基于组态控制的污水处理网络监控系统
基于组态控制的污水处理网络监控系统作者：张学峰来源：《消费电子·理论版》2013年第01期摘要：随着我国经济的高速发展和城镇化程度的不断提高，工业污水和生活污水日益增多。
为了维持经济的持续、健康增长和生态环境的良性循环，必须对工业及生活污水加以处理。
在污水处理厂内，为了监视现场设备的运行参数和状态，需要建立一套中央监控系统。
关键词：网络监控；组态软件；网络数据库；Delphi中图分类号：TP277 文献标识码：A 文章编号：1674-7712 （2013） 02-0052-02一、本系统的总体方案污水处理有多种工艺，各污水处理厂采用的污水处理工艺、设备、土建工程、地理环境等不同，但处理的流程及控制点是有共性的。
本系统采用力控软件、Delphi软件与PLC相结合构成网络监控系统。
PLC负责控制电机等污水处理设备和采集现场参数；力控软件负责监视整个厂区，记录数据库，报表打印，报警和给Delphi控制界面发送电机运行状态等功能，Delphi 负责进行远程监控电机工作状态与调取远程数据库数据。
二、基于组态软件的控制根据监控中心的功能要求，应用三维力控组态软件和Delphi来对整个系统的上位机进行开发。
下位机用西门子MICROMASTER420通用型变频器和旋转编码器。
通过变频器实现对现场设备的调速要求，编码器和电机同轴连接，对电机的转速进行实时监测。
实现步骤为：（一）设备定义（1）选择串口通信方式，地址为数字（但其值不能为13）。
（2）通讯端口设置，跟变频器设置一致。
一般为：波特率9600，数据位8，奇偶校验为偶校验，数据位1位。
（3）附加参数设置，单击“下一部”按钮出现如下对话框，目前用户可以不管它，“PZD数据长度”为2即可（注意：用户必须把P2012的值置为2，它控制PZD的字长）。
（二）西门子变频器的配置（1）P2012的值必须设置为2，即使PZD的字长为2。
（2）P2009的值必须设置为1，即以十进制的形式发送设定频率。

基于PLC的污水处理系统毕业设计论文
基于PLC的污水处理系统师大学协和学院信息技术系电子信息科学与技术专业9 王基仁指导老师阳[摘要]随着经济的快速发展与生活水平的提高，水污染的问题日益严重，水资源短缺的压力越来越大。
只有合理地使用水资源，才是水资源可持续利用的有效途径。
为了实现这一目的，加强污水再生利用是关键。
在国污水处理的自控系统相对比较落后，污水处理成本普遍居高不下，排放的处理水的水质不稳定，所以如何建立有效的自控系统，优化运行效果，缩减运行费用，具有重要意义。
序列间歇式活性污泥法（简称SBR)，处理工艺简洁易行，占地少，布局紧凑合理，节省投资，是一种先进的污水处理工艺，本系统主要介绍了污水处理的基本工艺和流程，通过研究设计一套基于可编程序控制器（PLC）控制的污水处理模拟系统，实现了对格栅、沉淀、好氧曝气、厌氧沉淀分离以与生化池的接触消毒的模拟控制。
PLC是一种专为工业现场环境设计的计算机，抗干扰能力强，在污水处理系统采用PLC控制系统，可以大幅减轻工作人员的劳动强度,提高污水处理的运行效率, 提高自动控制的可靠性。
上位机方面，使用组态王作为上位机监控系统软件，用于对污水站的运行状态进行集中监控。
对污水站数据采集和自动控制系统的控制参数进行设置，监控设备的运行与控制状态，绘制重要参数的变化曲线。

1
具有推流型活性污 泥法的优点，即系 统中存在较大的基 质浓度梯度和较高 的絮体负荷。
2
具有完全混合型活 性污泥法较强的抗 冲击负荷能力的优 点。
3
采用鼓风曝气的方 式，具有曝气效率 高的特点。
①具有代谢功能活性的微生物群体（Ma）； ③由原污水挟带的难以生化降解的惰性有机物
②微生物自身氧化、内源代谢的残留物（Me） ； （Mi） ；
④由原污水挟带的无机物质（Mii） 。
（3） 活性污泥净化的影响因素
营养物质平衡： C源、N源、无机盐类和 某些生长素。
溶解氧量：参与处理的多为 好氧菌，其浓度不易低于2mg/L.
（1） 生物膜基本概念和构造 生物膜法的实质是微生物和微型动物附着在 滤料或某些载体上生长繁育，并在其上形成的 膜状污泥—生物膜。 污水与生物膜接触，污水中的有机污染物 被生物膜上的微生物摄取，水质得到净化，微 生物自身也得到繁衍。

