THE POSSIBILITY TO STIMULUS MICROORGANISMS BY GUANIBIPHOS SALT IN AEROBIC TREATMENT OF LABORATORY WASTEWATER

Abstract

   The article concerns the results of the influence of low concetration of bioregulator - Guanibiphos on the process of biological treatment of laboratory wastewater. When microorganisms were stimulated by Guanibiphos salt at the concentration of 10-6 g/l, they had higher the ability to remove COD and composition of dissolved organic matter in wastewater than wastewater without salts. Addition of Guanibiphos could improve the activity of dehydrogenase enzyme and biomass of activated sludge.Keywords: laboratory, wastewater, biological, treatment, Guanibiphos, COD
