近年来,污水处理厂已成为各个城市最重要的基础设施之一.尤其是中小城市,新建或扩建污水处理厂已成为当地政府改善人民生活水平的头等大事.随着自动化技术、计算机技术的不断发展、完善,污水处理厂的自动化水平也相应提高.本课题是分布式污水处理测控系统中设计与应用,基于PLC和组态软件对污水处理厂的控制系统进行了改造,通过了解监测对象的工艺流程,构建基于组态软件的分布式监测系统,选择适当控制监测设备,设计出自动监测程序.PLC控制器以其技术成熟、通用性好、可靠性高、安装灵活、扩展方便、性能价格比高等一系列优点,在工业控制中得到了越来越广泛的应用.本文主要介绍了污水处理厂自动控制系统的组成、功能及结合组态软件实现污水处理厂得自动控制.在污水处理中采用组态软件和PLC结合实现的系统改造后,提高了自动控制的可靠性,不仅减轻了工人的劳动强度,而且提高了污水处理厂的运行效率和运行效益,实现了污水厂生产管理的科学性.

In recent years, sewage treatment plants have become the city one of the most important infrastructure. Especially small and medium cities, new or expanded sewage treatment plant has become a local government to improve people's living standards a top priority. With the automation technology, computer technology continues to develop, improve the automation level of the sewage treatment plant is also increased accordingly. This topic is a distributed control system of wastewater treatment design and application of software-based PLC and configuration of the sewage treatment plant control system has been transformed, by understanding the process of monitoring objects, building configuration software-based distributed monitoring system Select the appropriate control and monitoring equipment, design of automatic monitoring program. PLC controller with its mature technology, versatility, reliability, installation flexibility and easy expansion, a series of high cost performance advantages, in the industrial control has been more widely used. This paper describes the automatic control system for sewage treatment plant composition, functions and configuration software with the sewage treatment plant was automatically controlled. Used in sewage treatment and the PLC configuration software with the system modified to achieve improved reliability of automatic control, not only reduced labor intensity, but also improve the operating efficiency of sewage treatment plants and operating efficiency to achieve a wastewater treatment plant Production and management of science.
