摘要
应用纳米磁粉磁化细菌生物法处理屠宰废水,结果表明,该工艺能实现磁性生物絮凝泥水混合液的快速有效分离,沉淀时间仅为15min;磁场和磁粉强化了生物新陈代谢作用,增强了污泥活性,提高了废水处理效果,对COD、SS、NH3-N的平均去除率分别可达96%、91%、86%,出水水质优于排放标准。该工艺具有较强的抗冲击负荷能力,应用前景广泛。
A new biological process of bacteria magnetized by magnetic nano-material was used for slaughter-house wastewater treatment. In the process, the mixed liquid of magnetic and flocculated sludge can be separated quickly and effectively, with sedimentation time only 15 min. Magnetic field and magnetic material enhance the metabolism of organism, augment the sludge activity, and improve the wastewater treatment effect, and the removal rate for COD, SS, and NH_3-N is averaged at 96%, 91%, and 86% respectively and the effluent quality surpasses the discharge standard. The process has higher capacity in resistance to shock loading and will be widely applied in future.
