The efficiency was attained at SA-BPP (1:5), 0.3 g, 180 min, pH 6 and 35°C, with adsorption rates of 83.38% for Cu2+, 77% for Pb2+ and 94.7% for Ni2+.

The thermodynamic analysis shows that the adsorption process is endothermic. The removal efficiency was determined by optimizing the theoretical adsorption experiments through the Box-Behnken Design (BBD).

However, it encounters formidable challenges when applied under nutrient - poor conditions. The efficacy of suspended fillers in augmenting microbial concentrations and enhancing the removal of contaminants had been empirically validated. However, there is limited research on the enhancement of sulphate removal by suspended fillers, and the enhancement mechanism remains unclear. Thus, suspended fill anaerobic bioreactor systems were established to investigate its feasibility under nutrient-poor conditions, and the enhancement mechanisms were further explored. The findings demonstrated that the presence of suspended fillers enabled anaerobic systems to achieve a sulphate removal efficiency of approximately 68.9%, even when the organic load rate was as low as 0.08 gCOD·(L·d)-1. The Principal Coordinates Analysis results clearly demonstrated differences in community composition between sludge and filler samples at each stage (R > 0, P < 0.05). Further analysis of community composition revealed that Desulfobulbus and Desulfobacter, which were closely associated with sulphate removal, exhibited higher relative abundances in the filler samples compared to the sludge samples. Furthermore, the functional genes associated with sulphate removal were found to exhibit more pronounced expression in the sample of fillers. These findings suggested that the presence of suspended fillers creates a favourable environment for certain microorganisms, particularly some sulphate-reducing bacteria, enhancing microbial activity and increasing sulphate removal efficiency.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143729424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated into a capillary system, PfStC achieved 81.73% lead removal, outperforming PwStC (72.33%) and SnStC (59.7%) This high performance is attributed to the synergistic effects of the nanostructured bio-polymers and the capillary action that enhances fluid dynamics within the tubes. The adsorption mechanism involves a combination of ion exchange, complexation, and physical filtration facilitated by the bio-polymeric nanoparticles. The study further highlights the scalability of this approach for large-scale water purification, underscoring its potential for addressing widespread water contamination challenges. Additionally capillary action enhanced flow rates (5.63 × 10⁻⁷ m³/s) and capillary rise (0.0152 m). Spectral analysis revealed that ion exchange and complexation were the dominant mechanisms in lead capture. These findings demonstrated the practical applications of nano bio-polymeric sintered capillary tubes in water purification systems, offering a sustainable and cost-effective solution for real-world heavy metal remediation.

To this end, five EK experiments were designed for a period of nine days by optimising the layout of PRB, periodic replacement of activated carbon and polarity exchange strategy. The results demonstrated that following a nine-day period of EK remediation, the EK3 experiment, in which the PRB was situated in front of the Cd accumulation section and the activated carbon was replaced at 4.5 days, proved effective in both mitigating and shifting the 'focusing' effect of Cd. Furthermore, the highest average Cd removal efficiency was observed to be 31.66%. Cd was concentrated in S3 and S5, is mainly the more hazardous exchangeable and reducible fractions. In contrast, the Cd removal rate in the areas of S1, S2, and S4 reached 70.72% to 77.07%, with the residual Cd predominantly present in the less hazardous oxidizable and residual fractions.

The results revealed that the optimum mass ratio of CS to sawdust was 2:1. Oxygen-containing functional groups in CS were removed, and the fatty structure was degraded. Addition of sawdust promoted the further degradation of CS and migration of various HMs. Metal elements such as Fe, Mg, Co, and Cd had also been detected on its surface. Bacillota (39.05%) was significantly enriched, which effectively improved the microbial community structure. The abundance of species with metal detoxification functions increased. The types and abundance of transporters related to toxic metal ions increased in families such as ATP-binding Cassette Superfamily (ABC) and Resistance-Nodulation-Cell Division Superfamily (RND), which would further aid in cellular homeostasis. Moreover, the addition of sawdust promoted the expression of metal resistance genes (MRGs).

