CAST污水处理工艺故障诊断方法的研究与应用

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。

Application of fault diagnosis for CAST sewage treatment process

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.
