prism, preferably with the frequency of 0.5 hour of aeration per 0.5 hour break. Depending on the size of the prism, conducting this process takes from several days up to three weeks till the moment when the microbiological transformation is completed. In the second phase of the first stage of the process according to the invention, the active initiating compost produced in such a way is mixed with soil and/or soil masses containing petroleum-derived pollutions, in the weight ratio from 6:4 to 8:2, preferably 7:3, and, similarly to the first phase of the first stage of the process, it is arranged into at least one prism which is then aerated under pressure and scarified, this process being conducted at the prism heating temperature not lower than 32 °C, until the moment when compost soil containing trace quantities of petroleum-derived pollutions is produced, after which the compost soil produced in such a way is alternatively subjected to humification in the last stage.</p> |
