摘要 ：
A novel double-anammox process for advanced mainstream nitrogen removal was established using step-feed sequencing batch reactor (SBR) system with integration of suspend sludge and biofilms. Following optimization of influent distribution ratio, the effluent total inorganic nitrogen (TIN) was < 10.2 mg N/L, with influent TIN of 43.4 mg N/L, and anammox contributed 71.4% to TIN removal. Biological processes and batch tests revealed that gradient C/N reduction promoted denitratation/anammox in anoxic stage, and simultaneous nitritation and anammox were achieved in oxic stage. Specially, anammox maintained on biofilms with abundance over 109 copies/ (g dry sludge). High-throughput sequencing revealed that Thauera and Nitrosomonas were enriched in flocs. Furthermore, metagenomic sequencing confirmed that Thauera owns narG and napA (NO3--> NO2-) and Nitrosomonas owns amoA (NH4+-> NO2-), support stable NO2- supply for double-anammox. This mainstream anammox-dominant process could potentially be used for stable nitrogen removal in municipal wastewater treatment plants.

摘要 ：
Partial nitrification and partial denitrification combined with anammox is a promising process for sewage treatment. In this study, real municipal wastewater was treated in a continuous two-stage anoxic/oxic (A/O) reactor. External mixed sludge fermentation products were added in the anoxic zone, simultaneously achieving partial nitrification and partial denitrification and achieving a high and relatively stable accumulation of nitrite. The maximum accumulation rates of NO2--N in A1.2 and A2.1-A2.4 zones of the reactor reached 70% and 61%- 37%, respectively, which improved denitrification efficiency and created conditions that supported the coupling of subsequent anammox. The influent nitrogen load of the system was 0.078 kg/(m(3)center dot d), and the mean influent and effluent total nitrogen were 51 and 12 mg/L, respectively. The mean total nitrogen removal rate reached 76%. Further analysis revealed that Hyphomicrobium (incomplete denitrifiers) and Nitrosomonas (ammonia oxidizing bacteria) were enriched, which may have facilitated the high nitrite accumulation. Moreover, the batch test showed that adding sludge fermentation during denitrification significantly suppressed nitrite reduction, resulting in the nitrite accumulation.

摘要 ：
Simultaneous partial nitrification, biological phosphorous removal and sludge fermentation in continuous-flow system faced many challenges in wastewater treatment plants (WWTPs). In this study, a novel process was developed to achieve partial nitrification, enhanced biological phosphorus removal and in-situ fermentation (PNPRF) in continuous-flow system dominated by Tetrasphaera treating low carbon/nitrogen ratio (COD/N) real domestic wastewater. After 80 days of operation, no external carbon was added into the influent. Nitrite accumulation ratio (NAR) reached 99.4% and removal efficiency of PO43- -P was 100%. The effluent concentration of total inorganic nitrogen (TIN) was lower than 2 mg/L. Compared with traditional biological nitrogen and phosphorus removal processes, the daily sludge discharge in continuous-flow PNPRF decreased by 61.9%. DNA concentration of the sludge supernatant after anaerobic zone was 2.26-fold of that before anaerobic zone, and percentages of intact cells decreased by 6.9% and necrotic cells increased by 8.3%, indicating that cell lysis caused the reduction of sludge discharge. The negative effect of prolonged anaerobic phase on transcriptional response of nxrB gene was more significant than that of amoA and hao gene, which resulted in stable partial nitrification. The activities of ammonium-oxidizing bacteria (AOB) were higher than that of nitrite-oxidizing bacteria (NOB), and reverse transcriptional PCR (RT-PCR) showed that RNA expression of AOB was higher than that of NOB. Achieving partial nitrification, enhanced biological phosphorus removal and in-situ fermentation in continuous-flow system dominated by Tetrasphaera solved the problems of carbon source deficiency and large amount of sludge discharge in treating real domestic wastewater process.

