铅锌选矿废水处理自控系统设计及应用

针对铅锌矿选厂人工简单处理废水带来的水质差、指标不稳定、无法连续回用等问题,设计了一种高效的选矿废水处理自动化系统。根据废水的处理方法为沉淀-石灰中和法-曝气法工艺,采用了先进的自动化集成系统,并通过多种算法优化各项环节的PID控制系统,使选矿废水稳定达到废水排放指标,并循环利用了可回收矿物泥以及水资源,最后,设计整体的自动化监控系统软件,提升废水处理的管理水平。以某铅锌矿选矿为例进行工程应用,结果表明,废水处理过程的全面自动化进行工程应用,降低人力成本,出水水质达标,可以为偏僻的矿山实现了水的循环使用,保证了生产的稳定。

Design and Application of Mineral Processing Wastewater Treatment Automatic Control System

Aiming at the problems of poor water quality, unstable index and unable to be reused continuously caused by simple manual treatment of wastewater in lead-zinc mine concentrator, an efficient automatic system for mineral processing wastewater treatment was designed. According to the treatment method of wastewater is sedimentation lime neutralization aeration process, the advanced automation integrated system is adopted, and PID control system of each link is optimized by various algorithms, so that the beneficiation wastewater can stably reach the wastewater discharge index, and recycled mineral mud and water resources are recycled. Finally, the overall automatic monitoring system software is designed to improve wastewater treatment Management level. Taking a lead-zinc mine as an example, the engineering application shows that the comprehensive automation of wastewater treatment process can reduce the labor cost, and the effluent quality can reach the standard, which can realize the water recycling for remote mines and ensure the stability of production.
