折流板厌氧反应器具有运行稳定、抗冲击负荷能力强、处理效率高等优点.采用ABR水解处理印染废水,在HRT=11 h的条件下对ABR进行中试研究,测定了ABR对COD、色度、SS等的去除效果.结果表明,ABR对COD的去除效果明显,同时经其处理后B/C有一定程度增加,后续经好氧处理后最终出水COD可达100 mg/L左右. 相似文献

采用小试规模的厌氧折流板反应器(Anaerobic Baffled Reactor,ABR)在常温下处理人工模拟废水,初始CODCr浓度为300mg/L,依次递增300mg/L以增加容积负荷,直至CODCr浓度为3000mg/L研究其运行状况。结果表明:好氧污泥与厌氧污泥颗粒混合接种可以使ABR反应器成功启动;处理CODCr浓度为300-600mg/L的废水时,出水可达到国家综合排放二级标准,处理CODCr浓度为2100-2700mg/L废水时,最高去除率可稳定在90%左右,接近二级排放标准。因此,利用ABR处理低浓度城市生活废水或作为较高浓度城市生活废水的前处理工艺,具有一定的可行性。 相似文献

利用取自ABR反应器的厌氧颗粒污泥,以葡萄糖为共基质,测定了不同浓度4-氯酚对厌氧污泥产甲烷微生物的影响以及活性恢复情况。试验结果表明:4-氯酚对厌氧颗粒污泥产甲烷活性具有较强的抑制作用,当4-氯酚的质量浓度为300 mg/L时,抑制作用最小;并且随着4-氯酚浓度的继续提高,厌氧颗粒污泥的产甲烷活性显著下降。当4-氯酚的质量浓度为400、500、600 mg/L时,相应的抑制程度为31%、68%、54%。4-氯酚对厌氧生物降解葡萄糖反应的抑制作用,在低浓度时发生在反应后期,高浓度时发生在反应初期。同时在恢复试验中不同浓度的4-氯酚对产甲烷的抑制作用仍存在,但有所降低。 相似文献

Ozone-water mass transfer was investigated using an oscillatory baffled reactor (OBR) operated as a semi-batch and as a co-current up flow continuous reactor. The effects of input ozone concentration, input gas and water flow rates, and oscillation conditions on gas hold up, volumetric mass transfer coefficient and mass transfer efficiency were determined. The same reactor was operated as a baffled column (without oscillation) and as a bubble column to assess the effect of the reactor arrangement on the mass transfer. The results show that the OBR was 5 and 3 times more efficient for ozone-water mass transfer than the baffled and bubble columns, respectively. The enhancement obtained with OBR over the baffled column reactor was found to decrease with gas flow rate due to changes in bubble flow pattern from homogenous to heterogeneous. Under continuous flow conditions, the performance of the baffled reactor and the OBR were found to be twice efficient for ozone-water mass transfer than when operating under semi-batch conditions. The mass transfer effeciency (MTE) was found to increase from 57% using the baffled reactor to 92% with OBR under continuous flow at water and gas superficial velocities of 0.3 and 3.4 cm s−1, respectively. 相似文献
