摘要
本文分析了CAST污水处理工艺故障诊断的特点和需求。在此基础上,提出了建立CAST工艺故障诊断系统的思路和方法,利用自动化监控系统实现在线故障监测和报警,利用故障树分析法构建故障诊断模型,结合运行参数趋势图,实现故障快速诊断。文章通过实例分析,介绍了该方法在污水处理厂的实际应用。
This paper analyzes the characteristics and requirements ot CAST wastewater treatment process fault diagnosis. On this basis, it put forward methods to establish the CAST process fault di- agnosis system： use the automatic monitoring system to realize online monitoring and fault alarming, construct fault diagnosis model through the fault tree analysis method, and perform the fast fault diag- nosis combined with the operation parameters trend chart. It introduces this diagnosis process by a practical application in a sewage treatment plant.
