摘要:The constant development of the technosphere leads to negative consequences, such as environment pollution by components with toxic properties and violation of natural biosphere processes. The most significant negative effect of the functioning of the oil and gas production and processing complex is soil pollution. This article is devoted to the study of the features of the electrochemical cleaning process in various types of soils contaminated by oil and reservoir waters. The mechanisms of the hydrocarbons amount decrease are described. The greatest contribution is made by electrokinetic processes as well as by direct and indirect oxidation. The dependence of the content of petroleum hydrocarbons on the amount of transmitted electricity in several types of soil (clay, loam, chernozem and sand) is established. It has been established that there is the limit quantity of charge required for effective cleaning of each type of soil. This parameter primarily depends on the soil characteristics. It was revealed that at a high soil moisture the voltage differences are insignificant. The efficiency of cleaning for each type of soil was calculated. The clay soil has optimal conditions for electrical treatment (cleaning efficiency is 84.5%). The cleaning efficiency of sand soil was minimal.
