摘要:在含有表面活性剂的废水中进行微孔曝气,形成稳定的泡沫层,泡沫层与固定化微生物接触,使表面活性剂得到降解、研究结果表明泡沫层生化反应有助于优势微生物的富集,表面活性剂降解速度从21mg(L·h)提高到35mg(L·h);表面活性剂的去除率从71%提高到95%,而且这种方法可以解决含表面活性剂废水处理过程中泡沫四处外溢的现象。
In this study, the wastewater containing surfactants is aerated to form the foam which contacts the immobilizde bacteria bed so as to degrade the surfactants. The results show that bio-reaction in foam could help the superior bacteria to accumulate. The degradation velocity of surfactants in the foam is rised to 35 mg/(L.h) from 21 mg/(L·h) and the removal rate of surfactants is rised to 95% from 71%. Moreover in this method no foam will overflow from the apparatus.
