[PMID: 38925404 DOI: 10.1016/j.biortech.2024.131041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 06/15/2024] [Accepted: 06/24/2024] [Indexed: 06/28/2024]
Abstract
To effectively treat actual ammonia-rich Chinese medicine residue (CMR) resource utilization wastewater, we optimized an anaerobic-microaerobic two-stage expanded granular sludge bed (EGSB) and moving bed sequencing batch reactor (MBSBR) combined process. By controlling dissolved oxygen (DO) levels, impressive removal efficiencies were achieved. Microaeration, contrasting with anaerobic conditions, bolstered dehydrogenase activity, enhanced electron transfer, and enriched the functional microorganism community. The increased relative abundance of Synergistetes and Proteobacteria facilitated hydrolytic acidification and fostered nitrogen and phosphorus removal. Furthermore, we examined the impact of DO concentration in MBSBR on pollutant removal and microbial metabolic activity, pinpointing 2.5 mg/L as the optimal DO concentration for superior removal performance and energy conservation.

Li T, Yang XL, Song HL, Xu H, Chen QL. Quinones contained in wastewater as redox mediators for the synergistic removal of azo dye in microbial fuel cells. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 301:113924. [PMID: 34731947 DOI: 10.1016/j.jenvman.2021.113924] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/14/2021] [Accepted: 10/06/2021] [Indexed: 06/13/2023]
Abstract
The present paper aimed to investigate the roles of quinones contained in wastewater and the enhanced effects on microbial fuel cells (MFCs) under different redox conditions. The feasibility of using wastewater rich in quinones to act as co-substrate and redox mediators (RMs) library to strengthen the synergistic removal of azo dye in MFCs was evaluated. The results demonstrated that quinones achieved enhanced effects on electricity generation and COD removal of MFC better at higher current intensity. The addition of pure quinone decreased electron transfer resistance (Rct) of MFCs from 4.76 Ω to 2.13 Ω under 1000 Ω resistance and 1.16 Ω-0.75 Ω under 50 Ω resistance. Meanwhile, higher coulombic efficiency was achieved. Compared with sodium acetate, using quinone-rich traditional Chinese medicine (TCM) wastewater as the co-substrate enhanced the synergistic removal of reactive red 2 (RR2) in MFCs from 79.58% to 92.45% during 24 h. RR2 was also degraded more thoroughly due to the accelerated electron transfer process mediated by RMs. Microbial community analysis demonstrated that the presence of quinone in TCM wastewater can enrich different exoelectrogens under varied redox conditions and thus influenced the enhanced effects on MFC. Metagenomic functional prediction results further indicated that the abundance of functional genes involved in carbohydrate metabolism, membrane transport metabolism, biofilm formation, and stress tolerance increased significantly in presence of RMs. Redundancy analyses revealed that RMs addition was the more important factor driving the variation of the microorganism community. This study revealed the potential effect of quinones as redox mediators on the bioelectrochemical system for pollutants removal.

Effects of reflux ratio on the anaerobic sludge and microbial social behaviors in an expanded granular sludge bed reactor: From the perspective of acyl-homoserine lactones-mediated quorum sensing. BIORESOURCE TECHNOLOGY 2021; 337:125360.

Abstract
Performance of anaerobic sludge and microbial social behaviors in an expanded granular sludge bed (EGSB) were evaluated by increasing reflux ratio from 50% to 500% stage by stage, with a constant influent chemical oxygen demand (COD) of 5500 mg/L at hydraulic retention time 12 h. The results indicated that the reflux ratio of 100% - 200% was more favorable for the EGSB with a methane production of 2.4 m3/m3·d. It was found that acyl-homoserine lactones (AHLs)-mediated quorum sensing (QS) could balance various microbial populations in the anaerobic digestion process. C4-HSL and C8-HSL were identified as the specific AHLs in enhancing granulation of anaerobic sludge by stimulating protein secretion into extracellular polymeric substances (EPS). 3-oxo-C6-HSL and 3-oxo-C14-HSL were verified for the enhancement of methanogenesis. The present study showed a novel perspective on the performance of EGSB with reflux ratios based on the AHLs-mediated QS.

Efficient treatment of traditional Chinese pharmaceutical wastewater using a pilot-scale spiral symmetry stream anaerobic bioreactor compared with internal circulation reactor.