常见的有三类方法：物理处理法，化学处理法，生物处理法，由于污水中各种成分的复杂性，常常将这三种方法结合使用，处理程度有一级、二级、三级。
在城市污水中常常挟带大量的呈悬浮状态的固体污染物和漂浮物，而第一种方法主要用来做一级处理，格栅机、沉砂池、沉淀池为主要构筑物。
第三种方法则用在二级处理系统，即利用微生物的呼吸作用降解掉污水中的可降解有机物，也称序批式活性污泥法（SBR），在同一反应器中完成进水、反应、沉淀、排水和闲置共5个工序。
污水二级处理系统主要由集水池、SBR池、储泥池和储水池四部分构筑物部分组成，相应的设备主要有水泵、滗水器、曝气机等。
本文采用西门子S7-200 PLC作为污水处理系统的主控器，西门子人机界面HMI SMART 700 IE V3作为上位机监控设备，结合编程软件STEP 7 MicroWIN SP9，组态软件WinCC flexible SMART V3，共同实现污水处理系统的仿真运行。

将现场检测仪表与控制设备接入各现场控制站，通过以太网将上位机与PLC进行连接，系统硬件组成如图1所示。
粗格栅及提升泵房:(1)格栅机:泵站装有格栅机2台，并装有液位计，来检测格栅机前后液位差。
通过格栅机前后液位差的检测，提示或自动启动格栅机，以清除、处理附着在格栅上的污物。
操作者可以监控画面上对格栅机的操作，同时显示出启停状态以及液位等数据。
(2)污水泵房:污水泵房内布置4台污水提升泵。
泵房内壁装有液位计，以实时检测污水液位。
通过PLC，提升泵将根据泵的状态、液位等自动投切。
当泵处于工作状态时，泵的叶片可以旋转以增加画面的丰富性。

WinCC组态软件在污水处理中的应用
WinCC组态软件在污水处理中的应用dujing导语：结合某一个排污量大、污水成份复杂、控制设备多的汽车创造厂在污水处理改造工程中，采用20 世纪90 年代国际上先进的工控组态软件WinCC，开辟了相应的污水处理的控制程序1、引言改革开辟以来，我国工业企业日新月异，规模日益壮大，先进设备广泛应用，工艺科技含量越来越高。
在消费中，自动化技术已经普及到各个领域、各个车间，这充分讲明我国民族工业的逐渐强大。
但是相比之下，在不少企业的污水处理中自动化程度不高，采用的软硬件落后，甚至有的控制点还依靠于人工控制，无形中制约了企业技术先进化的开展。
为此我们结合某一个排污量大〔平均流量80T/H〕、污水成份复杂〔包括面漆水、电泳水、车身浓脱脂水等〕、控制设备多〔需要600 多控制点〕的汽车创造厂在污水处理改造工程中，采用20 世纪90 年代国际上先进的工控组态软件WinCC，开发了相应的污水处理的控制程序。
在一年多时间的实际运行中，各项工艺指标都到达了预期的效果，用户特殊满足，进而辞别了长期污水排放不达标的被动场面。
2 、WinCC 软件的简介工控组态软件WinCC 是一个集成的人机界面〔HMI〕系统和监控管理系统，它是西门子公司在经过自动化领域中的先进技术和微软公司强大软件功能的产物，WinCC 是视窗控制中心〔WindowsControlCenter〕的简称。
它包括图形设计器、报警记录、标[table][tr][td][/td][/tr][/table]记记录、报告设计器、全局脚本、控制中心、用户管理等功能，使其具有高性能的经过耦合、快速的画面更新、以及可靠的数据管理[1~2>。
3、系统构成对于一个普通的水处理工程就其工程量而言是宏大的，特别是一些大型工程，所以开辟控制程序、调试的时间不能不成为必须考虑的因素。
但是出于可靠性的考虑，将控制系统的功能别离是必须的，即：下位机执行保护、控制和数据的收集，脱离上位机也能独立对系统发展控制，上位机执行显示、控制、报警、储存等。
