PROCESS AND APPARATUS FOR THE BIOLOGICAL PURIFICATION OF SEWAGE

摘要

A process for biological waste water treatment is indicated, by means of which waste water (AW) containing dissolved pollutants and air (LT) are both fed to a reactor (1) via at least two mutually separate nozzles (3, 4). The streams of the two-component mixture emanating from the nozzles (3, 4) are, to achieve high mass transfer in the reactor (1) passed along in such a way that they impinge therein on one another in an impingement zone (PZ). The waste water (AW) is passed from the reactor (1) into a settling vessel (8) in which the biosludge settles out.
