Heterotrophic nitrification-aerobic denitrification arthrobacterium and application thereof

The invention discloses a heterotrophic nitrification-aerobic denitrification arthrobacterium and application in denitrification of wastewater. The bacteria strain is Arthrobacter sp. WZUF01, and is preserved into Common Microorganism Center of China General Microbiological Culture Collection Center; the registration number in the collection center is CGMCC NO.14012. The bacteria strain has the advantages that the nitrogen in the nitrogen-containing wastewater is removed, the pH (potential of hydrogen) and temperature application ranges are broader, the carbon and nitrogen mass ratio is lower, and the higher content of dissolved oxygen can be endured; the high concentration of ammonia can be endured, the wastewater with NH4-N concentration more than 300mg/L from a culture farm after anaerobic digestion can be treated, the treatment result meets the pollutant emission standard of livestock and poultry culture industry (GB18596-2001), and the final product is nitrogen; the gathering ability is good; the Arth
