Industrial reverse osmosis concentrate (ROC) was electrochemically oxidized using a continuous-flow system (CFS) with a front buffer tank. Multivariate optimization including Plackett-Burman design (PBD) and central composite design based on response surface method (CCD-RSM) was implemented to investigate the effects of characteristic (e.g., recirculation ratio (R value), ratio of buffer tank and electrolytic zone (RV value)) and routine (e.g., current density (i), inflow linear velocity (v) and electrode spacing (d)) parameters. R, v values and current density significantly influenced chemical oxygen demand [COD] and NH4+−N removal and effluent ACS level, while electrode spacing and RV value had negligible effects. High chloride content of industrial ROC facilitated the generation of ACS oxidants and subsequent mass transfer, low hydraulic retention time (HRT) of electrolytic cell improved the mass transfer efficiency, and high HRT of buffer tank prolonged the reaction between the pollutants and oxidants. The significance levels of COD removal, energy efficiency, effluent ACS level and toxic byproduct level CCD-RSM models were validated by statistical test results, including higher F value than critical effect value, lower P value than 0.05, low deviation between predicted and observed values, and normal distribution of calculated residuals. The highest pollutant removal was achieved at a high R value, a high current density and a low v value;the highest energy efficiency was achieved at a high R, a low current density and a high v value;the lowest effluent ACS and toxic byproduct levels were achieved at a low R value, a low current density and a high v value. Following the multivariate optimization, the optimum parameters were decided to be v = 1.2 cm h−1, i ≥ 8 mA cm−2, d ≥ 4, RV = 10−20 and R = 1 to achieve better effluent quality (i.e., lower effluent pollutant, ACS and toxic byproduct levels). © 2023, The Authors.

Sulfamethoxazole (SMX), a widely used antibiotic, has triggered increasing attention due to its extensive detection in wastewater effluent, causing serious ecological threats. Herein, a carbon-based heterogeneous catalyst was developed by the O2 plasma-etching process, regulating oxygen-containing functional groups (OFGs) and defects of carbon nanotubes (O-CNT) to activate peroxymonosulfate (PMS) for highly efficient SMX abatement. Through adjusting the etching time, the desired active sites (i.e., C=O and defects) could be rationally created. Experiments collectively suggested that the degradation of SMX was owing to the contribution of synergism by radical (•OH (17.3%) and SO4•– (39.3%)) and non-radical pathways (1O2, 43.4%), which originated from PMS catalyzed by C=O and defects. In addition, the possible degradation products and transformation pathways of SMX in the system were inferred by combining the Fukui function calculations and the LC-MS/MS analysis. And the possible degradation pathway was effective in reducing the environmental toxicity of SMX, as evidenced by the T.E.S.T. software and the micronucleus experiment on Vicia faba root tip. Also, the catalytic system exhibited excellent performance for different antibiotics removal, such as amoxicillin (AMX), carbamazepine (CBZ) and isopropylphenazone (PRP). This study is expected to provide an alternative strategy for antibiotics removal in water decontamination and detoxification. © 2023 Elsevier Ltd

Thorough nitrate removal from reclaimed water by biological techniques without carbon sources is difficult. Flexible, controllable electrochemical nitrate reduction is widely researched. Herein, ultrathin CoO nanosheets were constructed through amino group induction and orientation. The interfacial electron transfer resistance of two-dimensional CoO was 43.4% lower than that of one-dimensional nanoparticles. Iridium loading on CoO (nanosheet) regulated the electronic band structure and generated active atomic H*. The nitrate removal rate increased from 45.1% (CoO (nanoparticle)) and 63.8% (CoO (nanosheet)) to 94.64% (CoO/Ir10wt%). The proton enhancement effect improved indirect nitrate reduction by atomic H* and increased the NO3-N removal rate to 99.8%. Active chlorine species generated by Cl- in the wastewater selectively converted more than 99% of nitrate to N2, exceeding previous Co-based cathode results. In situ DEMS indicated that electrochemical reduction of nitrate included deoxidation (NO3-→*NO2-→*NO→*N/*N2O→N2) and hydrogenation (*NH2→*NH3→NH4+). The NO3-N removal rate of CoO/Ir10wt% exceeded 65% during treatment of wastewater treatment plant effluents, verifying the feasibility of electrochemical nitrate reduction with the CoO/Ir10wt% cathode. A strategy for designing electrochemical nitrate reduction electrocatalysts with excellent potential for full-scale application to treat wastewater treatment plant effluent is provided. © 2023, The Authors.

