The invention belongs to the bioengineering technical field, in particular relating to an aquatic Comamonas sp. strain and application of the aquatic Comamonas sp. strain in short-range nitration-denitrification denitrogenation during the biological denitrogenation process of waste water. The aquatic Comamonas sp. strain is Comamonas aquatica LNL3 and preserved in 'China General Microbiological Culture Collection Center of the China Committee of Culture Collection for Microorganisms' on January 24th, 2008, with a collection number of CGMCC No.2361. The strain is collected from a hydrophyte root zone in a water body in Jinshan Lake of Zhenjiang, a open water zone in a water body in the Jinshan Lake and deposits of the Jinshan Lake, is separated, and can be grown in a basal culture medium which takes CO2 as a carbon source and energy or CO2 and an organic substance as a mixed carbon source and the energy and takes ammonia nitrogen or nitrate nitrogen as a nitrogen source.
