摘要: The invention is directed to a process for the aerobic purification of waste water in a reactor containing unsupported granular active sludge. The oxygen necessary for maintaining aerobic conditions within the reactor is provided in the form of an oxygen-containing gas. The oxygen-containing gas is preferably introduced into the reactor at such a place that the oxygen-containing gas provides at least some mixing action in the reactor. The invention also provides a reactor suitable for this process.
