ABSTRACT:
The present invention can feed substrates without waste to generate seed sludge with high bacterial cell concentrations and can start up operation within a short time, in cultivating anaerobic ammonium oxidizing bacteria with ammonium and nitrite as substrates. Equipment for cultivating anaerobic ammonium-oxidizing bacteria, which cultivates, in a cultivation tank, novel anaerobic ammonium-oxidizing bacteria that anaerobically denitrify nitrite and ammonium used as substrates, comprises an ammonium feed device which feeds ammonium at a given concentration into the cultivation tank, a nitrite feed device which feeds nitrite at a given concentration into the cultivation tank, and a control device which controls a feed rate Y of the substrate.
