摘要：
A novel 3D α-FeOOH@MoS(2)/rGO nanocomposite was successfully fabricated by a simple in situ hydrothermal method. It is a highly efficient heterogeneous catalyst in activation of peroxymonosulfate (PMS) for rapid degradation of rhodamine B (RhB), with 99.9% of RhB removed within 20min. The introduction of rGO contributes to uniform dispersion and sufficient contact of α-FeOOH and MoS(2) nanosheets. Highly active Mo(IV) enhances the reduction of Fe(III), improves Fe(III)/Fe(II) conversion and promotes the generation of O(2)1, which ensures an improved catalytic activity. MoS(2)/rGO hybrid can effectively solve the problem of material reunion and make α-FeOOH exhibit excellent catalytic performance. The α-FeOOH@MoS(2)-rGO/PMS system is a co-catalytic system based on the active components of α-FeOOH and MoS(2). The main reactive oxygen species in the α-FeOOH@MoS(2)-rGO/PMS system are O(2)1, SO(4)(.-) and ⋅O(2)(-), which contribute to a high reactivity over a wide range of pH (5-9). Besides, this system is highly resistant to anions (Cl(-), SO(4)(2-)) and natural organic matter (humic acid), and can be widely used for degradation of common organic pollutants. The α-FeOOH@MoS(2)/rGO is a promising Fenton-like catalyst for refractory organic wastewater treatment.

摘要：
The discharge of phosphorus in water has led to the problems of eutrophication and waste of phosphorus resources. Here, calcium silicate hydrate supported on hydrochar derived from microwave-assisted hydrothermal treatment (w-CH/CSH) was developed for phosphate removal. The characterizations of w-CH/CSH were examined through scan-ning electron microscope, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectrometer, and specific surface area analyzer. Batch adsorption experiments were conducted to identify the adsorption characteristics of phosphate onto w-HC/CSH. Results showed that the best w-HC/CSH adsorbent was successfully prepared. The CSH was uniformly distributed on the hydrochar surface and the specific surface area (SSABET) of w-HC/CSH increased to 98.76 m2/g. The phosphate adsorption was governed by chemisorption on heterogeneous surfaces and could be better fitted by the pseudo -second-order and Freundlich model. The film diffusion and intraparticle diffusion were the rate-limiting process of phosphate adsorption. The underlying mechanisms were mainly attributable to the surface microprecipitation including Ca3(PO4)2, Ca8H2(PO4)6, Ca(H2PO4)2, CaHPO4 and Ca5(PO4)3Cl, and the ligand exchange with the CaCO3 and oxygen-containing functional groups.(c) 2022 The Author(s).

摘要：
This study prepared iron-manganese oxide-modified biochar (FM-BC) by impregnating rice straw biochar (BC) with a mixed solution of ferric nitrate and potassium permanganate. The effects of pH, FM-BC dosage, interference of coexisting ions, adsorption time, incipient Pb(II) concentration, and temperature on the adsorption of Pb(II) by FM-BC were investigated. Moreover, the Pb(II) adsorption mechanism of FM-BC was analyzed using a series of characterization techniques. The results showed that the Fe-Mn oxide composite modification significantly promoted the physical and chemical functions of the biochar surface and the adsorption capacity of Pb(II). The specific surface area of FM-BC was 18.20 times larger than that of BC, and the maximum Pb(II) adsorption capacity reached 165.88 mg/g. Adsorption kinetic tests showed that the adsorption of Pb(II) by FM-BC was based on the pseudo-second-order kinetic model, which indicated that the adsorption process was mainly governed by chemical adsorption. The isothermal adsorption of Pb(II) by FM-BC conformed to the Langmuir model, indicating that the adsorption process was spontaneous and endothermic. Characterization analyses (Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy) showed that the adsorption mechanism of Pb(II) by FM-BC was mainly via electrostatic adsorption, chemical precipitation, complexation, ion exchange, and the transformation of Mn2O3 into MnO2. Therefore, FM-BC is a promising adsorbent for Pb(II) removal from wastewater.
摘要：
Abstract: The COVID-19 epidemic has changed people’s life manners and also impacted the thinking ways of college students greatly. Nowadays, people have a new understanding of ecological civilization. Students majoring in environmental engineering, environmental science and other related majors with professional knowledge of environmental remediation have more ability to make suggestions for environmental protection. When teaching professional knowledge, vivid examples of the epidemic should be highlighted, and the ideological and political elements such as patriotism, social responsibility and benevolence should also be integrated, so that the specialized knowledge would be more valuable. “Environmental engineering microbiology” was taken as an example of the professional basic course in environment engineering and the related majors in this paper. In order to achieve better teaching effect and moral cultivation, digging ideological education resources, strengthening political education in practice course, highlighting the typical cases and paying attention to students’ feedback were discussed.#@#@#摘要: 新冠疫情改变了人们的生活方式，也给当今大学生的思想带来了极大的冲击。现如今，人们对于生态文明教育有了新的思考和认识。有着专业环保知识的环境工程、环境科学等相关专业学生对于环境保护有着更多建言献策的能力。在课程专业知识传授中突显此次疫情中的鲜活典型，融入家国情怀、社会责任、仁爱之心等思政元素，将使得知识传播在价值引领下大放异彩。本文以《环境工程微生物学》这门环境类专业基础课程为例，从挖掘专业知识中蕴含的思政教育资源、强化实践课程中体现的思政教育价值、以案例为载体开展启发式教学和注重学生反馈、避开“课程思政”误区四个方面进行探讨，以期达到更好的教书育人效果。

摘要：
Characterizing the microbial communities associated with soil-borne disease incidence is a key approach in understanding the potential role of microbes in protecting crops from pathogens. In this study, we compared the soil properties and microbial composition of the rhizosphere soil and roots of healthy and bacterial wilt-infected tobacco plants to assess their potential influence on plant health. Our results revealed that the relative abundance of pathogens was higher in diseased plants than in healthy plants. Moreover, compared with healthy plants, there was a significantly higher microbial alpha diversity in the roots and rhizosphere soil of diseased plants. In addition, we detected a lower abundance of certain plant microbiota, including species in the genera Penicillium, Trichoderma, and Burkholderia in the rhizosphere of diseased plants, which were found to be significantly negatively associated with the relative abundance of Ralstonia. Indeed, compared with healthy plants, the co-occurrence networks of diseased plants included a larger number of associations linked to plant health. Furthermore, structural equation modeling revealed that these specific microbes were correlated with disease suppression, thereby implying that they may play important roles in maintaining plant health. In conclusion, our findings provide important insights into the relationships between soil-borne disease incidence and changes in the belowground microbial community. These findings will serve as a basis for further research investigating the use of specific plant-associated genera to inhibit soil-borne diseases.

摘要：
Sulfhydryl magnetic biological bamboo charcoal nanocomposite (BBC@nFe-SH) was prepared by chemical co-precipitation method for the robust capture of As(III) from aqueous solutions. The novel BBC@nFe-SH shows favorable magnetic field strength (83376 A/m), which enables BBC@nFe-SH to be quickly recovered from aqueous solution. The maximum As(III) adsorption capacity is as high as 98.63 mg/g at pH 5.0 and 40 °C, reaching reaction equilibrium within 120 min. Various characterizations (e.g., SEM, FTIR, VSM and XPS) suggest that As(III) prefers to coordinate with surface oxygen groups bonded to the surface. BBC@nFe-SH displayed high stability and recyclability throughout the removal process, which could be easily activated by 1 mol/L NaOH after usage. Thus, the novel BBC@nFe-SH has promising applications for As(III) treatment.
