摘要
利用IAL-CHS反应器分别吸附单一的微生物Achromobactersp.来降解2,4-二氯酚(2,4-DCP)和吸附复合微生物菌群来处理啤酒废水.通过比较试验表明,单一的微生物和复合微生物菌群均能很容易地在蜂窝陶瓷载体的表面上形成生物膜,并表现出较高的生物活性.在连续降解2,4-DCP时,反应器稳定运行之后,2,4-DCP的去除率达到98%.连续流处理啤酒废水时,在水力停留时间为7h条件下,随着进水的COD浓度逐渐增加,其COD去除率达到95.5%.有机物负荷也逐渐增高,达到3.52kgCOD/(m3·d).
Internal airlift loop with ceramic honeycomb support (IAL-CHS) reactor was respectively used for degradation of 2,4-DCP by Achromobacter sp. and treatment of brewery wastewater by complex microorganisms. Biofilm was all easily formed on surface of ceramic support by strain of Achromobacter sp. and complex microorganisms and presented higher biological activity according to the comparative experiments. When 2,4-DCP was degraded continuously during stabilization, the 2,4-DCP removal rate was 98% under continuous operation and hydraulic resident time (HRT) of 6 hours. The COD of brewery wastewater was removed about 95.5% with increasing of influent under HRT of 7 hours during continuous treatment, and its organism loading was 3.52kg COD/(m3 ·d).
