Method of biologically purifying liquids contaminated with impurities |
摘要 |
A method of biologically purifying liquids that are heavily contaminated with organic or inorganic impurities, by using bacteria in the presence of a solid support on which bacteria can be fixed, comprises the following steps: the liquid to be purified is continuously injected without prior filtering into a reactor in which a solid support having grain size lying in the range 1 mm to 5 mm and density lying in the range 1.01 g/cm3 to 1.3 g/cm3 has been put into turbulent motion by blowing in gas in the presence of bacteria and while satisfying the conditions required by the metabolism of the bacteria; and the treated liquid is taken continuously from the reactor after a transit time that is long enough to ensure purification of the impurities contained in the liquid to be purified.
