摘要：单原子位点催化剂(SSCs)由于能够产生丰富的活性物质来清除类芬顿体系中的污染物,而显示出广阔的潜力.然而,在高级氧化工艺中,实现金属原子100%的利用率和减少金属浸出以满足环境安全标准是困难的.在此基础上,利用强极化力获得了Co原子含量极低(~0.17%)的催化剂,提高了金属原子利用率,降低了抗生素消除过程中金属浸出的风险.正如预期,该催化剂具有有限的Co位点,伴随着丰富的缺陷和大量从大孔到中孔再到微孔分布的骨架,实现了快速的四环素降解(0.07133 min^(−1))和优异的归一化速率常数(k per-site,2.4726×10^(5) min^(−1) M^(−1)).实验和理论结果均表明,充分暴露具有丰富C-N缺陷的Co位点,可以提高Co活性位点的电子密度,降低过硫酸盐(PDS)的吸附能,从而优化Co原子对PDS活化的利用.该研究为设计高性能、环境友好的水修复用SSCs提供了有价值的见解.

摘要：本研究旨在设计、建造和测试一个中试规模的浮动模块化处理系统,并用以对美国佛罗里达州中部富营养化湖泊中的总磷(TP)进行去除。该处理系统由生物和物理-化学处理模块组成。用多种底物和水生大型植物组合构建了13种不同的中宇宙实验(mesocosm),分别测试了总磷(TP)和正磷(PO_4^(3-))的去除率及潜在的区域去除率。此外本研究对7种吸附介质进行了小型杯罐实验和柱实验,并对3种商业树脂进行了吸附能力的测试。完成这些独立的测试过程后,在佛罗里达中部的一个湖泊中,设计了一个浮岛处理系统(FITS)并运行了8个月。中宇宙实验对磷的平均去除率为40%～50%,平均去除量为5.0 g·m^(–2)·a^(–1)。其中沉水植物(SAV)系统和藻类洗涤器(AGS)效果最好,分别去除了20 mg·m^(–2)·d^(–1)和50 mg·m^(–2)·d^(–1)的磷,它们对磷的平均去除量分别为5.5 g·m^(–2)·a^(–1)和12.0 g·m^(–2)·a^(–1)。在吸附介质中,明矾渣(AR)的性能最佳,接触5 min后,PO_4^(3-)浓度降低了75%左右。在所测试的商品树脂中,PhosX树脂的去除效果最好,在30 min后去除了约40%的磷,60 min后去除了约60%的磷。在基线运行条件下展开实验,FITS对PO_4^(3-)的平均去除率为53%;使用PO_4^(3-)去除率的第50百分位和第90百分位以及FITS的环境足迹进行评价,结果表明系统的去除率分别为56%和86%;区域磷去除率在8.9～16.5 g·m^(–2)·a^(–1)之间。

摘要：Due to the increasingly stringent standards, it is important to assess whether the proposed emission reduction will result in ambient concentrations that meet the standards. The Software for Model Attainment Test-Community Edition （SMAT-CE） is developed for demonstrating attainment of air quality standards of O3 and PM2.5. SMAT-CE improves computational efficiency and provides a number of advanced visualization and analytical functionalities on an integrated GIS platform. SMAT-CE incorporates historical measurements of air quality parameters and simulated air pollutant concentrations under a number of emission inventory scenarios to project the level of compliance to air quality standards in a targeted future year. An application case study of the software based on the U.S. National Ambient Air Quality Standards （NAAQS） shows that SMAT-CE is capable of demonstrating the air quality attainment of annual PM2.5 and 8-hour O3 for a proposed emission control policy.

摘要：In this paper, we propose a new method to estimate the wave height of a specifi c return period based on the Hurst rule and a self-affi ne fractal formula. A detailed description of our proposed model is presented in this paper. We use the proposed model to analyze wave height data recorded along the coast of Chaolian Island from 1963 to 1989. The results show that the performance of our proposed model in estimating design wave heights is superior to traditional models.
