After 22 days acclimation at 15 mg N/L, the system achieved >90% stable NO3--N removal. Notably, the system demonstrated exceptional stability at a high load of 140 mg N/L, with an average total nitrogen removal rate of 98% (peaking at 99%). This performance indicates a successful adaptation to elevated loading conditions. The high removal efficiency is attributed to the coordinated metabolic processes within the system. As the nitrate load increased, sulfur oxidation accelerated, releasing protons and causing a decline in pH. The ratio of sulfate production to nitrate removal (6.8-10 mg/mg) remained consistent with the theoretical value of 7.54 mg/mg, confirming the integrity of the sulfur metabolic pathway across various loading conditions. Furthermore, the nitrate load acted as a selective pressure, promoting the dominance of Pseudomonadota and Thiobacillus to establish a robust functional microbial ecosystem. In conclusion, this study confirms the viability of the SAD process for treating wastewater with medium to high nitrate concentrations. It also reveals the metabolic and community mechanisms that support performance stability under various load conditions.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-10"},"PeriodicalIF":2.2,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149180184","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}

Model evaluations of oxygen uptake rate (OUR) evolution, together with ammonia and nitrite oxidation profiles, revealed distinct metabolic disruptions. ERY severely impaired the system, dropping overall nitrification efficiency to as low as 25% and halving the growth rates for both AOB and NOB. In contrast, TET exposure largely maintained overall nitrification performance with slightly reduced NOB activity. Under TET stress, the half-saturation constants for ammonia (KNH) and nitrite (KNO) increased to 32 and 2 mg N L-1, respectively, indicating competitive inhibition and decreased substrate affinity. Both antibiotics reduced heterotrophic activity - more severely with ERY-triggering the release and utilisation of hydrolyzable biomass fractions.

The content of protein and polysaccharide in extracellular polymeric substances was determined over time. Excitation-emission matrix fluorescence was used to analyse the types and changes of substances in the system. Resource recovery assessments were conducted by adopting the method of freeze-thaw combined with trituration to extract phycocyanin and determine the content of phycobiliprotein. Photogranule development went through three sequential phases: initially, photogranules were under 1 mm in diameter, with peripheral filaments proliferating to create an irregular, meteorite-like surface; densification: loosely woven filaments contracted, increasing density and reducing surface pits, forming more compact structures; at maturation, granules reached approximately 1.3 mm and became spherical. The system achieved approximately 98% nitrogen and 56% phosphorus removal. Protein and polysaccharide content in extracellular polymeric substances increased slightly over time. Excitation-emission matrix fluorescence showed abundant humic-like substances in the early phase, while microbial byproducts and aromatic proteins remained stable later. The freeze-thaw combined with trituration yielded the highest concentration of phycocyanin (0.31 mg L-1), with phycobiliprotein content stable at about 50 mg L-1.

To address this challenge, this study employed electron beam (EB) irradiation as a pretreatment method. The effects of irradiation dose on sludge dewaterability were systematically investigated, and the multi-dimensional underlying mechanisms were elucidated through integrated multi-scale characterization. The results showed that EB irradiation significantly enhanced dewaterability, with 5 kGy identified as the optimal dose based on a combined evaluation of dewatering performance and specific energy consumption. EB irradiation was shown to efficiently disrupt the protein-stabilized emulsion, likely via water radiolysis-derived free radicals. This process is proposed to drive organic component transformation, surface charge neutralization, protein-lipid co-aggregation and floc reconstruction, ultimately contributing to the conversion of bound water to free water and enhanced dewaterability. These findings clarify the demulsification-dewatering coupling mechanism of EB irradiation on DWAFS and provide a theoretical basis for engineering application in high-fat oily sludge treatment.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-13"},"PeriodicalIF":2.2,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149105947","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}

Inspired by this natural ecological synergy, in the present study, two promising fungal isolates, Trichoderma sp. isolate HR27 and Ganoderma sp. isolate HR31, were isolated and assessed for biocompatibility. Subsequently, their consortium was utilized for single-factorial optimization of various parameters (inoculum size, incubation time, lignocellulosic substrate, temperature, moisture content, pH, surfactant, nitrogen source, co-substrate, and inducer) under solid-state fermentation (SSF) using lignocellulosic waste for enhanced lignocellulolytic enzyme production. The results revealed that a significant increase in enzyme yield was achieved by utilizing wheat straw as the substrate, supplemented with 1.5 g/L Tween 80 and 0.5 mM CuSO4 in Asther's medium with an initial pH of 3.5 at 30˚C.

Compositional analysis revealed that enhanced enzyme production under optimized conditions resulted in 31.7% delignification of wheat straw; however, only 22.9% was observed under unoptimized conditions, compared to that of the raw substrate. The removal of lignin resulted in higher exposure of cellulose (43.25%) and hemicellulose (24.85%) contents in wheat straw under optimized conditions.

In this study, the photo-Fenton process was applied and optimized using Box-Behnken Design (BBD) to treat RO concentrate containing high concentrations of toxic and pollutant species. H2O2/COD, Fe2+/H2O2, and reaction time were selected as operating parameters, while COD, color index (CI), ultraviolet absorbance at 254 nm (UV254), and ultraviolet absorbance at 280 nm (UV280) removal efficiencies were selected as model responses. Statistically, the model's fits were evaluated using variance analysis. Numerical analysis determined the optimum process conditions as H2O2/COD 2.0, Fe2+/H2O2 0.25, and reaction time 68.4 min at pH 3.0.
