Method for rapidly forming denitrifying granular sludge and enhancing nitrogen removal of high nitrate nitrogen wastewater

The invention discloses a method for rapidly forming denitrifying granular sludge and enhancing nitrogen removal of high nitrate nitrogen wastewater, and belongs to the technical field of wastewater nitrogen removal treatment. According to the method disclosed by the invention, the succinic acid producing microorganism A.succinogenes is colonized into the sewage sludge, the denitrifying granular sludge is rapidly formed by utilizing the high adhesion and the promoting effect on denitrifying microorganisms, and meanwhile, the denitrifying treatment effect of the high nitrate nitrogen wastewater is enhanced. The method has the advantages of simple operation, no need of additional pH regulation, no secondary pollution, rapid formation of stable whole-process denitrification granular sludge, reduction of the adaptation period of the system to high nitrate nitrogen wastewater, shortening of the sludge domestication culture period, and reduction of the accumulation and discharge of nitrite and other intermediate pr