This study investigated the response of nitrite accumulation to elevated C/N ratio and reveal the nitrite accumulation mechanism during partial denitrification. Results indicated the maximum nitrite accumulation and nitrite transformation ratio (NTR) were 24.70 mg/L and 70.15% at C/N of 3.0, respectively. Nitrite peak would be significantly weakened in high C/N condition (C/N=4.0~5.0). The protein content of TB-EPS reached the maximum at C/N of 2.5~3.0, which might be stimulated by high level of nitrite. Moreover, Thauera and OLB8 were dominated denitrifying species in this region. However, Thauera was further enriched with fading OLB8 in high C/N condition, which enhanced the activity of nitrite reductase (nirK) leading to poor nitrite accumulation. Redundancy analysis (RDA) further indicated NTR was positively correlated to protein content of TB-EPS, denitrifying bacteria (Thauera and OLB8) and nitrate reductase (narG/H/I and napA/B), respectively. On this basis, the potential mechanism for nitrite accumulation was comprehensively elucidated. © 2023, The Authors. All rights reserved.

Can the Ecological Redline Policy Conserve Mangrove More Effectively? Assessment on the Coverage and Carbon Storage in Mangrove of Southern China

SSRN

SSRN 2024年

作者： Liang, Jin Peng, Yisheng Chen, Hanxi Wang, Yafei Xing, Yu Liao, Yan School of Environmental Science and Engineering Guangdong Provincial Key Laboratory of Environmental Pollution Control and Remediation Technology Sun Yat-sen University Guangzhou510006 China Sun Yat-sen University Zhuhai51900 China South China Institute of Environmental Sciences Ministry of Ecology and Environment State Environmental Protection Key Laboratory of Water Environmental Simulation and Pollution Control Guangzhou510655 China

Mangrove ecosystems are famed for their crucial ecological functionalities in moderating the global carbon cycling process. In 2017, the Chinese government implemented the Ecological Redline Policy (ERP) nationwide to protect various ecological functions. However, there is a lack of multi-temporal, high-resolution spatial studies evaluating the effectiveness of ERP in mangrove protection, which hinders sustainable mangrove management. This study focuses on mangroves in Guangdong Province, China, which has the most extensive mangrove distribution in the country, during 2013, 2017, and 2021 using Landsat-8 OLI images (30 m). Field surveys provided data on floral components, forest structure, and biomass of mangrove sites. Subsequently, we assessed the current storage of blue carbon in mangroves using an InVEST Carbon Storage and Sequestration model. Additionally, we estimated the future capacity of blue carbon storage and sequestration under different scenarios of mangrove management. The results revealed a total increase of 2094 ha in mangrove area, with approximately 65.2% of mangroves currently included in the ERP zoning plan. Compared to the Non-Redline zone, the mangrove increment under ERP was higher (1365.55 ha) but with a lower growth rate (20.7%). Conversely, the Non-Redline zone exhibited an increment of 729.32 ha with a growth rate of 38.3%. Furthermore, around 80.0% of carbon storage in mangroves was managed within ERP zones, where the biomass and carbon per unit were at least twice as high as those in the Non-Redline zone. The study suggested that the prevailing ERP planning in China could substantially enhance the function of blue carbon sequestration in mangroves. However, it was evident that the current ERP does not fully meet strategic needs, and it also highlighted the need for optimized planning to minimize tradeoffs between environmental quality and development. © 2024, The Authors.

