- 摘要：从若干种菌源中分离出降解芳香烃类和长链烷烃类化合物的高效菌种,将此菌种与自行设计的新型结构内循环三相流化床相结合应用于处理油制气厂排出的难降解毒性有机废水,分别进行了废水处理动态试验及抗冲击负荷试验,讨论了气水比、pH与COD去除率的关系,分析了酚、氨氮及各类毒性有机物的生物降解情况.结果表明,反应器容积负荷为7.16kg(CODCr)(m3·d),CODCr平均去除率为79.5%,芳烃类化合物的去除率为79.8%,酚类化合物的去除率达948%以上.反应器表现出优良的抗冲击能力与高效的处理能力.
- Abstract：The strains separated from several bacteria sources which can efficiently degrade the aromatic and long chained alkyl organic compounds were coupled with a designed new type structural internal loop three phase fluidized bed to treat the toxic organic wastewater from petroleum manufactory. Dynamic experiments and resist load impact experiments were carried out. The relation between CODCr and pH, gas water ratio were discussed. The biological degradation of phenols, ammonia, azote and other toxic organic compounds were analyzed.The results show that the cubage load was 7 16kg(CODCr)/(m3·d) and 79 5% CODCr was be removed. The bacteria can degrade the aromatic and hydroxybenzene compounds efficiently with the removial rate 79 8% and 94 8% respectively.
