Evaluation of the Effect of Changing the Composition of Wastewater on Biological Treatment when Adding a Mixture of Sulfide Alkali for the Treatment of Petrochemical Wastewater

Abstract

The influence of a pilot assessment based on the results of a change in the composition of wastewater on the quality of biological wastewater treatment when a sulfide alkali mixture is added to the feedstream of petrochemical enterprises is presented. It was found that the results of wastewater treatment at biological treatment plants are not affected by phenols in sulfide alkali wastewater. It was confirmed that activated sludge retains the ability to extract organic compounds without reference to the proportion of sulfide alkali effluents in the treated water.