Sulfamethoxazole (SMX) and its human metabolite N-acetylsulfamethoxazole (N-SMX) are frequently detected in aquatic environments, posing potential threats to freshwater ecosystem health. Constructed wetlands are pivotal for wastewater treatment, with plant species serving as key determinants of pollutant removal efficiency. In this study, wetlands dominated by three submerged plants (Myriophyllum verticillatum, Vallisneria spiralis, Hydrilla verticillata) were respectively constructed to investigate the removal of SMX and N-SMX, and the impact on wetland ecology regarding plant tolerance, microbial response, and nitrogen transformation. Results showed that wetlands removed N-SMX (82.3–99.8 %) more effectively than SMX (54.3–80.2 %), with the wetland dominated by Myriophyllum verticillatum showing the highest removal efficiency. However, high concentrations (5 mg/L) of SMX and N-SMX significantly reduced NH4+-N and TN removal (p © 2024 Elsevier B.V.

Introduction of nanoparticles (NPs) in the solvent was treated an efficient route to enhance mass and heat transfer, therefore, it was a promising strategy to boost carbon dioxide (CO2) absorption and desorption, especially for the biphasic solvent with weak absorption rate and low heat capacity. Herein, powder TiO2 and SiO2 with nanoscale was selected to prepare nanofluid for CO2 capture, based on DMPA-NHD biphasic solvent. The stability of nanofluid and the effect of NPs on CO2 absorption-desorption, phase-splitting was comprehensively explored in this work. Experimental results revealed that 0.06wt% 60nm TiO2 presented excellent performance for CO2 absorption. The liquid film resistance decreased by 11% after introducing NPs, therefore, the maximum mass transfer coefficient is 1.7×10-10 mol·cm-2·s-1·Pa (at 40 °C), increasing by 27% than the blank. In addition, 0.06wt% 50nm SiO2 leaded to significant promotion for CO2 desorption, with the maximum desorption rate at 3.9 mmol/min, and the desorption energy consumption reduced by 9.5% compared with blank case. Importantly, introduction of NPs had no significant effect on the phase splitting behavior, according to the time-profile phase-splitting measurements. The influence of NPs on biphasic solvent behavior was firstly explored to provide a reference for subsequent practice application. © 2023, The Authors. All rights reserved.

Applied Catalysis B: environmental 2025年 377卷

作者： Ye, Wenqiang Wang, Yuepeng Li, Bolang Qin, Xiaoxiao Chen, Xueyan Zhang, Jianghao Chen, Min Zhang, Changbin State Key Joint Laboratory of Environment Simulation and Pollution Control Research Center for Eco-environmental Sciences Chinese Academy of Sciences Beijing100085 China University of Chinese Academy of Sciences Beijing100049 China Beijing100190 China China University of Mining and Technology Xuzhou221116 China

Donor-acceptor (D-A) conjugated organic polymers (COPs) have attracted significant attention in the field of photocatalytic CO2 reduction due to their remarkable performance. Nevertheless, the synthesis of stable and high-performance D-A COPs photocatalysts remains challenging, primarily attributed to the wide variety of monomer structures and diverse coupling methods. In this study, through analysis of the extent of conjugation in aromatic monomers using density functional theory (DFT), benzidine was identified as an electron donor group, and five pyridinomimetic molecules were selected as electron acceptor groups for the construction of efficient D-A COPs catalysts. Via a one-step method at the water/1,2-dichloroethane interface, azo-functionalized COPs photocatalysts (designated as Azo-X;X = DMB (p-Dimethylbenzene), PD (pyridine), PMD (pyrimidine), PZ (pyrazine), TZ (triazine)) were synthesized. The Azo-X showed excellent activity and selectivity under simulated sunlight irradiation in a 1 % CO2 atmosphere and water vapour without adding any sacrificial reagents or photosensitizers. Notably, the Azo-PZ exhibited the highest CO yield rate of 92.8 μmol·g−1·h−1 and maintained stable operation for 120 hours. Further investigation revealed that Azo-PZ exhibited excellent adsorption capabilities for ultra-low concentrations of CO2, which was attributed to the presence of abundant CO2-philic sites. Additionally, due to its robust D-A structure, Azo-PZ displayed the best charge separation efficiency and showed excellent stability. This work provides valuable insights into the design and synthesis of D-A conjugated organic polymer photocatalysts. © 2025 Elsevier B.V.
