铁碳微电解-曝气膜生物反应器处理印染废水
|
摘要
采用铁碳微电解-曝气膜生物反应器(物化-生化)组合工艺对河北省某印染厂的工业废水进行处理。结果表明,铁碳微电解处理废水的优化运行条件,即铁碳质量比3:1、pH为5、曝气反应时间4 h,在此条件下,COD、色度的去除率分别为55%、75%。铁碳微电解处理过后的废水再经曝气膜生物反应器COD负荷为7 g/(m~2·d)、水力停留时间6 h时,处理效果为优。组合工艺对印染废水COD、色度的平均去除率分别为93.8%、91.6%,处理后出水水质满足GB 4287-2012要求。
The wastewater from a dyeing factory in hebei province was treated by the combination process of iron carbon micro-electrolysis and aeration membrane bioreactor(physicochemical and biochemical). In the physical and chemical(iron carbon micro electrolysis) stage, the best operation conditions were: iron/carbon mass ratio was 3:1, pH was 5, aerated reaction time was 4 h. Under this condition, the COD removal rate was 55%, the chroma removal rate was 75%. After that, the aerated membrane bioreactor was optimized using the treated wastewater by iron carbon micro-electrolysis, and the COD load was determined to be 7 g/(m~2·d), and the hydraulic residence time was 6 h. In the optimal processing conditions, the COD removal rate for dyeing wastewater was an average of 93.8%, chroma removal rate was 91.6%. The effluent water quality could meet the standards of GB 4287-2012.
