| 1 | A Floating Island Treatment System for the Removal of Phosphorus from Surface Waters显示文摘本研究旨在设计、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。 | Mark T.

| 2 | Optimizing beam transport in rapidly compressing beams on the neutralized drift compression experiment-II显示文摘The Neutralized Drift Compression Experiment-II(NDCX-II)is an induction linac that generates intense pulses of 1.2 MeV helium ions for heating matter to extreme conditions.Here,we present recent results on optimizing beam transport.The NDCX-II beamline includes a 1-m-long drift section downstream of the last transport solenoid,which is filled with charge-neutralizing plasma that enables rapid longitudinal compression of an intense ion beam against space-charge forces.The transport section on NDCX-II consists of 28 solenoids.Finding optimal field settings for a group of solenoids requires knowledge of the envelope parameters of the beam.Imaging the beam on the scintillator gives the radius of the beam,but the envelope angle is not measured directly.We demonstrate how the parameters of the beam envelope(radius,envelop angle,and emittance)can be reconstructed from a series of images taken by varying the B-field strengths of a solenoid upstream of the scintillator.We use this technique to evaluate emittance at several points in the NDCX-II beamline and for optimizing the trajectory of the beam at the entry of the plasma-filled drift section. | Anton D.Stepanov John J.Barnard Alex Friedman Erik P.Gilson David P.Grote Qing Ji Igor D.Kaganovich Arun Persaud Peter A.Seidl Thomas Schenkel | 2018 | Matter and Radiation at Extremes2018，3，2： | 2 |
