Abstract
The invention relates to an installation for aerobic biological purification of pollutant-containing water, which installation consists of an axial-flow submerged reactor and a sedimentation tank for separation of the biosludge from the purified water. The reactor is a pipe containing a two-stage activated-sludge chamber, which pipe contains (a) a first activated-sludge stage in which a driving-jet nozzle is disposed at the downstream end for the dispersion of the air and the microorganisms in the waste water to be purified, and (b) a second activated-sludge stage in which internals are disposed for homogeneous dispersion of the gas bubbles and the microorganisms as well as for immobilization thereof.
