VERFAHREN UND VORRICHTUNG ZUR BIOLOGISCHEN BEHANDLUNG VON ABWASSER
摘要
<p>Effluents are treated by with heterotrophic or autotrophic micro-organisms, the activated sludge process and the use of algae for purifying waste water. The concentration of the micro-organisms is increased to reduce the structural volume of the reactors. In addition, the separation of suspended matter is improved. The waste water is separated from the micro-organisms by filtration in the biological reactor or in a following stage. By preference, a granular filter layer is used. During the filtration process, this filter layer is cleansed by a special regeneration device. <IMAGE></p>
