Transport of composite heavy metals in the soil profile is a complex process that poses significant risks to groundwater and deep soil layer. This study conducts an in-depth simulation and analysis of Cd transport behavior in single and composite contamination through soil penetrate tests and leaching tests, combined with the HYDRUS and CXTFIT models. The study found that Pb significantly promoted the transport rate of Cd in the soil profile, reducing the initial breakthrough time from 12 to 5 pore volumes (PV). During leaching, the presence of Pb increased the Cd concentration in the pore water by 70.2 %, further enhancing Cd's transport potential and groundwater contamination risk. The study further validated the applicability of the HYDRUS model, finding that Pb promotes the proportion of the instantaneous equilibrium site (f) and the first-order reaction rate coefficient (α) of Cd. An increase in the instantaneous adsorption ratio of heavy metals accelerates the adsorption process from the kinetic control phase. By incorporating competitive adsorption isotherms and heavy metal speciation into the HYDRUS prediction model, the model achieved a high prediction accuracy (R = 0.84) for heavy metal transport pathways in polluted sites, providing a reliable tool for the long-term evolution prediction of polluted sites.

In this study, the combined system of peroxymonosulfate and chloride (PMS/Cl−) was applied to chemically clean the irreversible humic acid-fouled polyethersulfone (PES) membranes. A 94% flux recovery and 96% resistance removal of the fouled membrane were reached after soaking for an hour in PMS/Cl− solution (10 mM/15 mM) at 25 oC under neutral conditions. The almost constant surface properties of virgin and cleaned membranes by characterization indicate that the PMS/Cl− process can effectively remove irreversible foulants with minimal impact on membrane materials. Diminution of the peaks centered in the region of fulvic-like and humic-like components, monitored under 3D-fluorescence for the cleaning solution, demonstrated that structural changes in hydrophobic substances dominated the foulant detachment. The presence of the PMS-catalyzed chlorination of the foulants in the cleaning process was confirmed after detecting PMS and hypochlorous acid (HClO) concentrations in the combined system. Furthermore, lower toxicity was observed with the PMS/Cl− method compared to hypochlorite alone, as evidenced by monitoring halogenated by-product formation and acute toxicity to Photobacterium phosphoreum T3. Overall, the novel chemical cleaning system exhibits promising prospects for the efficient and environmentally friendly removal of irreversible organic foulants in the practical water treatment process. © 2023, The Authors.

Due to the complex composition of the oil flowing through the refining unit, the equipment anticorrosion work has always been a major problem in petrochemical enterprises, and the corrosion problem is a key factor related to shortening the service life of the atmospheric and vacuum distillation unit. Aiming at the problem of high temperature corrosion of atmospheric and vacuum unit in a petrochemical enterprise and the current situation of corrosion management in the enterprise, this paper designs a high temperature corrosion diagnosis system of atmospheric and vacuum unit based on Forcecontrol configuration development platform. The system uses threedimensional interpolation algorithm to calculate the corrosion rate, and uses Microsoft SQL sever2014 database technology and Forcecontrol 7.1 configuration development platform to realize the comprehensive management of corrosion data, corrosion rate calculation, early warning, expert advice and other functions. Through the function test of each module in the system, and using the actual corrosion data provided by the enterprise to simulate and verify the system, the test results show that the system can achieve the expected functions, and ensure the calculation accuracy of corrosion rate.

Optimizing KH 2 PO 4 addition to enhance nitrogen retention in swine manure composting: Integrated mechanisms of enzyme activity, microbial community, and denitrification genes

引用

Journal of Environmental Chemical engineering 2025年第5期13卷

作者： Xiaoxia Hao Lijia Jiang Du Jin Mengting Chen Wenyi Wang Dongmei Jiang Lin Bai Lab of Animal Ecology and Environmental Control College of Animal Science and Technology Sichuan Agricultural University Chengdu 611130 PR China State Key Laboratory of Swine and Poultry Breeding Industry College of Animal Science and Technology Sichuan Agricultural University PR China

