Streszczenie: W pracy wprowadzono dyspersyjno-konwekcyjny model migracji węglowodorów ropopochodnych w gruntach. Proponowany model jest próbą znalezienia mechanizmu propagacji węglowodorów przez ośrodek porowaty i pozwala przewidzieć, na ile migracja benzenu, toluenu i etylobenzenu jest w stanie zagrozić zwierciadłu wód podziemnych. Uwzględnienie konwekcji w równaniu transportu masy podyktowane jest zwiększoną szybkością migracji węglowodorów w kierunku pionowym. Wprowadzenie równania biosorpcji pozwala uwzględnić wpływ mikroorganizmów na zmianę stężenia, głównie ciężkich węglowodorów ropopochodnych w gruncie. Poprawność modelu zweryfikowano doświadczalnie na modelu filtra gruntowego poprzez wyznaczenie współczynnika dyspersji wzdłużnej dla benzenu, toluenu i etylobenzenu.
Abstract: Dispersion model of NAPL hydrocarbons' transport in porous media has been presented. Mathematical model allows to estimate whether the menace of ground water can occur as a result of hydrocarbons' transport through the soil. The convection in mass transport is considered in the general equation due to the higher velocity of propagation in vertical direction. The introduction of the equation of biosorption link allows to take into account microorganisms' influence on impurities concentration, especially on heavy oils derived compounds. The research conducted on a filter model was the first step to verify the dispersion model of petroleum derived substances. Dispersion coefficient was assessed for benzene, toluene and ethylbenzene.
