Application of Photo-Fenton,Electro-Fenton,and Photo-Electro-Fenton processes for the treatment of DMSO and DMAC wastewaters

Biological treatment, due to the formation of hazardous chemicals to remove organic compounds such as dimethyl sulfoxide (DMSO) and N, N-dimethylacetamide (DMAC), has limited potential. Advanced oxidation processes (AOPs) are regarded as a viable alternative for treating molecules containing carbon-hydrogen bonds that cannot be broken down by traditional physico-chemical methods. In this investigation, various AOPs such as Photo-Fenton, Electro-Fenton, and Photo-Electro-Fenton processes were studied to treat wastewaters containing DMSO and DMAC. The effects of the operating parameters, including various initial concentrations of DMSO and DMAC, initial pH, reaction time, different concentrations of Fenton’s reagent, power of UV lamp, different concentrations of electrolytes, the distance between electrodes and current intensity, were investigated. The findings of the experiments revealed that a pH of 3 and a reaction time of 120 min were optimal. At 2000 mg L^?1 of DMSO, maximum degradation and the final concentration of TOC were 98.64 % and 256.8 mg L^?1, respectively, by the Electro-Fenton process under the optimal conditions. The Electro-Fenton process was successful in determining the maximum degradation of DMAC (96.31 %) and the final TOC concentration (10.03 mg L^?1) at 250 mg L^?1 of DMAC under optimal conditions. Finally, it can be concluded that the Electro-Fenton process was the best process for the efficient removal of DMSO and DMAC. The second step of the kinetic model follows a pseudo-first-order reaction for 250 and 500 mg L^?1 of pollutants and obeyed a pseudo-second-order kinetic model for concentrations of 1000, 2000 mg L^?1.

基于AOP的系统容错研究

系统容错需要在提供业务逻辑服务的基础上,透明地实现容错的需求．而要透明地实现容错,需要解决冗余资源的确定和管理,失效的检测以及失效的恢复．这些容错需求又将和系统业务逻辑纠缠在一起．所以,如何将系统业务逻辑和容错需求有效地编织在一起,使得系统能以高效、透明的容错能力为用户提供业务逻辑服务,一直是容错系统开发研究所关注的核心问题．AOP的出现,正好为解决容错系统将容错需求与业务逻辑的合理编织问题提供了一种有效的解决途径．本文正是在AOP方法的基础上,利用AOP方法将容错系统的各种业务逻辑定义为核心关注点,而将容错需求定义为不同的横切关注点,进而以不同的方面加以实现,最后以这些方面将业务逻辑有效地编织起来,从而既达成了系统业务逻辑,又满足了透明的容错需求．

Sonochemical synthesis of Ce-TiO2 nanocatalyst and subsequent application for treatment of real textile industry effluent

Treatment of real textile industry effluent using photocatalysis, sonocatalysis, sonophotocatalysis and H₂O₂ assisted sonophotocatalysis have been studied based on the use of Ce-TiO₂ nanocatalyst synthesized using sonochemical co-precipitation method. Characterization studies of the obtained catalyst revealed crystallite size as 1.44 nm with particles having spherical morphology. A shift of the absorption edge to the visible light range was also observed in UV–Vis diffuse reflectance spectra (UV-DRS) analysis. The effects of different operational parameters viz catalyst dose (0.5 g/L-2 g/L), temperature (30 °C-55 °C) and pH (3–12) on the COD reduction were studied. The reduction in the COD was higher at lower pH and the optimum temperature established was 45 °C. It was also elucidated that the required catalyst dose was lesser in combined sonophotocatalysis when compared with individual photocatalysis and sonocatalysis. Combination of processes and addition of oxidants increased the COD reduction with the sonophotocatalytic oxidation combined with H₂O₂ treatment showing the best results for COD reduction (84.75%). The highest reduction in COD for photocatalysis was only 45.09% and for sonocatalysis, it was marginally higher at 58.62%. The highest reduction in COD achieved by sonophotocatalysis was 64.41%. Toxicity tests coupled with Liquid Chromatography Mass Spectrometry (LC-MS) analysis revealed that there were no additional toxic intermediates added to the system during the treatment. Kinetic study allowed establishing that generalized kinetic model fits the experimental results well. Overall, the combined advanced oxidation processes showed better results than the individual processes with higher COD reduction and lower requirement of the catalyst.
