摘要：
In this work, the thermo-sensitive materials N-isopropylacrylamide (NIPAM) and acrylic acid (AA) were crosslinked with carboxymethyl cellulose (CMC) (CMC/P (NIPAM-co-AA) via a free radical polymerization method for the removal of U(VI) from aqueous solution. The L16 (45) orthogonal experiments were designed for the optimization of the synthesis condition. The chemical structures of the crosslinking hydrogel were confirmed by FTIR spectroscopy. The microstructural analyses were conducted though scanning electron microscopy (SEM) to show the pore structure of the hydrogel. The adsorption performance of the CMC/P (NIPAM-co-AA) hydrogel for the uptake of U(VI) from simulated wastewater was also investigated. The adsorption reached equilibrium within 1 h. Under the reaction of pH = 6 and a temperature of 298 K, an initial concentration of U(VI) of 5 mg L-1, and 10 mg of the CMC/P(NIPAM-co-AA) hydrogel, the maximum adsorption capacity was 14.69 mg g-1. The kinetics fitted perfectly with the pseudo-second-order model, and the isotherms for the composite hydrogel adsorption of U(VI) was in accordance with the Langmuir model. The chemical modification confirmed that the acylamino group played an important role in uranium adsorption. The desorption and reusability study revealed that the resolution rate was still available at approximately 77.74% after five alternate heating cycles at 20 and 50 °C of adsorption-desorption. © 2020 by the authors.

摘要：
The microbial characteristics and bacterial communities of sediment sludge upon different concentrations of exposure to uranium were investigated by high solution transmission electron microscopy (HRTEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and high-throughput sequencing. After exposure to initial uranium concentrations of 10–50 μM for 24 h in synthetic wastewater, the removal efficiencies of uranium reached 80.7%–96.5%. The spherical and short rod bacteria were dominant in the sludge exposed to uranium. HRTEM-EDS and XPS analyses indicated that reduction and adsorption were the main mechanisms for uranium removal. Short-term exposure to low concentrations of uranium resulted in a decrease in bacterial richness but an increase in diversity. A dramatic change in the composition and abundances of the bacterial community were present in the sediment sludge exposed to uranium. The highest removal efficiency was identified in the sediment sludge exposed to 30 μM uranium, and the dominant bacteria included Acinetobacter (44.9%), Klebsiella (20.0%), Proteiniclasticum (6.7%), Enterobacteriaceae (6.6%), Desulfovibrio (4.4%), Porphyromonadaceae (4.1%), Comamonas (2.4%) and Sedimentibacter (2.3%). By comparison to the inoculum sediment sludge, exposure to uranium caused a substantial difference in the majority of bacterial abundance. © 2020 Elsevier Ltd

摘要：
《指南》提出了试算法与模型模拟法对海绵城市专项规划中的年径流总量控制率这一刚性指标进行分解落实,但由于《指南》尚处于试行阶段未对如何运用模型模拟法进行指标分解作出解答,且以SWMM为典型代表的水文水力模拟研究也较少以此作为切入点展开探讨。因此,研究借助SWMM模型探索出一条具有普遍适用性的指标分解途径,通过现状评估、刚性指标分解及引导性指标分解三个阶段完成年径流总量管控指标的分解,并借助案例对分解赋值方法进行详尽阐述,愿能为今后海绵城市专项规划的编制工作提供些许参考。

摘要：
With the acceleration of the urbanization process, and the increase of the impervious surface area, the problems of urban waterlogging are becoming more and more serious. How to effectively reduce the frequency of urban rain and flooding and its impact and destruction has become a major problem in urban construction. This paper selects the area around Guangming Phoenix New City Park in Guangming District, Shenzhen, constructs regional rainfall runoff model by SWMM model, and simulates the operation of the existing drainage network and the degree of waterlogging under six types of rainstorm return period of 1a, 3a, 5a, 10a, 20a, and 50a. Consequently, on this basis, four kinds of low impact development (LID) measures including separating the placement of bioretention cells, green roof, permeable paving, and rain barrels, and combined arrangement as the fifth schemes, are used to stimulate the reduction of the regional total runoff and total peak flow. By the comparison, in the current state of study, LID combination has the best effect in reducing the total runoff, followed by the bioretention cells, permeable paving, and rain barrels; green roof is the worst. In terms of reducing total peak flow and delaying the time of peak flow, LID combination is the best, followed by bioretention cells, permeable paving, and green roof; the worst is rain barrels. In basis of this to consider the problem of combining low impact development measures with the sponge city special plan. In the future, it is expected to inspire the construction of sponge cities in south coastal cities, especially the low impact development measures.

摘要：
Sulfate-reducing granular sludge was used for uranium-contaminated wastewater treatment and the responsible microbial community was analyzed. Four feedings, with 6 days for every feeding and 20 mg/L initial uranium, were provided at 27.5 (±2.5) oC. After the four feedings, a uranium removal efficiency of 94% was obtained. Environmental scanning electron microscopy (ESEM) showed that short rod bacteria were the dominant microorganisms in the granular sludge. X-ray energy dispersive spectroscopy (EDS) confirmed the presence of uranium on the granular surface. High-throughput sequencing was carried out for analyzing the bacterial diversity and community structure. The total data set comprised 8,290 high quality sequences, which could be divided into 605 operational taxonomic units (OTUs). The library coverage was 0.96 and the alpha diversity indices of ACE, Chao1, Shannon and Simpson were 2,255.40, 1,346.12, 4.03 and 0.05, respectively. There were 13 bacterial genera present with a ratio of more than 1% of the total 124 genera, among which Desulfovibrio (16.48%), Clostridium IV (9.29%), Bacteroides (3.46%) and Citrobacter (1.41%) were assumed as the functional bacteria, with a cumulative proportion of 30.64% of the total bacterial population. The results provide insights into the bacterial community of sulfate-reducing granular sludge exposed to high concentrations of uranium (20 mg/L). © IWA Publishing 2019

