Research and development of a method for the remediation of damaged soils using.

Abstract

Methods of synthesizing composites with the participation of natural biological components are attracting increasing attention for the production of sorption functional materials. The paper synthesizes sorption composites based on natural components and technological waste from the woodworking, hydrolysis and chemical industries, containing natural bacteria of the Bacillus subtilis family. Their high adsorption activity has been established in the processes of cleaning and restoration of damaged soil cover by technogenic toxicants, in particular petroleum products. The article examines the global environmental problem of man–made soil pollution, which leads to land degradation and desertification (desertification) - the transformation of once flourishing and fertile territories into deserts without moisture and vegetation. Technogenic pollutants of the soil critically change its chemical composition, physical and biological properties. The aim of the work is to develop an effective method of neutralizing toxicants of various nature using sorbents. A physico-chemical method for the rehabilitation of damaged lands through the use of sorbents is proposed, which make it possible to improve the soil structure and localize the harmful effects of man-made pollutants.
