TECHNOLOGY FOR REMEDIATION OF PETROLEUM-POLLUTED SOIL BY COMBINED USE OF EXPANDED PERLITE, GEL AND AN ORGANIC FERTILIZER

摘要

The invention relates to a method for remediation of petroleum-polluted soil by the combined use of expanded perlite, gel and an organic fertilizer, without requiring important soil mass dislocations and conveyance to specialized stations for performing the needed treatments. According to the invention, the method has the following stages: performing drilled networks (A) with a depth of maximum 1 m which are uniformly distributed on the surface (B) of the soil (1) to be remedied, filling a third of the drilled depth with granular expanded perlite (4), administering a mixture (3) of gel and expanded perlite on the second third of the drilled depth, filling the drilled network, up to the zero level, with a mixture (2) of expanded perlite and organic fertilizer, and performing all the sowing preparation works on the surface of the soil (1), followed by the actual sowing of the soil (1).
