In this study, adsorption of the heavy metal ions (Pb(II), Cu(II) and Cd(II)) from water by peanut shells (PS), sawdust (S) commercial activated carbon (AC) were comparatively studied. Thus, relationship between different parameters ion removal rates was investigated. The capacity three adsorbents for increased with an increase in temperature, pH value, contact time, adsorbent dosage, concentration, however, it decreased particle size. All processes are better described Langmuir isotherm or...
Agricultural waste materials (peanut shell and sawdust) were used as replacements for activated carbon to remove heavy metal ions from aqueous solution.Batch adsorption experiments conducted in single, competitive systems.The efficiencies of different were, descending order: lead, copper, cadmium.Activated showed best efficiency (lead: 14.01 mg/g; copper: 13.1 cadmium: 5.5 mg/g), followed by peanut 9.5 49.1 5.07 sawdust 5.3 3.99 which the worst efficiency.The amount adsorbed onto carbon,...
Traditional chemical additives inevitably pollute, damage, and destroy the ecological environment natural resources while simultaneously addressing requirements of engineering construction in loess areas. Additionally, freeze–thaw cycles exert a substantial influence on long‐term durability structures located areas with deposits. Thus, it is considerable benefit to identify utilize materials that are beneficial which will augment engineered performance resistant capacity loess. The purpose...
Utilizing a laboratory model test, this study seeks to evaluate the distribution patterns of volumetric moisture content, soil pressure, and pore water pressure within body red mud dam, given varying initial conditions slope types ratios, during continuous heavy rainfall. The objective is investigate failure mechanisms dam under distinct operational rainfall, thereby offering insights for landslide prevention ensuring construction quality. results suggest that stepped acts as buffer...
Seepage damage is a significant factor leading to red mud tailings dam failures. Laboratory tests on seepage were conducted investigate the characteristics and distribution laws of dams, including soil pressure, infiltration line, pore water displacement, crack evolution. The findings revealed mechanisms slopes, offering insights for safe operation prevention dams. results showed that higher level in dam, position line when it reaches slope face. At highest point surface, increase pressure...
The loss of phosphorous (P) from the land to aquatic systems has polluted waters and threatened food production worldwide. Systematic trend analysis P, a nonrenewable resource, been challenging, primarily due sparse inconsistent historical data. Here, we leveraged intensive hydrometeorological data recent renaissance deep learning approaches fill gaps reconstruct temporal trends. We trained multitask long short-term memory model for total P (TP) using 430 rivers across contiguous United...
Bentonite is widely used as a waterproof material in civil engineering. The swelling capacity and impermeability will be reduced saline water conditions. A polymer-modified bentonite was this study, the characteristic hydraulic conductivity were investigated. Results show that: modified (MB) has good characteristics low permeability conditions; unload strain of MB conditions increased with rising time; final decreased increase vertical pressure increasing initial dry density; and, time...
Suspended sediment concentration (SSC) is a crucial indicator for aquatic ecosystems and reservoir management, but challenging to predict at large scales. This study seeks test the feasibility of deep-network-based models SSC basin outlets given basin-averaged forcings basin-physiographic attributes as inputs, extract insights by interpreting spatially-varying model performances. We trained long short-term memory (LSTM) deep networks either separately each 371 sites across conterminous...
River bathymetry is critical for many aspects of water resources management. We propose and demonstrate a inversion method using deep-learning-based surrogate shallow equations solvers. The uses the convolutional autoencoder with shared-encoder, separate-decoder architecture. It encodes input decodes to separate outputs flow-field variables. A gradient-based optimizer used perform trained surrogate. Two physically-based constraints on both bed elevation value slope have be added as loss...
Electrochemical technology presents a promising approach for phosphorus recovery from wastewater. Nevertheless, its application in industry is hindered by relatively low efficiency, high energy consumption and complex reactor configurations. In this study, coupled electrolysis microfiltration system was designed the shape of iron phosphate compounds with use steel pickling wastewater as source. unit, anode diffusion layer extracted porous surface production an acid effluent alkaline...
In this study, the effect of pH shock during treatment sulfate-containing organic wastewater was investigated using an anaerobic fermentation system reinforced with graphene oxide (GO)/iron series systems. The results show that GO/iron systems exhibited enhanced resistance to shock. Among them, GO/Fe0 had strongest shock, GO/Fe3O4 and GO/Fe2O3 followed close behind, while blank performed worst. After CODCr removal rate, SO4 2- gas production group were significantly improved compared those...
