Zusammenfassung:Existing sewage treatment plants use technologies and treatment methods that do not always provide efficient and reliable wastewater treatment from organic contamination. Among the current methods and principles of wastewater treatment, biological methods, which are considered to be the most promising and environmentally sound, occupy a significant place, therefore, the intensification of biological wastewater treatment is an important task. In order to improve the efficiency of biological wastewater treatment processes, a method of biological activation the microorganisms of active sludge has been proposed, which has significant advantages over other methods. However, the lack of a sufficient scientific and technical base, the use of carboxylic acids to activate the active sludge causes the need for research on the effects of acids on wastewater treatment processes. Experimental studies of the effectiveness of biological stimulation of active sludge’s bacteria with carboxylic acids are presented, theoretically and experimentally justifying the feasibility of consistent use for the treatment of active sludge by lemon and amber acids. The proposed method of intensification of biological wastewater treatment allows us to improve the efficiency of treatment in aeration tanks compared to biological cleansing without the addition of carboxylic acids. In addition, the use of carboxylic acids can have a comprehensive impact on cleaning processes: boost enzyme formation, suppress the development of filamentous bacteria, increase resistance to toxic pollution.
