摘要:
A method for collecting bacterial cells comprising: feeding water to be treated containing ammonium and nitrite to an anaerobic ammonium oxidation vessel to denitrify ammonium and nitrite by anaerobic ammonium oxidizing bacteria; and feeding the denitrified treated water to a precipitation vessel, in which an acclimatization container is stored, to cause anaerobic ammonium oxidizing bacteria in the treated water to be attached to an immobilizing material in the acclimatization container, so that the anaerobic ammonium oxidizing bacteria are collected, and, at the same time, to collect anaerobic ammonium oxidizing bacteria in a separated sludge obtained by solid-liquid separation in the precipitation vessel.
