摘　　要：现阶段,某木薯酒精加工企业运行过程中,木薯酒精废水经原工艺处理后,化学需氧量(COD_(Cr))及总磷(TP)指标排放不稳定,有必要进行工艺改造研究。研究表明,深度处理工艺增加"酸析絮凝气浮"工序,能有效提高COD_(Cr)及TP的去除率。工艺优化后,深度处理工艺对SBR池出水COD_(Cr)、TP的去除率分别提升至85.34%、97.69%,而且实现了废水稳定达标排放。At this stage,during the operation of a cassava alcohol processing enterprise,after cassava alcohol wastewater is treated by the original process,the discharge of chemical oxygen demand (COD_(Cr)) and total phosphorus (TP) indicators is unstable,and it is necessary to conduct process transformation research.Studies have shown that the addition of "acid flocculation and air flotation" to the advanced treatment process can effectively improve the removal rate of COD_(Cr)and TP.After the optimization of the process,the removal rate of COD_(Cr)and TP of the effluent from the SBR pool is increased to 85.34% and 97.69% by the advanced treatment process,and the discharge of wastewater is stable and up to standard.
