摘　　要：赤泥沉降分离洗涤工序的任务是对稀释后的溶出矿浆进行液固分离,并将分离所得赤泥进行多次反向洗涤,尽量回收弃赤泥附液中的有用成分.应用在线仪表检测,并实现系统DCS联锁智能优化控制,可以达到稳定工艺技术指标、减少絮凝剂用量、提高洗涤效率、减少弃赤泥附损、提高赤泥处理能力、降低生产成本的目的.The task of the red mud sedimentation, separation washing process is to carry out liquid - solid separation of the diluted dissolution slurry, and carry out multiple reverse washing of the separated red mud to recover the useful components in the red mud solutionas far as possible. The application of on - line instrument detection and intelligent optimization control of DCS interlocking system can achieve the stable technical index, reduce flocculant dos age, improve washing efficiency, reduce red mud damage, improve red mud treatment capacity, and reduce production cost.
