Continuous flow processes for the in situ determination of N 2 O emissions during low C/N municipal wastewater treatment have rarely been reported. The anaerobic/ aerobic/anoxic (AOA) process has recently shown promising potential in energy savings and advanced nitrogen removal, but it still needs to be comprehensively explored in relation to N 2 O emissions for its carbon reduction advantages. In this study, a novel gas-collecting continuous flow reactor was designed to comprehensively evaluate the emissions of N 2 O from the gas and liquid phases of the AOA process. Additionally, the measures of enhancing endogenous denitrification (ED) and self-enriching anaerobic ammonium oxidation (Anammox) were employed to optimize nitrogen removal and achieve N 2 O reduction in the anoxic zone. The results showed that enhanced ED coupled with Anammox led to an increase in the nitrogen removal efficiency (NRE) from 67.65 to 81.96%, an enhancement of the NO 3 − removal rate from 1.76 mgN/(L h) to 3.99 mgN/(L h), and the N 2 O emission factor in the anoxic zone decreased from 0.28 to 0.06%. Impressively, ED eliminated 91.46 ± 2.47% of the dissolved N 2 O from the upstream aerobic zone, and the dissolved N 2 O in the effluent was reduced to less than 0.01 mg/L. This study provides valuable strategies for fully evaluating N 2 O emissions and N 2 O reduction from the AOA process.

“…Patescibacteria positively correlated with some PCB congeners (i.e., PCB008, PCB052, PCB153, PCB105, PCB138, PCB187, and PCB128), pesticides (i.e., lindane, dieldrin and DDE p–p′), PAHs (acenaphthylene, acenaphthene, and pyrene) and HMs (namely, As, Pb, and Mg). Patescibacteria have been previously found to proliferate in soils under the stress of different heavy metals (Tian et al, 2022). Their enrichment in sponge mesohyl in response to anthropogenic activities was previously reported (Busch et al, 2020).…”

This explorative study was aimed at first characterizing the sponge Spongilla lacustris (Linnaeus, 1759) from the sub‐Arctic Pasvik River (Northern Fennoscandia), in terms of associated microbial communities and pollutant accumulation. Persistent organic pollutants were determined in sponge mesohyl tissues, along with the estimation of the microbial enzymatic activity rates, prokaryotic abundance and morphometric traits, and the analysis of the taxonomic bacterial diversity by next‐generation sequencing techniques. The main bacterial groups associated with S. lacustris were Alphaproteobacteria and Gammaproteobacteria, followed by Chloroflexi and Acidobacteria. The structure of the S. lacustris‐associated bacterial communities was in sharp contrast to those of the bacterioplankton, being statistically close to those found in sediments. Dieldrin was measured at higher concentrations in the sponge tissues (3.1 ± 0.4 ng/g) compared to sediment of the same site (0.04 ± 0.03 ng/g). Some taxonomic groups were possibly related to the occurrence of certain contaminants, as was the case of Patescibacteria and dieldrin. Obtained results substantially contribute to the still scarce knowledge of bacterial community diversity, activities, and ecology in freshwater sponges.Practitioner Points Microbial community associated with Spongilla lacustris is probably shaped by the occurrence of certain contaminants, mainly dieldrin and heavy metals. A higher accumulation of dieldrin in the sponge mesohyl tissues than in sediment was determined. S. lacustris is suggested as sponge species to be used as a sentinel of pesticide pollution in the Pasvik River. S. lacustris, living in tight contact with soft substrates, harbored communities more similar to sediment than water communities.
