“…The maximum effectiveness of reagents based on humic acids, which are characterized by a high content of aromatic carbon, hydrophobicity and affinity to petroleum hydrocarbons, is shown (Lesage et al, 2001). Humic acids with iodine solutions are used for better solubility of hydrophobic organic substances and removal of aromatic hydrocarbons from polluted aquifers (Opekunov et al, 2022).…”

It is necessary to find innovative ways to improve the environmental performance of production processes and products. The technology of extracting valuable components from raw materials of plant origin is often used in technological processes of the food, pharmaceutical, chemical and other industries. Extraction is the most energy intensive step. The factors contributing to the extraction of humic acids from plant substrates under the action of electric discharge were studied. The purpose of the work was to study the efficiency of humic acids extraction from the biosubstrate under the action of electric discharges. The physical experiment showed that the main factor influencing the intensity of extraction is the degree of grinding of the solid phase of the biosubstrate-water suspension. The efficiency of electric discharge grinding depends on the pressure amplitude at the distance of the inner radius of the chamber and the number of discharge pulses. It was established that the number of chemical reagents (alkalis), usually used in the process of extracting humic acids from peat, can be reduced many times due to the appearance of radicals and peroxide compounds in the peat-water suspension resulting from the action of an electric discharge. The prospects of the non-thermal electric discharge method of intensification of the extraction of humic acids from biosubstrates were determined.

“…The disposal of industrial wastewater (IWW) has become a problem plaguing the industry due to the difficulty of treating this kind of waste. Different factories may produce different kinds of IWW; if the IWW cannot be treated properly, it will pollute the land around the factory and affect the quality of the nearby soil, which will result in many problems for the environment to a large extent [1][2][3]. Under these circumstances, many methods have been proposed to deal with the IWW to protect the environment, and the methods mainly include two aspects: purification treatment and resource utilization.…”

The disposal of industrial wastewater (IWW) discharged from factories is a significant topic in the environment field, and the use of cement-based materials is a useful way to treat materials with unexpected ions. In this work, IWW with abundant SO42− collected from a factory was utilized to prepare cement mortar (IWWCM), and three kinds of nanomaterials (NMs), including nano-SiO2 (NS), nano-CaCO3 (NC), and nano-metakaolin (NMK), were used to improve the performance of IWWCM. The compressive strengths, hydration degree, hydration products, and micropore structure of the specimens were investigated. The test results showed that IWW reduced the strength of the specimens, and the use of NMs could compensate for this strength reduction. To be specific, the 28-day strength of the freshwater (FW) mixed specimen was 44.6 MPa, and the use of IWW decreased this value to 41.8 MPa. However, the strengths of the specimens with NMs were all higher than 50 MPa, indicating the advantage of NMs for the strengths of the IWWCMs. Moreover, the IWWCM showed a lower hydration degree with a poor pore structure, whereas the use of NMs in IWWCMs refined these properties, explaining the strength increase in the specimens. The results of the SO42− content measurements also showed that the use of NMs could improve the SO42− binding ratio, which is conducive to relieving the pressure of IWW disposal for industrial factories.

“…В загрязненных почвах концентрация НУ ИК в 2-4 раза превышает фоновые показатели, а на расстоянии до 50 м от обочины дороги превышает даже временный региональный норматив (1000 мг/кг) для почв ЯНАО. Высокая буферность торфа определяет низкую радиальную и латеральную миграцию, проявляющуюся на глубину от 25 до 50 см вниз по профилю, и на расстояние до 75-100 м от шоссе, что подтверждает ранее полученные результаты [6]. Так, например, при сильном загрязнении поверхностного слоя 0-20 см НУ ИК до 2000 мг/кг концентрация их на глубине 50 см падает до 16 мг/кг.…”

Дана оценка воздействия автомобильного транспорта на химический состав почв в г. Новый Уренгой и двух участков автомобильной трассы Сургут - Новый Уренгой - Салехард на территории нефтегазовых месторождений севера Западной Сибири. Проведен анализ содержания металлов (Na, K, Ca, Al, Cu, Zn, Fe, Pb, Sr, Sc, Cd, Ni, Co, Cr, V, Ba и Mn), нефтяных углеводородов и полициклических ароматических углеводородов в почвах. Показано, что распространение загрязняющих веществ в торфяниках определяется высокой буферной способностью органогенного слоя и прослеживается на расстоянии до 100 м от автомобильной трассы, радиальная миграция поллютантов в почвенном профиле невелика и не превышает 25-50 см. Индикаторами антропогенного загрязнения служат повышенные концентрации нефтяных углеводородов, бенз(а)пирена, Zn, Pb и Cd, соотношение бенз(a)пирен/бенз(g,h,i)перилен >0.6 в поверхностных горизонтах почв, а также увеличение концентрации Cd, Pb, Zn, Ni, Fe и уменьшение количества Mn в индикаторных видах растений - корке лиственницы Larix sibirica, надземной биомассе багульника Ledum decumbens и в лишайнике Cladonia stellaris.
