实验对厌氧膜生物反应器(AnMBR)处理活性黑KN-B印染废水进行了探讨.研究了厌氧反应器内活性污泥的驯化培养状况,考察了厌氧反应器与管式超滤膜对印染废水BOD5,COD的去除作用,并对厌氧反应器产气量、出水的碳酸氢盐碱度和VFA进行了分析,通过UV-Vis光谱图分析了AnMBR对活性黑KN-B的脱色效果.结果表明,液流较低的低负荷启动方式使该AnMBR活性污泥的驯化培养顺利进行,厌氧反应器污泥床区域的污泥浓度培养至35 g/L;AnMBR对废水BODs和COD的去除率分别达到90%和85%以上;该厌氧反应器的活性污泥体系和缓冲体系相对稳定,出水的碳酸氢盐碱度和VFA分别在16～18mmol/L与1.0～3.5 mmol/L的范围内波动,pH稳定在7.70～8.00之间;AnMBR对500mg/L的活性黑KN-B废水的脱色率能达到90%以上.
Experiments on the printing and dyeing wastewater containing reactive black 5 treated with anaerobic membrane bioreactor(AnMBR)were discussed.The cultivation and domestication of activated sludge were researched.The effect of anaerobic bioreactor and tubular ultrafiltration membrane on the removal of BOD5 and COD were studied.Gas production, bicarbonate alkalinity and volatile fatly acid(VFA)were analyzed.The decolorization effect of reactive black 5 was analyzed by UV-Vis spectrophotometer.In this study, the changes of MLSS, bicarbonate alkalinity and VFA, pH were in the regular range, along with the loading enhancement during the startup period of AnMBR.The removal rate of BOD5 and COD by AnMBR were above 90 % and 85 %, respectively.Decolorization of reactive black 5 wastewater increased progressively, and up to 90 % finally.The results has shown that low organic loading startup method for AnMBR startup is feasible.
