An anaerobic-aerobic intermittent CSTR process was used to decolorize mixed dye with E. coli NO3 strain at a hydraulic retention time of 32, 18, and 10 h. The color-removal efficiency was around 70 ~ 80%. Under steady operation for over 117 h, the total decolorization was 10900, 18200, and 7590 for HRT=32, 18, and 10 h, respectively. After repeated operation cycles, the decolorization rate of E. coli NO3 was always higher than the original cycle. This may be attributed to the acclimation effect since the E. coli NO3 cells were repeatedly exposed to the azo dye.

NO3於HRT = 10、18、32小时之条件下进行厌氧-好氧间歇式CSTR生物反应器褪色操作,褪色率可以达到7080﹪左右;在约117小时的稳定褪色操作下,总褪色量分别为10900、18200及7590,这显示NO3在长时间之间歇式CSTR褪色操作下,不但稳定且具有优异之褪色能力;若将一组好氧、厌氧步骤视为一个循环去探讨褪色率之变化,则可观察到随著循环次数增加其褪色率逐次上升,之后则明显下降,这与摇瓶重复批次实验相似之结果,也可以解释为驯养效应所导致。

Results: Pericoronitis was a complex odontogenic infection with aerobic bacteria and anaerobic bacteria.

结果:冠周炎为需氧菌和厌氧菌的混合感染,药物敏感试验显示氯林可霉素对需氧菌和厌氧菌均有显著的抑制作用。

The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.

结果表明,在Fe^0-厌氧微生物体系中,Fe^0投加量和pH值均存在最适宜值,当两者分别控制在400mg/L和7,染料初始浓度和反应时间分别为100mg/L和68h时,该体系脱色率可达到90%以上;与相同反应条件下的纯Fe^0、纯厌氧微生物体系相比,该体系的脱色率提高近40%根据紫外可见光谱分析,Fe^0可有效促进厌氧微生物对X-BR及其中间产物的降解,实现完全脱色。
