▎ 摘　　要

NOVELTY - Enhanced integrated autotrophic denitrification based on micro-suspension carrier dosing comprises inoculating activated sludge and anaerobic ammonia oxidation sludge into the integrated autotrophic denitrification reaction system, adding micro-suspension carriers into the system during the stirring stage or aeration stage, achieving the interception of micro-suspended carriers and functional microorganisms in the system by gravity separation or membrane separation, and enhancing the biological denitrification of sewage. USE - The method is useful for enhanced integrated autotrophic denitrification based on micro-suspension carrier dosing. ADVANTAGE - The method provides micro-suspension carrier-based high economic benefit, has strong practicability, is capable of long-term efficient and stable operation, shortens culture period of functional bacteria, accelerates process start-up, and improves nitrogen removal efficiency of the system.
