The results exhibited that AA facilitated the reduction of Fe(III) to Fe(II) and subsequently improved the activation of PAA and H2O2. Various radicals, including organic radicals (e.g. CH3C(O)O• and CH3C(O)OO•) and hydroxyl radical (HO•), were rapidly formed from the activated PAA and H2O2, resulting in SMX removal. Increasing dosages of PAA and Fe(III) contributed to enhanced SMX degradation, while excessive PAA and Fe(III) did not further promote SMX degradation.

Traditional biokinetic approaches (such as Monod, Haldane, etc.) can be challenging, as they require detailed knowledge of the organism's metabolism and the ability to solve numerous kinetic differential equations based on the principles of micro, molecular biology and biochemistry (first engineering principles) which can lead to discrepancies between predicted and actual degradation rates. More recently, data-driven machine-learning techniques have emerged as a promising alternative for modelling microbial systems. A few machine learning models (such as ANN, SVM, RF, DT, XG BOOST, etc.) have been used recently for modelling phenol degradation, but they lack the robustness of generating mathematical models. This gap is addressed in this study using Genetic Programming (GP) as the modelling approach for modelling the phenol degradation. This study utilises the microalgae Acutodesmus Obliquus, finding that phenol degradation of 98% required 216 hours. Both the traditional kinetic approach and the Genetic Programming (GP) approach were used to determine the specific growth rate (µmax) and saturation constant (Ks). It is noted that without any a priori information on the form of the mathematical mode, GP can evolve a model which closely fits the Monod kinetics, thus demonstrating that data-driven models can bring out the first engineering principles on which biokinetic models are dependent or framed in a most swift and effective way. Performance was assessed using root mean square error (RMSE) and correlation coefficient (R), with the GP model showing superior predictive accuracy.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"3065-3076"},"PeriodicalIF":2.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064612","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}

The mechanical properties, including shear strength parameters, unconfined compressive strength, hydraulic conductivity, volumetric shrinkage, and water content, of the solidified sludge were evaluated. The microscopic mechanism of the solidified sludge were investigated through XRD, FTIR, and SEM-EDS techniques. A novel three-layer composite capping cover system for landfills is proposed, comprising an upper capillary barrier layer, a middle drainage layer and a bottom impermeable layer . Indoor rainfall simulation tests were conducted to assess the water retention performance of this capping cover system under repeated moderate, heavy, and torrential rainfall events. The early strength of the solidified sludge exhibited rapid development, with cohesion and internal friction angle reaching 382.56 kPa and 57.67°, respectively, after 3 days. After 28d, the unconfined compressive strength ranged from 6.93 to 14.29 MPa, with hydraulic conductivity between 3.98-23.1 × 10-8cm/s. The hydration reactions of the industrial waste residues resulted in the formation of Ettringite, Gypsum, and hydrous calcium (aluminum) silicates. The Ettringite and Gypsum crystals formed an internal support framework, while the generation of gel-like substances such as C-S-H and C-A-S-H facilitated product aggregation. The RSM was employed to optimise the material ratio of the solidified sludge, while the Pearson coefficient facilitated correlation analysis.

MOF-808-CA with the BET surface area of 653.59 m2 g-1 and the pore volumes of 0.467 cm3 g-1 was successfully synthesized.

The adsorption isotherms and adsorption kinetics of Cr(III) and Cr(III)-EDTA were summarized using Langmuir-Freundlich isothermal adsorption model and the pseudo-second-order model. Even in high salinity wastewater (35,000 mg L-1), MOF-808-CA displayed a strong affinity for Cr(III) and Cr(III)-EDTA. The site energy (E*) values reduced with the increasing of adsorption capacities, and Cr(III) and Cr(III)-EDTA firstly dominated the high-energy adsorption sites before low-energy adsorption sites. The average site energies for the adsorption of Cr(III) and Cr(III)-EDTA by MOF-808-CA were 26.7 and 24 kJ mol-1, respectively, and the differences in the average site energies further illustrated the essential differences in their adsorption mechanisms. The adsorption by electrostatic adsorption and surface complexation were the main adsorption mechanisms for Cr(III) on MOF-808-CA, whereas hydrogen bonding and complexation were the main adsorption mechanisms for Cr(III)-EDTA on MOF-808-CA.

Additionally, composting control groups were set up for each type of straw without inoculation: corn straw (CS), rice straw (RS), and wheat straw (WS). Subsequently, a series of chemical analyses and enzymological methods were used to assess the effects of Glycomyces inoculation on environmental variables, enzyme activities, and organic components. Also, high-throughput sequencing was employed to explore the microbial community composition that greatly contributed to the degradation rate of cellulose and hemicellulose during the degradation process of wheat straw. Finally, the factors influencing the cellulose and hemicellulose degradation in WSI were identified using structural equation models (SEMs). The results showed that cellulose and hemicellulose degradation rates were higher in the Glycomyces-inoculated treatment groups than in the non-inoculated groups. Importantly, the degradation rates of cellulose and hemicellulose in WSI were the highest, at 68.09% and 66.81%, respectively.

By constructing five experimental structures, 240 sets of runoff control rates for rain garden structures were collected to build a database. Feature correlation analysis identified four input parameters: rainfall recurrence interval, storage layer depth, catchment area, and infiltration rate. Using BP, SVM, and Random Forest, initial predictive models for the runoff control effectiveness of rain gardens were established. To enhance the accuracy of the models, the Zebra Optimization Algorithm was employed for optimisation, and model performance was characterised using the coefficient of determination, mean squared error, and mean absolute error. The results show that the ZOA-BP model has the best prediction results on the test set, the prediction accuracy (R2) is 0.979, and the RMSE is 2.331, which verifies the validity of the model.
