Shkvirko O. Environmentally safe biological reclamation technologies using sewage sludge

The dissertation research resolved important scientific and practical task setting the optimal conditions of use of the substrate based on sewage sludge for biological reclamation. The experience of Ukraine and the world in the utilization of sewage sludge is analyzed. The most common methods of wastewater disposal in Ukraine and the world are identified. The experience of Ukraine and the world in carrying out biological reclamation is analyzed. The main directions of biological reclamation in Ukraine and the world are determined. Laboratory tests of the substrate with the addition of two types of natural sorbents (zeolite and glauconite) were performed. The positive effect of the substrate with zeolite content on the germination of common barley was established. The positive effect of the substrate with glauconite content on the germination, growth and development of oatgrass was noted. The optimal composition of the substrate for biological reclamation is proposed. Key words: disposal, reclamation, sewage sludge, natural sorbents, zeolite, glauconite, soil, substrate, bioindication.
