Culture method and apparatus for anaerobic ammonia oxidizing bacteria

摘要

PPROBLEM TO BE SOLVED: To provide a method and equipment for cultivating anaerobic ammonium oxidizing bacteria in which substrates are fed without waste to generate seed sludge with high bacterial cell concentrations and operation is started up within a short time in cultivating anaerobic ammonium oxidizing bacteria with ammonium and nitrite as substrates. PSOLUTION: Equipment 10 for cultivating anaerobic ammonium-oxidizing bacteria, which cultivates, in a cultivation tank 12, novel anaerobic ammonium-oxidizing bacteria that anaerobically denitrifies nitrite and ammonium used as substrates comprises an ammonium feed means 14 which feeds ammonium at a given concentration into the cultivation tank 12, a nitrite feed means 16 which feeds nitrite at a given concentration into the cultivation tank 12 and a controller 22 which controls a feed rate Y of the substrate.
