Биопрепараты для очистки почвы от загрязнений на основе отходов органического происхождения

Studies have been carried out to obtain combined biopreparats obtained on the basis of sewage sludge (WWS) and activated carbon (AC) from plant materials for cleaning soils from contaminants with herbicides. The content of organic matter in the settled sludge is 57.3 %. The organic matter of sewage sludge activates its enzymatic activity. Catalase activity in samples treated with combined sorbents, 2.5 to 2.9 times higher than in control soil samples. The combined use of WWS and activated carbons from plant residues significantly accelerates the decomposition of the herbicide. The presence of WWS increases the efficiency of detoxification of the herbicide (active substance metsulfuron-methyl) with active carbons by 1.7 times.
