摘　　要：水厂滤池的反冲洗要实现各种阀门的控制及进水、排水、气冲、气水混合冲等,这是一个复杂的过程。本设计通过硬件的配置和软件的应用,利用S7-300PLC软冗余技术,实现了各滤池反冲洗控制、滤池恒水位运行以及异常运行状态报警等功能,有效降低了操作强度,提高了滤池的生产效率和产品水质量。The backwashing of the filter is a complicated process,which needs to complete the control of various valves and influent,drainage,gas water mixed flushing,etc.Through the configuration of hardware and the application of software,the backwashing control of filter,the constant water level operation of the filter and alarm of abnormal running state are realized by PLC soft redundancy,which can effectively reduce the operation intensity and improve the production efficiency and product water quality.
