污水处理系统的设计与调试摘要：污水处理系统的效益巨大，但运行成本高，经济效益差，为了让污水处理技术有效的实现使系统能够连续稳定运行，保证出水水质达标，将自动控制技术应用与污水处理中，提高污水处理的自动化水平已成为污水处理中的关键问题。本文以污水处理厂的控制系统为研究背景，结合污水处理工艺，探讨PLC及其网络在污水处理厂中的应用，并充分考虑在线检测仪表在控制系统中的作用。文中主要介绍了PLC、污水处理工艺、控制系统硬件、软件配置以及处理厂自动控制系统的实现。关键词：PLC、污水处理、智能控制、SBRABSTRACT：Thesewagetreatmentsystembenefitishuge,butthemovementcostishigh,theeconomicefficiencyisbad,inordertoletthesewagetreatmenttechnologyeffectiverealizationenablethesystemstablytomovecontinuously,guaranteedthewaterleakagewaterqualitystandards,intheautomaticcontroltechnologyapplicationandthesewagetreatment,enhancesthesewagetreatmenttheautomatedleveltobecomeinthesewagetreatmentthekeyquestion.Thisarticletakethesewagetreatmentplantcontrolsystemastheresearchbackground,theunionsewagetreatmentcraft,discussesPLCandthenetworkinthesewagetreatmentplantapplication,andfullconsiderationonlineexaminationmeasuringapplianceincontrolsystemfunction.InthearticlemainlyintroducedPLC,thesewagetreatmentcraft,thecontrolsystemhardware,thesoftwaredispositionaswellasthetreatmentplantautomaticcontrolsystemrealizationKeyword:PLC,Swagetreatment,Intelligencecontrol,SBR目录第一章绪论........................................................................................................................51.1前言................................................................................................................................51.2水行业的发展趋势对电控系统的典型要求...............................................................51.3污水处理厂控制系统简介...........................................................................................71.4自动化控制系统的设计...............................................................................................71.5本文主要研究内容......................................................................................................8第二章污水处理工艺介绍.................................................................................................82.1污水的污染指标..........................................................................................................82.2污水处理工艺..............................................................................................................92.3SBR工艺介绍.............................................................................................................11第三章可编程控制器（PLC）简介.................................................................................123.1概述.............................................................................................................................123.2PLC的特点.................................................................................................................133.3PLC的分类.................................................................................................................153.4PLC各部组成.............................................................................................................163.5PLC的主要技术指标..................................................................................................183.6PLC的工作原...
