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 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.

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.

Results indicated that external surface area, mesopore volume, pore size and surface functional groups were key indicators of GAC adsorption performance. AOM exposure increased the soluble microbial byproducts (SMP) and humic acid components in sand filter effluent, and induced the presence of high molecular weight biopolymers. The removal characteristics of sand filtration effluent spiked with AOM indicated that GAC preferentially adsorbed unsaturated bonds and aromatic compounds, as well as organic acids like fulvic and humic acids. Its adsorption primarily involved physical and chemical processes such as pore filling, hydrophobic interactions, and reactions between chemical functional groups.

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 <i>Glycomyces</i> 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 <i>Glycomyces</i>-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.

This study is based on numerical models of Darcy's law and the Richards equation. A numerical model is used to predict the pollution risk of a certain abandoned metallurgical site. The results indicate that the risk of heavy metal leaching is extremely high under natural conditions, potentially affecting downstream reservoirs after 1500 days. The use of permeable reactive barriers (PRBs) can effectively prevent the migration of heavy metals. However, even with PRBs, 28%-30% of pollutants may still continue to spread outward through lateral flow pathways. The use of impermeable Funnel-and-gate PRB design can effectively reduce lateral pollutant migration, reducing lateral leakage by up to 27%.
