    • 摘要: 糖蜜酒精废液COD高、黏度高、处理难度大,较为理想的多效蒸发浓缩焚烧处理技术依然有较大的传热阻力.对此,本文采用螺纹管替代光滑管来强化传热,在近似实际工况下,光滑管作参照,测试不同管参数螺纹管的传热性能.实验证实,螺纹管可显著地强化高黏度、低Re时糖蜜酒精废液的传热.本文还采用Fluent软件对过程进行数值模拟,准确直观地再现了螺纹管传热强化的微观现象,解释了螺纹管内凸肋和外凹槽对管内外流体的传热强化机理.

    • 摘要: Red mud was ifrstly acidiifed byH2SO4 and molasses alcohol wastewater, and then calcined to obtain a red mud-based heterogeneous catalyst, i.e. SMA-CA/red mud. The SMA-CA/red mud was characterized by XRD, EDS and N2 adsorption-desorption, and then was used for degradation of orangeⅡ in Fenton-like process. The characterization results showed that after the acidiifcation and calcination, α-FeOOH in red mud was changed into α-Fe2O3 of SMA-CA/red mud, and the alkaline compounds in SMA-CA/red mud were effectively reduced. Compared with that of red mud-based heterogeneous catalyst which was acidiifed without molasses alcohol wastewater, the pore diameter and the macropore distribution of SMA-CA/red mud all increased. The experimental results showed that the removal rate of orangeⅡ reached 86.79% under the conditions of initial concentration of orangeⅡ40 mg/L, initial concentration of H2O2 50 mmol/L, solution pH value 3, reaction time 6 h. The degradation reaction accorded with the ifrst-order kinetics model.%采用糖蜜酒精废液协同H2SO4对赤泥进行酸化改性,再经高温焙烧处理,得到赤泥基非均相催化剂(SMA-CA/赤泥),通过XRD、EDS、N2吸附脱附技术对SMA-CA/赤泥进行了表征,并将其用于金橙Ⅱ的类Fenton催化降解。表征结果显示:经酸化和焙烧,赤泥中的α-FeOOH转变为SMA-CA/赤泥中的α-Fe2O3,且酸化改性使得SMA-CA/赤泥碱含量显著降低;与未添加糖蜜酒精废液酸化改性的赤泥基非均相催化剂相比, SMA-CA/赤泥的孔径增大,大孔分布提高。实验结果表明:在初始溶液pH值为3、H2O2投加量50 mmol/L、金橙Ⅱ质量浓度40 mg/L、反应时间6 h的条件下,金橙Ⅱ去除率达到86.79%;该催化降解过程符合一级动力学模型。

    • 摘要: Dominant bacterial strains have been screened out from UASB reactor granular sludge which was used in the treatment of molasses alcohol wastewater,and the ecological niche,metabolic products,and degradation capacity of dominant bacteria are studied. The results show that the compound florae ,which consist of dominant strains ,have wide ecological niches. In different niches ,compound florae have corresponding dominant strains.
