“…Данный тип ремедиации характерен для почв или твердых бытовых отходов, загрязненных летучими поллютантами (нефтепродуктами, летучими углеводородами, хлорсодержащими соединениями и др.) [31]. В Китае паровая экстракция почвыодна из наиболее широко используемых технологий ремедиации нарушенных земель, которая имеет много различных модификаций: сочетание пенной промывки неионогенными поверхностно-активными веществами и паровой экстракции для удаления летучих соединений нефтянной смеси из почвы, загрязненной дизельным топливом [32,33].…”

Introduction. Anthropogenic activities cause large-scale environmental problems. The growing volumes of toxic emissions contribute to soil, water, and air pollution, thus posing a serious threat to all living systems and the global ecosystem. New reclamation methods are a relevant research topic as they help to restore and preserve ecosystems. Study objects and methods. The research covered sixteen years of scientific publications from PubMed of the National Center for Biotechnology Information (USA), Elsevier (Scopus, ScienceDirect), Web of Science, and the national electronic library service eLibrary.ru. Results and discussion. The authors reviewed various scientific publications to define the main technogenic objects that have a toxic effect on biota. Soil is more vulnerable to destructive effects, and mining wastes are responsible for the largest share of technogenically disturbed objects. Pollutants include many compounds, such as heavy metals, hydrocarbons, sulfur compounds, acids, etc. Reclamation technologies reduce the man-induced impact on the environment, e.g. pollutants can be completely or partially destroyed, processed into non-toxic products, completely removed, stabilized into less toxic forms, etc. This review provides information on the main methods of reclamation of disturbed soils and substantiates the prospect of developing integrated reclamation technologies. Conclusion. The present review featured the main pollutants of anthropogenic origin and the traditional soil reclamation methods. The most prospective new technologies of soil reclamation appeared to be a combination of such biological methods as phytoremediation, bioaugmentation, and biostimulation.

“…Soil has high specific heat capacity; it is a poor conductor of heat. In T-SVE, direct thermal contact heating with resistance is usually a slow process [24]. At the beginning, the soil was just stirred with water, the overall temperature was relatively uniform, about 28 • C. After the system was heated up for 90 min, the temperature of the middle soil layer around the heating rod began to change obviously.…”

“…Tasca [23] combined ultrasound irradiation with the electrochemical generation of •OH by Nb/BDD anode to remove Chlorpyrifos from aqueous solutions in threedimensional electrochemical reactor. Li Xiaoya [24] took the hydrocarbon-contaminated soil as the treatment object and carried out the research on the enhanced SVE technology based on resistance heating in the three-dimensional box device. The research showed that the space setting of the heating rod significantly affected the removal effect of pollutants.…”

In order to describe the changes of soil temperature field, air flow field and remediation situation with time during the process of thermally enhanced SVE (soil vapor extraction), a remediation experiment of benzene contaminated soil with single extraction pipe was carried out in a box device. The results showed that the whole temperature of the system was raised to 80 °C in 4 h. 43% of benzene were removed in the first 2% of the extraction time. After 24 h, the repair efficiency was close to 100%. The device can efficiently remove benzene from soil. By continuously monitoring the parameters in the operation process of the system, the spatial distribution of temperature and soil gas pollutant concentration with time was plotted. It showed the benzene concentration distribution in the soil gas was more consistent with the temperature distribution before the start of ventilation, and the concentration of benzene in the soil gas dropped rapidly after ventilation, while the temperature distribution was almost unaffected. In the treatment of soil with a benzene content of 17.8 mg∙kg−1, when the soil gas benzene concentration is the highest at 180 min, the peak value is 11,200 mg∙m−3, and the average concentration is 7629.4 mg∙m−3.

“…Depending on the size of the pool and the type of liquid, it is possible to estimate the level of hazard and to establish a dangerous zone (Piecuch et al 2015, Stefana et al 2016. These actions require the knowledge of soil permeability and liquid evaporation rate (Moon et al 2018, Yu et al 2019, Singh et al 2020. The intensity of evaporation process depends on the type of liquid.…”

The influence of sun rays, wind speed, and different type of subsoil on the evaporation process was analyzed. A dedicated experimental set-up for investigation of evaporation process of three liquids (ethanol, petrol and tap water) deposited on glass and sand was created. Results indicated that for porous surfaces wind decreased the amount of evaporated liquids. After substitution of wind with sun rays for porous surface evaporation process increased for ethanol and petrol, respectively. Finally, the influence of both wind and sun rays indicated a 1% and 5% decrease of evaporation intensity for tap water and petrol, respectively. While, a 2% increase of evaporated liquid was observed for ethanol. It was noticed that application of porous surface caused the highest improvement of evaporation process for petrol and tap water, while the lowest for ethanol. Moreover, application of wind together with porous surface increased the intensity of evaporation for all analyzed liquids.
