<p>Invention applies to the biological treatment method of waste-water. Its aim is to intensify the purification of waste-water from organic pollution and biogenes, to reduce the volume of electric energy to be supplied for the process and reduce the increase of active sludge in the biological treatment system. The biological treatment method described can be widely used when planning reconstruction of biological treatment plants.The offered method which uses both suspended and immobilized active sludge, as well as aeration of changing intensity, is characteristic with the fact that waste-water is in succession exposed to anaerobic hydrolysis, biosorbtion in a tank with an immovable carrier for immobilization of biomass, simultaneously to nitrification/de-nitrification, post-aeration in a tank with an immovable carrier for immobilization of biomass and making it settle.Fig.1 shows the principal layout of the basic scheme for performing the described method.<IMAGE></p> |
