查询词典 azo

The strain YP-1 could also decolorize another azo dye reactive black 5 of 200mg/L, up to the decolorization of 99.5%.

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。
