摘要
以聚合氯化铝为絮凝剂,采用电气浮技术处理印染废水,研究了电气浮各工艺条件对COD去除效果的影响。结果表明,在絮凝剂投加量为40 mg/L、电流强度1 A、反应时间40 min、极板间距1 cm、pH值为7的情况下,对印染废水COD有较好的去除效果,为后续处理提供了基础。
Taking polymer alumina as flocculent,the flocculation/electro-flotation technology was employed to treat dyeing wastewater.The results indicated that a successful removal effect of COD was obtained with PAC of 40 mg/L,current intensity of 1 A,reaction time of 40 min,plate spacing of 1 cm,pH value of 7.The valuable reference for the treatment of the dyeing wastewater was provided.
