Abstract ：
By embedding immobilized biofiller, 100% denitrification efficiency was achieved with nitrate or nitrite as electron acceptors utilizing volatile fatty acids (VFAs) from domestic wastewater after hydrolysis acidification. The consumption patterns of VFAs by functional bacteria and differences in nitrogen metabolic gene expression were thoroughly analyzed. Total consumption of acetic and propionic acids with >95% VFAs utilization was achieved utilizing nitrate, whereas the consumption of butyric and valeric acids was enhanced utilizing nitrite. Denitrification-related genes were all upregulated, particularly nosZ, indicating systemic N2O emission reduction potential. Electron acceptor changes dynamically shifted microbial dominance from Thauera (19.4%) to Thiobacillus (7.2%). These results provide valuable insights into the adaptability and ecological niche characterization of denitrifying bacteria, contributing to improving nitrogen removal efficiency, optimizing carbon source utilization, and reducing sludge production.

Abstract ：
The current sewage treatment systems are typically unable to efficiently remove both nitrogen and phosphorus simultaneously, often compromising biological phosphorus removal to ensure effective nitrogen removal. To resolve this issue, this study establishes an independent enhanced biological phosphorus removal (EBPR) system based on an immobilized fillers nitrogen removal system for treating actual rural sewage. The research focuses on the phosphorus removal performance, operational conditions, and characteristics of the independent EBPR system. When fluctuations occur in the effluent phosphorus concentration, phosphorus-accumulating organisms (PAOs) utilize only 29 % of the available carbon sources, with the remaining carbon being fully consumed by glycogen-accumulating organisms (GAOs). The presence of GAOs and low dissolved oxygen (DO) concentrations leads to deteriorating phosphorus removal performance in the system. To address this, reducing the carbon load and increasing aeration are necessary to maintain effluent phosphorus concentrations below 0.5 mg & sdot;L- 1. Tetrasphaera and Acinetobacter are identified as key microbial genera responsible for phosphate removal in this system. Finally, fluorescence excitation emission matrix parallel factor analysis (EEM-PARAFAC) showed that fermentation microorganisms, represented by Tetrasphaera, played a key role in the removal of tryptophan and tyrosine produced by raw wastewater and microbial metabolism.

Abstract ：
A gel filler with diatomaceous earth, activated carbon, and CaCO3 compounded with polyvinyl alcohol was prepared and optimized. Rapid start-up and efficient and stable operation of partial nitrification (PN) was achieved by immobilization of conventional activated sludge. The results showed that the proper material proportion synergistically improved the performance and oxygen mass transfer rate of the gel. The continuous flow reactor was operated for 10d to successfully start PN, and the maximum ammonia oxidation rate of this filler was 58.30 mg center dot(L center dot h)- 1 during the stable operation, and the nitrite accumulation rate was maintained above 90 %. However, due to the greater mass transfer resistance of unoptimized fillers, more dissolved oxygen waste and nitrogen loss were caused, resulting in delayed expression of biological activity. Based on the kinetic characterization of ammonia-oxidizing bacteria (AOB) within the filler and high-throughput sequencing, it was demonstrated that the rapid start-up and efficient and stable operation of the PN system was due to the highly oxygenophilic and community-dominant position of AOB within this filler. This study provides new options and insights at the level of immobilization technology for the realization and efficient and stable operation of PN.

Abstract ：
A two-stage partial nitritation/anammox process based on microbial encapsulation (PN/A-E) was established. The nitrogen removal characteristics of PN/A-E under high and low ammonia nitrogen and after reactivation following a long-term shutdown were comprehensively investigated and compared with anammox granular sludge (AnGS). The stable PN process did not depend on high ammonia nitrogen, and the nitrite accumulation rate reached 95.2 +/- 0.7 %. The overall nitrogen removal rate of encapsulated anammox bacteria was twice that of the AnGS, and it was more tolerant to external interference. Moreover, PN/A-E showed good reactivation performance, and the total nitrogen in the effluent was 10.0 +/- 1.4 mg center dot L-1 when the final hydraulic retention time was 2.18 h. The immobilized fillers support an increase in ammonia-oxidizing bacteria under restricted conditions and were more conducive to the dominance of functional bacteria and the stability of microbial community under low ammonia nitrogen. This study provides a positive method to achieve a reliable PN/A.

