Influence of coexisting substances on the photodegradation behaviors of 17α-ethinylestradiol （EE2） in the UV/H2O2 process

The batch photodegradation reactor was used to investigate the influence of the common coexisting substances in wastewater,such as H+,anions (HCO3-,Cl-and NO3-) and organic compounds (methanol and bisphenol A),on the photodegradation behaviors of EE2 in the UV/H2O2 process.The results indicated that the addition of coexisting substances can influence the photodegradation behaviors of EE2 and it also follows the first-order kinetics.The acidic (pH 2-4) and alkaline (pH 10-12) medium benefit the photodegradation of EE2,but the photodegradation rate constant of EE2 keeps almost constant in the pH value of 4-10.The addition of anions,such as HCO3-,Cl-and NO3-,can inhibit the photodegradation of EE2,and the rate constant has a negative linear relationship with the concentration of the anions.However,the reduction degrees vary with the anions kinds,and the inhibition effect of the three anions is in the order of HCO3->NO3->Cl-.Addition of 5 mg/L methanol and bisphenol A can reduce the photodegradation rate constant of EE2by 84.31% and 72%,respectively.By comparison,the retardant effect of methanol is much more evident.In the studied concentrations range,the photodegradation rate constant of EE2 is the unary quadratic function of the organic compounds concentrations.     

论老庄思想对仙道小说创作的影响

中国古代仙道小说在时间观上秉承了老庄天下万物生于有,有生于无的思想,追求道的无止境才能得到永生;在空间观上,仙道小说中的仙境有的很宏大,可视为道的境界的一种实物载体,有的很微小,蕴藏在壶、枕等器物之中,这是从老庄惯用的逆向思维中汲取了创作灵感。

多年冻土基桩回冻中承载力测试研究

在多年冻土区混凝土灌注桩的施工中,水化热会导致桩周冻土温度升高和部分融化,随着水化热的减少以及向周围冻土传热,桩周土开始慢慢回冻。在此回冻期间,采用自平衡测桩方法对灌注桩的承载力进行了测试。结果表明,经过一个月的回冻时间,基桩即能提供足够的承载力,从而保证下一步施工的正常进行。

原位氮饥饿发酵工艺中梯度补氮对谷氨酰胺合成酶的调控

The effects of uniform and gradient fed nitrogen on glutamine synthetase (GS), glutamate dehydrogenase(GDH) and glutamate synthase ((K)GAT)were investigated in glutamine production by fermentation of Corynebacterium glutamicum NS611 after 3 h of in-situ nitrogen starvation. It was shown that the strain in the later growth phase entered naturally into in-situ nitrogen starvation by controlling the initial concentration of urea and the biomass was slightly decreased. The pH value reached 6.5 again in the culture system, which confirmed the beginning of nitrogen starvation in the culture system. After 3 h nitrogen starvation the activity of GS was increased over two folds and the time of high activity of GS persisted three folds longer in the gradient fed nitrogen system than that in the normal fed batch. The higher activity of GDH was also maintained. The glutamine production increased by 72 % than the original technology of nitrogen starvation and the time of fermentation was shortened by above 12 h.
