Synergy between autotrophic denitrification and Anammox driven by FeS in a fluidized bed bioreactor for advanced nitrogen removal

Jingde Ma et al.

Summary: The novel ferrous sulfide (FeS)-driven autotrophic denitrification (AuDen) and anaerobic ammonium oxidation (Anammox) coupled system (FS-DADAS) shows promising nitrogen removal performance, achieving over 80% total nitrogen (TN) removal in laboratory testing. The system demonstrated stable denitrification effects over long-term operation, with 100% NO3--N removal and NH4+-N concentrations lower than 8.11 mg L-1 in the effluent.

Exploration and verification of the feasibility of sulfide-driven partial denitrification coupled with anammox for wastewater treatment

Yang-Fan Deng et al.

Summary: A sulfide-driven partial denitrification and anammox (SPDA) process was developed and operated continuously with stable performance for 392 days, achieving 80% nitrogen removal efficiency. Sulfide had inhibitory effects on anammox activity, but rapid oxidation by sulfur-oxidizing bacteria relieved these effects. High-throughput sequencing identified Thiobacillus and Sulfurimonas as dominant SOB genera, and Candidatus Kuenenia as the dominant anammox bacteria in the SPDA system, laying the foundation for future practical applications.

Ionic copper strengthens the toxicity of tetrabromobisphenol A (TBBPA) to denitrification by decreasing substrate transport and electron transfer

Rui Wan et al.

Summary: This study investigated the combined effect of TBBPA and Cu on model denitrifying bacteria, finding that Cu intensified the toxicity of TBBPA to denitrification by stimulating EPS secretion, blocking glucose transport, suppressing key enzyme activity, and down-regulating gene expression related to electron transport. These effects led to decreased bacterial growth, insufficient electron donor, and lower electron transport activity, causing a synergistic toxic effect of TBBPA and Cu on denitrification. Overall, this study provides new insights into the combined impact of BFRs and HMs on microorganisms.

Effect of Fe3+ on the sludge properties and microbial community structure in a lab-scale A2O process

Lanhe Zhang et al.

Summary: This study demonstrated that an appropriate concentration of Fe3+ can enhance the removal efficiencies of COD and TN in wastewater treatment, while excessive concentration may lead to inhibition. Furthermore, the positive correlation between Fe3+ concentration and TP removal was attributed to the increased surface roughness for enhanced phosphorus adsorption onto activated sludge. Thauera was identified as the dominant bacterial genus, and certain bacteria showed good adaptability to high concentration of Fe3+ within the bacterial community. Gene families related to Carbohydrate Metabolism, Amino Acid Metabolism, Cell Motility, Membrane Transport, and Replication and Repair were found to be the most abundant functional genes in the metabolic pathways.