Abstract ：
The treatment performance of anaerobic ammonia oxidation (anammox) immobilized filler on different proportions of domestic wastewater was evaluated. The results showed that, in comparison to synthetic wastewater, 50% domestic wastewater promoted the anammox reaction of immobilized filler, while 100% domestic wastewater had no significant effect on the anammox activity of immobilized filler but the total nitrogen removal efficiency (TNRE) was improved through enhanced denitrification. The TNRE of the immobilized filler was 82.5%, which was significantly higher than that of AnGS (69.7%), and its average anammox contribution rate was more than 90%. This was because the encapsulated anammox biomass could better maintain competitive advantages and coordinate the symbiotic relationship with denitrifying bacteria. Moreover, lower NH4+-N concentration resulted in greater influence of C/N ratio on anammox performance than COD concentration, while the opposite was true at high NH4+-N concentration. This study verified that anammox immobilized filler is effective for mainstream applications.

Abstract ：
To overcome the issue of substandard nitrogen and phosphorus discharge, resulting from the low carbon/ni-trogen (C/N) ratio of municipal wastewater, immobilized filler was used to re-hydrolyze the alkaline fermen-tation liquid of waste activate sludge (WAS) as a nitrogen removing carbon source. The complex organic matter was further hydrolyzed and its denitrification efficiency as a carbon source for nitrogen removal was improved. Volatile fatty acids increased from 1605 & PLUSMN; 5 mg/L to 2546 +/- 37 mg/L after re-hydrolysis of mixed-alkali sludge fermentation liquid, and complex organic matter, such as fulvic acids, humic acids, class I aromatic proteins, and soluble microbial products were hydrolyzed into small-molecule organics. When the re-hydrolysis fermentation liquid (RH-SFL) was used as the carbon source for nitrogen removal, the nitrogen removal effect was close to sodium acetate and the nitrogen removal rate (NRR) was up to 98.5 +/- 0.5%. According to the NOX--N removal curve, the reaction rate of RH-SFL was significantly higher than before re-hydrolysis (nRH-SFL) (0.486 > 0.38). This technology can significantly improve the effective organic quality in the alkaline fermentation liquid of WAS, which can be more easily utilized by denitrifying bacteria. This provides a feasible and effective solution for nitrogen removal in municipal wastewater with insufficient carbon.

Abstract ：
The immobilized carrier was prepared with complete anaerobic ammonia oxidation granular sludge (AnGS) and crushed AnGS, respectively. We evaluated the effects of granular form and continuous temperature changes on nitrogen removal by immobilized anaerobic ammonium oxidation (anammox) filler. The results showed that the rate of nitrogen removal of crushed and encapsulated AnGS was 20% higher than that of direct encapsulated AnGS. However, the latter had higher thresholds of tolerance to Fe2+ and Cu2+. In addition, the immobilization reduced the activation energy of anammox. Above 12.5 degrees C, the immobilized filler was efficient at removing nitrogen removal through the dual adjustment of temperature-hydraulic retention time. From 12.5 degrees C to 23 degrees C, the temperature had a greater influence on the nitrogen removal effect than the HRT. In contrast, HRT had a dominant influence from 23 degrees C to 32 degrees C. Anammox activity was severely inhibited below 12.5 degrees C. High-throughput sequencing analysis showed that the community structure migrated with the changes in temperature. The anammox functional bacteria Candidatus Kuenenia (18.31-39.73%) were the dominant genus at medium and high temperatures, and it was replaced by Chryseobacterium (24.19%) at 8.5 degrees C. In addition, an RDA analysis showed that Candidatus Brocadia was more adaptable to low temperatures than Candidatus Kuenenia. In addition, Bellilinea was more sensitive to temperature than Candidatus Kuenenia. Thus, the temperature could be appropriately lowered to avoid overbreeding. The results of this study optimized the operation of an anammox immobilized system and promote its further application. (C) 2021 Elsevier B.V. All rights reserved.
