Electrophysical Monitoring of the Processes of Electroosmotic Treatment of Soil from Oil Pollution on Laboratory Installations

摘要

This article describes methods and results of laboratory simulation of processes in the clay soils contaminated by oily substances in the samples, on the one-dimensional and three-dimensional physical models. It describes the laboratory setup, the procedure for conducting experiments and processing their results. The possibility of point and integrated prediction of the degree of contamination of the soil on the measurements of its electrical resistance was confirmed. The behavior of changes of porosity, moisture content, granulometric composition of soils contaminated with oil products when there are electrically treated due to thermal and osmotic effects was identified by comparing the data of direct measurements and of electrical control by the system of microprobes. The comparison of results of electrical treatment of the clean soil contaminated with liquid and viscous oil products, as well as by over-exposure to the active substance - solvent was given.
