In the multi-step-process the 1st activation step is carried out as an adsorption step, with a sludge loading of at least 2 kg BOD 5/kg dry solids day, aerobically or opt. anaerobically. Procaryonts are used as the working bio-mass. The bio-zoonoses of the 1st- and subsequent activation steps are sepd. - Novelty consists in constantly supplying procaryonts, as replenishing bio-mass, with the crude waste water, to the adsorption step. The amt. of procaryonts is at least 1 wt.% vol. of the bio-mass vol. unit of this step. |
