Abstract
Methods for cleaning and neutralizing liquid production wastes are largely determined by the specifics of the enterprise and the physicochemical properties of the circulating substances. Wastes from organic synthesis enterprises containing benzene, toluene, xylene and similar substances are as a rule subjected to mechanical and physico-chemical methods of purification. Wastewater containing difficult-to-oxidize impurities undergoes a multi-stage biological treatment, which can sufficiently oxidize the alcohols and carboxylic acids contained in the wastewater. In some cases, after complete biological treatment, to reduce color and destroy difficult-to-oxidize components, methods of deeper purification are used: coagulation, filtration, ion exchange, ozonation, etc. However, the presence of aromatic hydrocarbons in liquid waste reduces the effectiveness of biological methods and leads to the need for additional use of mechanical, chemical and physicochemical methods (sorption, distillation, ion exchange) or their combinations for complex purification and utilization.
