Abstract

A találmány tárgya eljárás szennyvíz biológiai kezelésére, amelyneksorán egy eleveniszapból és szennyvízből álló keveréket egy aktiválásilépésben gázzal kezelnek, és az eleveniszapot a kezelt szennyvíztőlflotációval elválasztják. Az aktiválási lépésben az eleveniszapkoncentrációját <6 g/l-re állítják be, és a flotációt dekompressziósflotációval végzik. Ó
