文档介绍：1 摘要序批式活性污泥法( Sequencing Batch Reactor ),简称 SBR 。是一种中小型的污水处理方法。 SBR 工艺污水处理计算机监控系统的核心是可编程序控制器( PLC )。采用 PLC 不仅能够适应水处理系统的工艺特点,而且代表了现代工业的发展方向。随着工业自动化的普及与发展,要求有人家先进、稳定、可靠的监控设备加入到控制系统中,以完成数据的采集以及设备的安全运行。作为当今工厂企业重要的自动化控制设备之一,可编程逻辑控制器( PLC )已经被广泛的用于现代工业控制系统中,尤其适用于逻辑、顺序过程控制。它正随着计算机、通讯、网络等技术的进步全面迅速发展。关键词污水处理,序批式活性污泥法, SBR ,可编程序控制器 2 ABSTRACT Sequencing Batch Reactor, which iscalled the SBR law ,isakind ofcenter and small sewage treatment method .The core ofSBR craft sewage puter supervisory system isthe programmable foreword controller(PLC).Using PLC not only could adapt tothe craft characteristic ofthe water disposal system, but also represents the modern industry developed direction. Along with the popularization and the development ofindustrial automation , inorder plete the data gathering and the safety running ofthe equipment, more advanced, stable and reliable monitoring equipments are required tojoin the control system. Asone ofthe important automation control devices innowadays factories, the programmable logical controller(PLC) has already been used widely inthe modernindustry control system, especially for the logical, order process control, Itisdeveloping rapidly along withthe progress puter, communication ,network and soon.
