NOVELTY - High-efficient composite self-autotrophy nitration bacteria producing method, involves collecting waste water with high ammonia nitrogen enriched with sludge from autotrophy nitration bacteria, separating and purifying biological bacteria in sludge using flat-panel lineation method, separating and purifying to obtain pure bacterium liquid culture medium for screening, inoculating cultured mature strain, self-maintaining type nitration bacteria needed by growth of the carbon source and nitrogen source, and controlling air flow rate/minute.    USE - The high-efficient composite self-autotrophy method is useful for producing nitration bacteria (claimed).    DETAILED DESCRIPTION - High-efficient composite self-autotrophy nitration bacteria producing method, involves (a) collecting waste water with high ammonia nitrogen enriched with sludge from autotrophy nitration bacteria, (b) separating and purifying biological bacteria in sludge using flat-panel lineation method, where plate culture medium comprises 2 g glucose, 2 g peptone, 1 g yeast extract, 2 g agar powder and 100 ml water, (c) separating and purifying to obtain pure bacterium liquid culture medium for screening, and obtaining more than 90% of ammonia nitrogen removal rate of strain, where the liquid culture medium is as follows: 2 g glucose, 2 g peptone, 1 g yeast extract and 100 ml water, (d) inoculating strain into prepared liquid culture medium of triangular flask at 30 degrees C, (e) inoculating cultured mature strain to fermentation tank equipped with base culture medium for fermentation production, where the basic culture medium comprises 25 kg magnesium sulfate, 25 kg calcium carbonate, 5 kg sodium nitrite, 15 kg sodium chloride, 5 kg manganese sulfate, 5 kg ferrous sulfate, 25 kg diammonium hydrogen phosphate, 25 kg potassium dihydrogen phosphate, trace element, and 10 l or 5 l tap water, self-maintaining type nitration bacteria needed by growth of the carbon source and nitrogen source, and controlling the air flow rate/minute with the volume ratio of 1:1 to obtain product.
