摘要:

采用UV 氧化+膜生物反应器(MBR)组合工艺处理模拟印染废水,考察了该工艺的处理效果及生物强化作用对MBR 工艺的影响。MBR 实验条件为:水温25 ℃,pH=6,水力停留时间10 h,溶解氧3~5 mg/L,运行时间60 d,强化菌种按质量分数0.5%投入到MBR。实验结果表明, UV 氧化大大降低了废水的毒性,组合工艺对TOC 的总平均去除率达到89%,出水水质良好。此外,生物强化使活性污泥具有更好的生理活性和抗冲击负荷能力。

Abstract:

The membrane bioreactor (MBR) coupled with UV oxidation system has been used for treating simulated dyeing wastewater. The effects of the treatment effectivenss and bio-augmentation capacity on MBR process have been studied. MBR system is to be operated under the conditions of T=25 ℃,pH=6,HRT=10 h and DO=3~5 mg/L,running time 60 d,and the augmented strains are dosed into MBR in a certain proportion of 0.5%. The results illustrate that the UV oxidation lowers the toxicity of the wastewater greatly,and the total average removal rate of TOC reaches 89%. The effluent water quality is pretty good. Moreover,bio-augmentation makes the activated sludge take on better physiological activity and anti-shock loading capability.

Key words: UV oxidation, membrane bioreactor, dyeing wastewater, bio-augmentation
