【摘要】：随着社会进步,经济发展,人民生活水平不断提高,人们改善生态环境的能力和范围也在不断加大。污水处理在环境改善中占据了重要的地位,但我国污水处理行业和国外相比还较落后,自动化控制仍处于起步阶段,因此,研究基于计算机控制技术的污水自动化处理过程控制系统,具有重要的现实意义。本文介绍了污水处理相关知识、污水处理工艺流程以及我国污水处理自动化控制系统的研究现状与发展趋势。文章对西安市第六污水处理厂的自动化控制系统组成结构以及系统实现的主要功能、自动化系统的设计方案及理念、污水厂内重点设备的控制及信号接入方式进行了详细说明。论文通过西安市第六污水处理厂的工艺特点及环境条件,分析了全厂工艺的自动化控制系统,并对该厂的自动化控制系统、仪表系统的组成及设备选型情况进行了叙述,重点说明了自动控制系统中现场控制站的设置及设备控制情况,通过自控系统中的软件体系实现了污水处理系统过程的数据采集、控制、显示,以及异常报警、日常报表打印等功能。对其中涉及的工艺控制显示、事件驱动和报警、操作窗口功能、生产指标监控、设备运行参数监测、工艺参数设定等进行了分析。
[Abstract]:With social progress, economic development, people's living standards constantly improving, people's ability and scope to improve the ecological environment are also increasing. Sewage treatment plays an important role in environmental improvement. However, the sewage treatment industry in our country is still relatively backward compared with foreign countries, and the automation control is still in its infancy. Therefore, the paper studies the sewage automation process control system based on computer control technology. This paper introduces the related knowledge of sewage treatment. The research status and development trend of sewage treatment automation control system in China. This paper introduces the structure of automatic control system of Xi'an 6th sewage treatment plant and the main functions of the system. The design scheme and concept of the automation system, the control of the key equipments in the sewage treatment plant and the method of signal access are described in detail. The technological characteristics and environmental conditions of Xi'an 6th sewage treatment plant are introduced in this paper. The automatic control system of the whole plant process is analyzed, and the composition of the automatic control system, the composition of the instrument system and the selection of the equipment are described, with emphasis on the setting of the field control station and the equipment control situation in the automatic control system. The functions of data acquisition, control, display, abnormal alarm, daily report printing and so on are realized through the software system of automatic control system. Operation window function, production index monitoring, equipment operation parameter monitoring, process parameter setting and so on are analyzed.
