NOVELTY - An enrichment culture method for salt-resistant nitrated bacteria colony involves vaccinating active sludge, where culture manner is sequencing batch type enrichment culture; carrying culture in waste water; controlling pH value in aeration tank using sodium carbonate and sodium bicarbonate, and adjusting dissolved oxygen amount; domesticating nitrated bacteria colony by increasing salinity; and when there are not filamentous bacteria in the sludge and the number and the kind of original animals are few, finishing the enrichment culture of the salt-resistant nitrated bacteria colony.    USE - As an enrichment culture method for a salt-resistant nitrated bacteria colony (claimed), which is used in treating high ammonia nitrogen waste water.    ADVANTAGE - The method improves the high ammonia nitrogen wastewater biochemical treatment removal rate, which is suitable for various industrial wastewater with ammonia nitrogen waste water; does not need additional organic carbon source, which greatly saves the investment, so as to reduce the waste water treatment cost; provides wide substrate range, easy culture, high concentration of the cultured salt-resistant nitrated bacteria colony and good activity; clearly improves the removal rate of the high-salt ammonia nitrogen waste water biochemistry treatment; is suitable for processing each kind of ammonia nitrogen industrial waste water and producing in scale; reduces the cost of waste water treatment; and provides good economic benefit and environment benefit.    DETAILED DESCRIPTION - An enrichment culture method for a salt-resistant nitrated bacteria colony, involves vaccinating active sludge, where the culture manner is a sequencing batch type enrichment culture; carrying the enrichment culture in the simulated waste water, where the nutritive salt of the enrichment culture comprises inorganic salt as a main component, the substrate is external ammonium salt, and a carbon source is inorganic carbonate; controlling a pH value in an aeration tank during the enrichment culture procedure by sodium carbonate and sodium bicarbonate, and adjusting a dissolved oxygen amount by an aeration amount; domesticating the nitrated bacteria colony by sequentially increasing a salinity; and when there are not filamentous bacteria in the sludge and the number and the kind of original animals are few, finishing the enrichment culture of the salt-resistant nitrated bacteria colony.