The effects of different potassium dihydrogen phosphate (KH₂PO₄) ratios on nitrogen loss mitigation, enzyme activities, denitrification gene expression, and microbial community composition during swine manure composting remain unclear. This study established four KH₂PO₄ treatment ratios: CK (0 %), T1 (3 %), T2 (6 %), and T3 (9 %). The results showed that KH₂PO₄ enhanced specific nitrogen fractions, with NH₄⁺-N and NO₃⁻-N levels 1.6–2.6 fold and 0.4–1.6 fold higher than CK during the cooling and maturity periods, respectively. Total Kjeldahl nitrogen (TKN) content also increased significantly ( P  < 0.05), reaching 7.7 % - 10.1 % higher than CK. However, high KH₂PO₄ concentration (9 %) negatively impacted nitrogen retention, leading to a reduction of 18.8 percentage points in TKN compared to CK. Furthermore, the addition of KH₂PO₄ enhanced the activities of functional enzymes (AMO, protease, N₂OR), reduced denitrification-associated microorganisms (e.g., Planifilum and Bacillus ), and inhibited microbial processes related to nitrate reduction, nitrite denitrification, denitrification, and nitrite respiration, thus mitigating nitrogen loss. The 3 % KH₂PO₄ treatment was the most effective, showing the lowest abundance of denitrification genes ( narG , nirK , norB , nosZ ) ( P  < 0.05). Microbial network analysis revealed that KH₂PO₄ enriched key species involved in nitrogen transformation. Mantel test analysis highlighted that functional enzymes and bacterial communities were the main drivers of nitrogen transformation. These findings suggest that KH₂PO₄ improves nitrogen retention in compost and enhances its agricultural value.

In this paper, linear active disturbance rejection controller and nonlinear active disturbance rejection controller are designed for variable geometry turbine(VGT) and exhaust gas recirculation(EGR) system in diesel engine. The double-input double-output(DIDO) VGT-EGR system is designed as two single-input single-output(SISO) systems, in which the crosscoupling and unmodelled dynamics are considered as disturbances and decoupled through estimation and compensation. Through simulation, it is indicated that nonlinear active disturbance rejection controller has better tracking performance, disturbance resistance performance and robustness.

Today, developing photocatalysts with high sterilization efficiency is still an urgent ***, SnSe samples with sphere, rod, plate, and surface wrinkled morphology were synthesized by a simple solvothermal method. The samples were denoted as SnSe-1, SnSe-2, SnSe-3, and SnSe-4, respectively. The morphology and size of the prepared samples greatly relied on the choice of surfactant and the reaction time. Among the prepared samples, SnSe-1 showed the best photothermal effect (41.4%) and reactive oxygen species generating ability during the 808 nm laser irradiation. Consequently, SnSe-1 exhibited sterilization rates of 99.99% against Gram-negative Escherichia coli (E. coli) and Gram-positive Bacillus subtilis (B. subtilis) during NIR irradiation (1.5 W/cm 2 ， 10 min) at a relatively low concentration (25 µg/mL). The result suggests that SnSe-1 nanoparticle with a spherical shape could be used as an effective antibacterial agent for the treatment of bacterial contamination, including rapid bacterial sterilization in water. © 2022, The Authors.

Iron-nitride based materials are considered to be one of the most promising anode materials for Lithium-ion batteries (LIBs) due to their good electrical conductivity and high theoretical capacity. However, iron-based nitrides are easily pulverized in the long-term lithiation/delithiation process, which reduces the electrochemical stability and limits their large-scale application. Here, we report a Fe3N or Fe2N and reduced graphene oxide nanosheets (rGO) composite prepared through a facile annealing process under different atmosphere (NH3/Ar) from Fe3O4 original material. The voids in cubic structure of Fe3N or Fe2N can beneficial to buffer volume changes during lithiation/delithiation processes and provide active sites, and the rGO is helpful to improve electrical conductivity of composites. Moreover, the proportion of Fe3N in the composite is higher than that of Fe2N, indicating that more cubic structure can be released in Fe3N/rGO. Therefore, Fe3N/rGO showed a higher capacity (513 mA h g-1 after 200 cycles at a current density of 0.5 A g-1), better rate performance and more stable cycling performance. This work provides a new direction for the construction of iron-based nitrides with different valence states as anode active materials for LIBs using Fe3O4 as raw material. © 2022, The Authors.