摘要：
Polyethyleneimine (PEI)/graphene oxide (GO) was synthesized through a self-assembly method with the formation of the amide group –CONH– between –NH 2 on PEI and –COOH on GO. The formation was confirmed by Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The oxygen- and nitrogen-containing functional groups of PEI/GO were involved in the adsorption of U(VI), as determined under the FT-IR and XPS analyses of PEI/GO and U(VI)-adsorbed PEI/GO. The pH, contact times, and initial concentration, which are the factors influencing the removal of U(VI), were investigated. The adsorption of U(VI) onto PEI/GO was fitted well with the pseudo-second-order kinetic model and Langmuir isotherm model. The maximum sorption capacities of U(VI) on PEI/GO (145.14 mg·g −1 ) at pH = 7 and T = 303 K were higher than that of U(VI) on GO (94.61 mg·g −1 ). This study provides a novel and simple method for synthesizing GO derivatives with efficient adsorption performances of U(VI) from aqueous solution. © 2018

摘要：
The bacterial community of an anaerobic granular sludge associated with uranium depletion was investigated following its exposure to uranium under different initial pH conditions (pH 4.5, 5.5, and 6.5). The highest uranium removal efficiency (98.1%) was obtained for the sample with an initial pH of 6.5, which also supported the highest bacterial community richness and diversity. Venn diagrams visualized the decrease in the number of genera present in both the inoculum and the uranium-exposed biomass as the initial pH decreased from 6.5 to 4.5. Compared with the inoculum, a significant increase in the abundances of the phyla Chloroflexi and Proteobacteria was observed following uranium exposure. At initial pH conditions of 6.5 to 4.5, the proportions of the taxa Anaerolineaceae, Chryseobacterium, Acinetobacter, Pseudomonas, and Sulfurovum increased significantly, likely contributing to the observed uranium removal. Uranium exposure induced a greater level of dynamic diversification of bacterial abundances than did the initial pH difference. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

摘要：
各城市5%步长年径流总量控制率与设计降雨量无法完全满足海绵城市专项规划编制及相关科研工作的需求。因此,本研究以萍乡市莲花县为例借助线性插值法对1%步长年径流总量控制率与设计降雨量进行估算,并将10958条降雨数据统计得出的实际值与估算值做误差分析,结果表明,该方法具有准确率高、快速、简便且无需重新统计萍乡市近30年日值降雨数据等优点,具有较好的可推广性。

摘要：
Polyaniline/oxidation etching g-C3N4 composites (PANI/OCN) were synthesized through an oxidative polymerization method and applied to remove U(VI)from aqueous solution as an adsorbent. The PANI/OCN showed high maximum adsorption capacity (qm = 312.5 mg g−1, T = 293 K, pH = 5), which was higher than OCN and many other adsorbents,and extremely fast adsorption rate (in 10 min). The adsorption process was fitted well to the pseudo-second-order kinetic equation and Langmuir model. Adsorption–desorption experiment revealed the good reusability of PANI/OCN. This study provides a potential composite with excellent performance for U(VI) removal. © 2019, Akadémiai Kiadó, Budapest, Hungary.

摘要：
以热灭活的植物乳杆菌为生物吸附剂,探讨了吸附U(VI)的影响,并采用扫描电镜-能谱、红外光谱等手段研究了U(VI)的吸附机理。结果表明,植物乳杆菌对U(VI)具有良好的吸附效果。在pH为6.0,温度30℃,灭活乳杆菌投加量为120 mg/L,初始U(VI)的质量浓度为10 mg/L时,植物乳杆菌对U(VI)的去除率可达94.28%,吸附平衡时间为4 h。吸附过程较好符合准2级动力学吸附模型和Freundlich模型。经过灭活的植物乳杆菌的菌体比表面积增加,能更好的吸附U(VI),配位络合是菌体吸附U(VI)的主要机理,参与吸附的官能团有细胞表面多糖与蛋白质羟基、蛋白质酰胺基、羧基与磷酸酯基等。此外菌体表面的静电作用也是吸附的方式之一。

摘要：
利用土著洋葱假单胞菌进行试验,探讨了其对低浓度含铀废水处理的性能。结果表明: ρ[U(Ⅵ)]为10 mg/L, pH为6.0,温度为30 ℃时,菌体对U(Ⅵ)的最大平衡吸附量可达到160.4 mg/g。重金属离子(Cu~(2+)、Pb~(2+)、Zn~(2+)等)对U(Ⅵ)去除存在较大影响。重金属离子浓度为100 mg/L时,Cu~(2+)、Pb~(2+)对菌体去除U(Ⅵ)有明显的抑制作用,而Zn~(2+)的影响微弱。采用SEM-EDX、XRD、FTIR表征分析,阐明铀-细菌相互作用的反应机理。结果表明: U(Ⅵ)以絮状磷酸铀化合物沉积在细胞表面,羟基、羧基和磷酸盐基团促进了U(Ⅵ)的生物沉积。土著洋葱假单胞菌可以耐受U(Ⅵ)和其他重金属毒性,可与U(Ⅵ)发生矿化反应,可在低浓度含铀废水处理方面发挥重要作用。