摘要 ：
The start-up, efficient, and secure operation of Anammox treating low ammonia sewage, is an important research focus. In this study, a partial nitrification-denitrification coupled with simultaneous Anammox and denitrifi-cation (PND-SAD) process was achieved in sequencing batch reactor/up-flow anaerobic sludge bed (SBR-UASB). The key measures to maintain high efficiency PND were: (i) controlling dissolved oxygen in the SBR below 0.5 mg/L, which is not only conducive to PN, but also promotes the contribution of simultaneous nitrification and denitrification to nitrogen removal; (ii) monitoring the nitrate (NO3--N) of SBR effluent and discharging sludge to wash out nitrate oxidation bacteria when the NO3--N exceeds 1.0 mg/L. The nitrite accumulation rate reached 97.6%. SBR effluent and domestic sewage entered the UASB. Although Candidatus Brocadia only accounted for 0.8%, its contribution to nitrogen removal reached 76.8%. In PND-SAD system, the aerobic HRT was only 3.8 h, nitrogen removal efficiency up to 97.3%.

摘要 ：
The slow initiation of anammox for treating typical domestic wastewater and the relatively high footprint of wastewater treatment infrastructures are major concerns for practical wastewater treatment systems. Herein, a 300 m(3)/d hybrid biofilm reactor (HBR) process was developed and operated with a short hydraulic retention time (HRT) of 8 h. The analysis of the bacterial community demonstrated that anammox were enriched in the anoxic zone of the HBR process. The percentage abundance of Candidatus Brocadia in the total bacterial community of the anoxic zone increased from 0 at Day 1 to 0.33% at Day 130 and then to 2.89% at Day 213. Based upon the activity of anammox bacteria, the removal of ammonia nitrogen (NH4+-N) in the anoxic zone was approximately 15%. This showed that the nitrogen transformation pathway was enhanced in the HBR system through partial anammox process in the anoxic zone. The final effluent contained 12 mg/L chemical oxygen demand (COD), 0.662 mg/L NH4+-N, 7.2 mg/L total nitrogen (TN), and 6 mg/L SS, indicating the effectiveness of the HBR process for treating real domestic wastewater.

摘要 ：
Developing metal-organic framework-incorporated carbon heterostructure (MOF@C) adsorbents with advanced phosphate removal capability is of remarkable significance in satisfying the increasingly stringent wastewater discharge criteria. Nevertheless, the tailored synthesis of MOF@C architectures and related structureperformance modulation remains elusive to date. Herein, we report on the dimensional engineering of MOF@C to prepare ZIF8@single-walled carbon nanotube (SCNT) and ZIF8@reduced graphene oxide (rGO) heterostructures with satisfactory phosphate removal efficiency. The maximum phosphate adsorption capacity of ZIF8@rGO is 491.2 mg g(-1), with the largest partition coefficient value of 1900 mg g(-1) mu M-1 and an initial concentration of 2 mg L-1 under a neutral condition; thus, the prepared heterostructures evidently surpass stateof-the-art adsorbents. The high adsorption capacity is attributable to the two-dimensional graphene support, which provides a more effective surface area for ZIF8 anchoring than that of one-dimensional CNT. Furthermore, phosphate removal on these dimension-engineered MOF@C is examined as a function of pH, system temperature, and coexisting anions. The underlying mechanism is further elucidated via X-ray photoelectron spectroscopy/Xray diffraction analysis and density functional theoretical simulation; enhanced phosphate removal by ZIF8@rGO is mainly attributable to the ligand exchange between the phosphates and the adsorbent. Our findings can aid the design of multifunctional MOF@C adsorbents for efficient phosphate removal from contaminated waterbodies.

摘要 ：
Anammox is sensitive to temperature, which can limit its practical application in wastewater treatment. In this study, a step-feed anoxic-oxic (A/O) process coupled with PD/A was operated steadily from 26.8 degrees C to 13.1 degrees C for wastewater treatment for 200 days. The effluent total inorganic nitrogen (TIN) and phosphorus concentrations were 10.2 mg/L and 0.29 mg/L at C/N ratio of 4.6 and 15.0 degrees C even with increasing nitrogen loading rate (NLR). The anammox activity was 5.60 mg NH4+-N/gMLSS/d even at 14 degrees C, moreover, anammox abundance on the biocarriers increased with decreasing temperature. It was observed that the effect of partial denitrification (PD) was enhanced under low temperature, thus the contribution of anammox for nitrogen removal was improved. The pathway of anammox for nitrogen removal accounted for 48% and the effect of effluent did not deteriorate under low temperature. This study states that PD/A has advantages under low temperature operation, which is suitable for treatment of wastewater with low C/N ratio. (C) 2021 Elsevier B.V. All rights reserved.
