流动电容去离子(Flow electrode capacitive deionization,FCDI)技术是一种用于污水处理的高效脱盐技术。由于流动电极浆内活性物质的导电性低,抑制了FCDI的电流效率和脱盐性能。因此,通过引入生物碳材料如碳化细菌纤维素(Carbonized bacterial cellulose,CBC)、碳化几丁质(Carbonized chitin,CCH)和碳化秸秆(Carbonized straw,CSW)作为导电剂加入流动电极,以提高活性材料[活性炭(AC)]的利用率。研究发现:在施加电压为1.8 V和盐水浓度范围为1.01~35.00 g/L的条件下,质量分数为5%的AC中加入质量分数为0.25%的CBC的除盐率为1.26~5.92 mmol·L^(-1)·(m^(2)·s)^(-1),高于质量分数为5%的AC的除盐率[0.09~2.58 mmol·L^(-1)·(m^(2)·s)^(-1)]。电化学和物理表征分析进一步表明,与引入球形炭黑颗粒(Carbon black,CB)相比,CBC可以更有效地在流动电极中形成相互连接的导电网络,从而提高流动电极的整体导电性。最后,所建立的FCDI系统在印染尾水脱盐中显示出良好的效果和应用潜力。

Fe3O4 nano-whiskers were synthesized via ultrasonic-aided reduction of FeCl2.4H2O with N2H4-H2O in concentrated NaOH solution. Phase identification and morphology observation were conducted by X-ray diffraction （XRD） analysis, transmission electron microscopy （TEM） and field emission scanning electron microscopy （FE-SEM）. Face scanning energy dispersive spectrum （face scanning EDS） and twodimensional fast Fourier transform （2DFFF） for element distribution were carried out for confirming composition homogeneity. From XRD and TEIVI, the synthesized Fe304 nano-whiskers are of cubic phase with average dimension of 20 nm~ 200 nm （average aspect ratio of 10）. FE-SEM shows that the nanowhiskers without dispersion are interconnected into a network at a scale of 20μm. 2DFFT of the distribution of Fe and O from face scanning EDS confirms the composition homogeneity of the synthesized Fe3O4. Hydrazine hydrate determines the formation of the nano-whiskers, while the possible mechanism is the preferred growth along certain orientation with the aid of ultrasonic treatment.

In this paper, the dynamic response of a marine riser under excitation of internal waves is studied. With the linear approximation, the governing equation of internal waves is given. Based on the rigid-lid boundary condition assumption, the equation is solved by Thompson-Haskell method. Thus the velocity field of internal waves is obtained by the continuity equation. Combined with the modified Morison formula, using finite element method, the motion equation of riser is solved in time domain with Newmark-β method. The computation programs are compiled to solve the differential equations in time domain. Then we get the numerical results, including riser displacement and transfiguration. It is observed that the internal wave will result in circular shear flow, and the first two modes have a dominant effect on dynamic response of the marine riser. In the high mode, the response diminishes rapidly. In different modes of internal waves, the deformation of riser has different shapes, and the location of maximum displacement shifts. Studies on wave parameters indicate that the wave amplitude plays a considerable role in response displacement of riser, while the wave frequency contributes little. Nevertheless, the internal waves of high wave frequency will lead to a high-frequency oscillation of riser; it possibly gives rise to fatigue crack extension and partial fatigue failure.