Abstract
It is a technical barrier to efficiently treat traditional Chinese pharmaceutical (TCP) wastewater, due to its high chemical oxygen demanding (COD) concentration (>5000 mg/L). This study proposed and employed a spiral symmetry stream anaerobic bioreactor (SSSAB) to treat TCP wastewater. Results showed that a pilot-scale SSSAB (150 L) could achieve COD removal efficiency of 94.8% and volumetric removal rate (VRR) of 19.7 ± 0.7 kg COD·(m³·d)-1 under room temperature, which were much higher than operation performance in internal circulation (IC) anaerobic reactor (COD removal efficiency and VRR were 85% and 11.3 ± 0.8 kg COD·(m³·d)-1, respectively). The maximum COD volume removal rate could attain 43.4 kg COD·(m³·d)-1. The characteristics of granular sludge in SSSAB were investigated from both temporal and spatial scales. During the operation period, the anaerobic granular sludge in SSSAB was of higher concentration and superior properties compared to the IC anaerobic reactor. The sludge concentration exhibited a spatially decline trend, decreasing from 61 g L-1 in the bottom to 34 g·L-1at the top of the bed, yet the average biomass concentration was still higher than that in IC reactor. According to shock tests with fluctuated real wastewater. the resistance of SSSAB to hydraulic and loading shock was up to 4.3 m h-1 and 42 (kg COD· h) · (m3)-1, respectively. The study demonstrated the proposed SSSAB is a promising reactor to treat high-concentration TCP wastewater.

Abstract
Biodegradation of traditional Chinese medicine (TCM) wastewater was investigated in a pilot-scale anaerobic-anoxic-aerobic combined process, which was composed of an expanded granular sludge blanket (EGSB) reactor, a hydrolysis acidification (HA) reactor and a biological contact oxidation (BCO) reactor. In stable stage, the average values of COD and color in the combined process effluent were 45.7mgL-1 and 13 times, respectively. Excellent linear relations (R2>0.915) were achieved between color and UV254 at three color levels. Comprehensive community structures of the combined process were analysed by Illumina MiSeq Sequencing, which revealed that microbial community in the aerobic reactor had the greatest diversity and richness. Bacteroidetes, Firmicutes and Proteobacteria were dominant phyla in the three reactors, and Bacteroidales, Geobacter, ZB2 were the predominant functional microorganisms in the anaerobic, anoxic and aerobic reactors, respectively. Good removal efficiencies and presence of core microorganisms confirmed that the combined process was feasible for treating TCM wastewater.

Abstract
A novel integrated system of anoxic-pure oxygen microbubble-activated sludge reactor-moving bed biofilm reactor was employed in treatment of real coal gasification wastewater. The results showed the integrated system had efficient performance of pollutants removal in short hydraulic retention time. While pure oxygen microbubble with the flow rate of 1.5 L/h and NaHCO3 dosage ratio of 2:1 (amount NaHCO3 to NH4 (+)-N ratio, mol: mol) were used, the removal efficiencies of COD, total phenols (TPh) and NH4 (+)-N reached 90, 95, and 95 %, respectively, with the influent loading rates of 3.4 kg COD/(m(3) d), 0.81 kg TPh/(m(3) d), and 0.28 kg NH4 (+)-N/(m(3) d). With the recycle ratio of 300 %, the concentrations of NO2 (-)-N and NO3 (-)-N in effluent decreased to 12 and 59 mg/L, respectively. Meanwhile, pure oxygen microbubble significantly improved the enzymatic activities and affected the effluent organic compositions and reduced the foam expansion. Thus, the novel integrated system with efficient, stable, and economical advantages was suitable for engineering application.

Abstract
The start-up procedures and characteristics of the granular sludge from a novel double circle (DC) anaerobic reactor for treating traditional Chinese medicine (TCM) wastewater were investigated. Following a start-up period, the DC reactor demonstrated good chemical oxygen demand removal at 96.87%. The Fourier transform infrared spectra and excitation-emission matrix (EEM) fluorescence spectra from the soluble microbial products of the effluent showed that amino acid and aromatic compounds in TCM wastewater were effectively removed by the DC reactor. The peak of the particle size distribution from the granular sludge in the first reaction area of the DC reactor ranged from 700 to 1500 µm with a mean size of 513 µm, and the mean size of the granular sludge in the second reaction area was approximately 250 µm. The protein-like peak in the EEM fluorescence clearly decreased and the coenzyme F420 of the fluorescence peak clearly increased for the extracellular polymeric substances of the granular sludge.
