Rotork智能动脉高技术环境升级

---

新建硝化活性污泥厂已建成环境改善项目的一个主要部分,该项目确保遵守欧洲淡水鱼指令规定的严格最后许可许可

新厂配有最先进控件、条件监控和先进仪表优化流程并节能。流程完全自然和无化学作用取决于前端选择机厂两侧注入再激活淤泥,比例由下游过程条件决定。这些常受流水平变化和环境天气条件等环境影响

Flowmeters and oxygen sensors in the activated sludge plant lanes communicate data to a PLC which then signals positional changes to two Rotork IQPro modulating electric actuators operating 1400mm Dezurik plug valves on a pipe feeding the selector plant from surplus activated sludge storage tanks.  The accurate positioning of the two valves determines the flow rates into both sides of the selector plant to ensure that the correct mix is introduced into the activated sludge process.  Control and instrumentation communication on the plant utilises a Profibus digital network to provide swift and comprehensive data transmission and economical installed wiring costs.  Connectivity with the IQPro actuators is by means of Rotork's Profibus highway termination module, which enables the bus to be connected and disconnected from the actuators if necessary without interrupting communication with other devices on the network.

激活淤泥进程完成后,残留淤泥泵归最后解决槽,从那里加厚并最后用作燃料为工地发电