The effects of the main operating parameters on AMX degradation, TOC removal, electrical energy consumption and current efficiency were investigated. Under the optimum operating conditions (initial solution pH of 5.9, PMS concentration of 13 mmol/L, current density of 5.6 mA/cm2), 99.9% of AMX was degraded after 10 min of treatment and 96.8% of TOC was removed after 120 min of treatment.

Comparative experiments with other systems and kinetic analysis have confirmed the superior performance of the 3D-Co3O4/GAC-PMS system for the degradation of AMX. During five cycles, the Co3O4/GAC particle electrode showed excellent stability and long lifetime. The 3D-Co3O4/GAC-PMS system simultaneously degraded 100% of three different pharmaceuticals (amoxicillin, ciprofloxacin and acetaminophen) after 8 min of reaction and removed 88.1% TOC after 120 min of reaction, which suggested the applicability of the system for real wastewater treatment.

A new three-dimensional electrocatalytic oxidation (3D-ECO) system was constructed to treat aged leachate using a composite-loaded metal electrode as the anode, a titanium plate as the cathode, and coconut shell biochar (CBC) as particle electrodes. The conditions for the electrochemical reaction were first optimized, and the pollutant removal effects of the two-dimensional (2D) and 3D systems were compared under optimal conditions. Finally, the electrochemical degradation mechanism was analysed. The results showed that when the initial pH was 5, the current density was 30 mA/cm², the particle addition was 7 g/L, and the electrode plate spacing was 4 cm, the pollutant removal efficiency in the leachate was the highest. At then the removal rates of COD and NH3-N were 90.2% and 30.4%, respectively, while under the same conditions, they in the 2D system were only 41.1% and 17.4%, respectively. The introduction of CBC has increased the removal rate of organic pollutants in leachate by 49.1% and reduced energy consumption by 57.2%. Various active substances such as hydrogen peroxide, hydroxyl radicals, and singlet oxygen played a major role in the degradation of leachate pollutants. The synergy between the anode and the third electrode (75%) enhanced the overall effect of electrochemical degradation of organic pollutants in leachate.

Results indicated that CaO2-LaHyd exhibited maximum adsorption capacities of 66.05 mg·g⁻¹ for P and 230.41 mg·g⁻¹ for Pb. In the simulated capping experiments, the addition of 5% CaO2-LaHyd significantly reduced the phosphate concentrations in the overlying water. The slow release of oxygen from calcium peroxide improves sediment redox conditions, suppresses endogenous P release, and decreases interstitial P levels.

Polymer-based textiles, a significant component of this waste, may persist in landfills without degrading for up to two centuries. This study investigates valorisation of specific blends of textile-based Refuse Derived Fuel (t-RDF) in a novel simultaneous experimental and kinetic analysis to determine pyrolysis product characteristics with process kinetics and thermal parameters. A TGA is initially used to examine the degradation characteristics of t-RDF at three heating rates: 5, 10, and 20 °C.min-1. The kinetics of the non-isothermal pyrolysis of t-RDF are investigated to obtain the activation energy changes that represent the process kinetics for forecasting pyrolysis using the reaction scheme. The average activation energy of the t-RDF, deduced using the Starink model, is found to be 99.22 kJ.mol-1. An in-house designed reactor is used to perform pyrolysis at different temperatures to analyse the effect of compositional variations in the t-RDF. The physicochemical properties of the pyrolysis products are characterised using FTIR spectroscopy, proximate and ultimate analysis, and surface area (BET) analysis. Synthesised t-RDF composition exhibits a heating value of 22.40 ± 3.33 MJ.kg-1, and pyrolysis gas has a heating value of 20.5 ± 1 MJ.m-3, whereas chars are analysed to provide a maximum BET surface area of 32.71 m2.g-1.
