摘要
Biological treatment of suspension in bioreactor comprises feeding horizontal jet(s) of fluid superimposing on the vertical flow in the bottom part of the bioreactor to establish a spiral flow to the central outlet area of the bioreactor. The bioreactor has central outlet area near the bottom. At least some of the suspension is routed through vertically aligned guide zone to circulate the suspension. Biological treatment of suspension in bioreactor (2) comprises feeding horizontal jet(s) of fluid superimposing on the vertical flow in the bottom part of the bioreactor to establish a spiral flow to the central outlet (17) area of the bioreactor. The bioreactor has central outlet area near the bottom. At least some of the suspension is routed through vertically aligned guide zone to circulate the suspension. The suspension is routed so that a vertical flow of portion(s) of the suspension is produced. The vertical flow of portion(s) of the suspension extends into the vicinity of the bottom of the bioreactor or proceeds from the vicinity of the bottom of the bioreactor. An independent claim is included for suspension biological treatment device comprising bioreactor for receiving the suspension, vertically aligned guide mechanisms in the interior of the bioreactor extending into the vicinity of the bottom region of the bioreactor for circulating the suspension, and nozzle (11, 13) for feeding fluid into the bioreactor in the vicinity of the bottom of the bioreactor.
