Acinetobacter junii YB was found to exhibit efficient heterotrophic nitrification and aerobic denitrification ability, with the maximum ammonium, nitrite and nitrate removal rate of 8.82, 8.45 and 7.98 mg/L/h, respectively. Meanwhile, ammonium was found to be removed preferentially in the process of simultaneous nitrification and denitrification in mixed(More)
Traditional process of autotrophic nitrification-anaerobic denitrification usually has problems of long procedure and low efficiency. To overcome these problems, a heterotrophic nitrification-aerobic denitrification bacterium YL was isolated from a domesticated mature SBR reactor with efficient simultaneous nitrification and denitrification ability, and was(More)
Three novel heterotrophic nitrifying bacterial strains, YB, YH and YL were isolated from a laboratory-scale sequencing batch reactor. These strains were identified as Acinetobacter junii YB, Pseudomonas putida YH and Pseudomonas aeruginosa YL, respectively. All three strains exhibited efficient heterotrophic nitrification-aerobic denitrification(More)
This paper describes how to estimate the uncertainty when Fe in metallic silicon is determined by ICP-AES (Inductively Coupled Plasma Atomic Emission Spectrometry). The technique of the averaged moving range (MR) pooled in-statistical-dynamic-monitor is proposed. The study suggests that the uncertainty contribution of ICP-AES measurement system is, by using(More)
