自来水厂污水处理自动控制系统设计研究自来水厂污水处理自动控制系统设计研究摘要现如今，社会发展越来越注重可持续绿色发展，为此污水处理工程愈发重要。传统污水处理主要依靠工人经验，通过手动控制及常规化的仪表监测系统来控制污水处理流程。这种方式处理效率和处理质量相对来说都偏低。为了让污水处理跟上当今社会发展需要，强化效率和改善质量双线并行，本文利用自动控制技术及相关的控制装置，对当前污水处理展开观察，设计一套适配性高的自动控制系统，以切实解决如今迫切的污水处理需求。本文研究初始点在对污水处理要求进行探究，对实务中进行污水处理工艺的流程及其特点，确定了污水控制系统的设计目标和要求。由于污水处理具有多种类型因素变量，同时还具有非线性的特性，因此在设计时利用工业以太网PROFINE作为技术支点和系统框架，构建一套主从式的具有高针对性和效率性的控制系统。在对系统控制策略以全盘性视角进行审视和设计之后，又依托于此将所需要的软硬件部分一一进行适配性开发和设计。在硬件部分中对使用到的现场各类仪表、PLC控制器的模块类型和上位机等硬件设备进行选型。在软件部分中，选用WiCC组态软件完成上位机监测界面的构建：将事先预备好的各个硬件组成，用TIA Portal软件展开预设性和对应性组态操作，并对污水处理控制中涉及到的不可或缺的环节或步骤进行控制程序编写和设计，通常来说使用的是PLG控制程序。与此同时，针对传统污水处理中难以进行有效控制和精准把握的酸碱度参数，使用了更先进的控制策略，以得到更精准的参数供给，这就是模糊PID算法，将该方案的控制模型在MATLAB中仿真，结果表达该算法能够实现预期目标，具备精确化和特出化的特点。本设计实现了自来水厂污水处理系统的自动控制，满足现代社会对污水处理的需求。自来水厂污水处理自动控制系统设计研究关键词：污水处理，PLC,MATLAB仿真，酸碱度自来水厂污水处理自动控制系统设计研究DESIGN AND RESEARCH ON AUTOMATIC CONTROLSYSTEM OF SEWAGE TREATMENT IN WATERWORKSABSTRACTNowadays,the social development is paying more and more attention tosustainable and green development,so the sewage treatment project is becomingmore and more important.Traditional sewage treatment mainly depends on theexperience of workers,through manual control and routine instrument monitoringsystem to control the sewage treatment process.In this way,the processing efficiencyand quality are relatively low.In order to make sewage treatment keep up with theneeds of today's social development,strengthen efficiency and improve qualityparallel,this paper uses automatic control technology and related control devices,toobserve the current sewage treatment,design a set of automatic control system withhigh adaptability,in order to effectively solve today's urgent sewage treatment needs.This paper studies the initial point in the sewage treatment requirements toexplore the practice of sewage treatment process and its characteristics,to determinethe design objectives and requirements of sewage control system.Because sewagetreatment has a variety of factors and variables,and also has nonlinear characteristics,so in the design of industrial Ethernet PROFINE as the technical fulcrum and systemframework,to build a master-slave control system with high targeted and efficiency.After inspecting and designing the control strategy from the perspective of the wholesystem,the hardware and software parts needed are developed and designed foradaption one by one.In the hardware part of the used field of all kinds of instruments,PLC controller module type and the upper computer and other hardware equipmentselection.In the software part,the construction of the monitoring interface of the
