摘要

A method for culturing at a high concentration nitrifying bacteria contained in activated sludge(sewage sludge, raw sewage sludge, etc.)which comprises nitrifying and acclimatizing the activated sludge under the conditions of an dissolved oxygen concentration of 2 to 4 mg/l, at pH 7.5 to 8.5 and at a temperature of 25 to 35 DEG C for about 1 to 2 months with the use of a treated sludge waste such as filtrate obtained by dehydrating sludge or nitrification waste liquor(ammonia concentration: 100 to 300 mg/l); and continuously sustaining the pH value, which is liable to shift toward the acidic region in the acclimatization process, within a range of from 7.5 to 8.5 by adding a culture promoter comprising a mixture of sodium carbonate and sodium hydrogencarbonate(molar ratio: 4-7:4-8)to thereby acclimatize and accumulate the nitrifying bacteria contained in the active sludge. Thus, nitrifying bacteria contained active sludge can be cultured in a large amount at a high concentration.
