| 摘 要： | 采用混凝沉淀法对酒精废水进行深度处理实验及放大应用研究。结果表明,混凝剂种类、投加量、pH值及沉降时间对处理效果都起着重要作用。通过正交实验确定最优化组合,即聚合硫酸铝投加量为60mg／L,pH为8．0左右,沉降时间为90min条件下,废水COD去除率达41．91％;浊度去除率达46．15％;NH3-N去除率达49．61％。混凝沉淀法处理酒精废水可有效减轻后续膜处理工艺负荷,有助于提高回用水质。

| Abstract: | The coagulation precipitation was used to treat the fermentation alcohol wastewater. The influences of coagulation nature, coagulation dosage, pH and sedimentation time were researched. The study showed that PAS was superior to PAC and PFS. The optimum reaction conditions were at pH 8 and 60 mg/L of PAS with 90 min of sedimentation time. Under these conditions, the removal rates of COD, turbidity and NH3-N would reach 41.91%, 46.15% and 49.61%, respectively. The results demonstrated that coagulation precipitation would lighten the burden of following afterpurification system, and help to enhance quality of recycled water. |
