Establishment of rapid nitrite accumulation by adopting the combined strategy of anoxic starvation and free ammonia inhibition

This paper examined the feasibility of rapid nitrite accumulation through short-term anoxic starvation combined with high FA inhibition strategy. It was hypothesised that the combined inhibition strategy could achieve rapid and efficient enrichment of AOB and continuous and efficient inhibition of NOB, and shorten the start-up time of nitritation.
