Tertiary wastewater treatment using bioreactors-clarifiers

Abstract

The use of technical oxygen instead of air in biological treatment plants can increase their oxidizing ability. Bioreactor-clarifier is a new technical device for tertiary wastewater treatment with the use of oxygen. The design, operation principle and research results of the bioreactor-clarifier for tertiary treatment of urban wastewater are given The use of bioreactors-clarifiers for tertiary treatment of urban wastewater using dissolved technical oxygen allows intensifying the process of biochemical oxidation of organic substances in a contact weighed load and increasing the efficiency of wastewater treatment by BOD and other components.
