摘　　要：介绍了冷轧酸性废水中和处理法.在该工艺条件下,酸碱中和→曝气→絮凝沉淀→固液分离处理方法与传统的石灰乳一、二级中和法工艺相比,可以降低处理成本和减少沉渣产生量,有较大的推广价值.Introduce the neutralization treating method for cold rlling acid wastewater.Under the conditions of this process,the treating method of acid-base neutralization→aeration→flocculent set-tling→solid-liquid separation is compared with the traditional process of lime milk one-stage and two-stage neutralization,which can reduce treatment cost and sediment production.It has great promotion value.
