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":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-01-29","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}

Rain gardens are widely used in new urban construction because they effectively control surface runoff from rainwater, thereby reducing waterlogging. The runoff control effectiveness of rain gardens is influenced by multiple factors. This paper predicts the runoff effects of rain gardens using multiple models. 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. This research outcome can provide references for the application of rain gardens and is expected to reduce the design and operational costs of related projects.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064629","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}

After the experiments carried out, it was shown that the concentration of metals in solution influences the separation of equal charges, where increasing the current has no influence on the separation of the metals studied, but that the application of cycles with the cation concentrate generated can lead to the separation of Ni without the addition of any chemical reagent.

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. This study provides valuable data for designing landfill solidified sludge cover systems and offers a new approach for the co-disposal of sludge and industrial waste.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-17"},"PeriodicalIF":2.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052089","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}

Results indicated that calcination at 700 °C for 60 min was determined to be the optimal thermal activation condition for magnesite. Under the optimal operating conditions of the DAS (flow rate: 0.4 mL/min, filling mass ratio: thermal activation magnesite to pine shavings = 1:1), the system achieved complete removal (100%) of metal ions within 396 h while maintaining a pH above 7.0. Moreover, it significantly minimized operating costs and sludge generation.

This study investigates the potential of indigenous cyanobacterial strains Oscillatoria pseudogeminata, Oscillatoria proteus, Oscillatoria trichoides, and Lyngbya ceylanica for the bioremediation of DWW. Under controlled laboratory conditions, these strains were assessed for their uptake capabilities for 15 days.

Biochemical analyses indicated a decrease in biomass, chlorophyll a, carotenoids, proteins, and carbohydrates in DWW relative to the growth of cyanobacteria in BG 11 media. This decline may hinder the effectiveness of cyanobacterial in wastewater remediation. The findings highlight the efficacy of selected cyanobacteria in nutrient removal from DWW, emphasizing their dual role in nutrient uptake through biosorption mechanism and biomass generation.

The study evaluated the performance of CS-CG stabilised soil through unconfined compressive strength (UCS) tests at 7 and 28 days, six dry-wet cycles, a 30-day water immersion test, pH test, swell rate test, XRD, SEM, and MIP analyses. A UCS prediction model for CS-CG stabilised soil under dry-wet cycles was established. Results showed that CS-CG-10%-(70:30) achieved a UCS of 5.87 MPa after 28 days, decreasing to 4.77 MPa after six dry-wet cycles, indicating excellent bearing capacity and water stability. Increasing CS content improved UCS after 30 days' immersion, reaching 5.74 MPa for CS-CG-10%-(70:30). The CS-CG mix produced hydration products like C-(A)-S-H gel, Ca(OH)2 crystals, and ettringite, enhancing pore structure and UCS. More dry-wet cycles increased hydration products and pore diameter, causing an initial UCS drop before stabilisation.

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. Collectively, total nitrogen and the microbial community structure of the top 30 genera contributing to cellulose and hemicellulose degradation were important factors influencing the straw degradation of WSI.
