sewage treatment
The paper introduces a distributed control system of sewage treatment, and the core of the system is PLC. The structure of the control system, the assignment and implementation of the tasks, the control scheme and the design concept of program are expounded. The way of central monitoring management and dispersing control is used by the control system; the long一distance control and monitoring of field equipment are uncharged of the upper computer; the software program of designs uses Intouch7. 0. The specific technology, equipment, the controlling of main parameter and several running data are uncharged of the PLC stations, and the software program of designs uses Concept 2. 2XL with online tracking and outline simulating. MB+ net is adopted by the communication between the upper computer and the PLC stations, with its simply building net, quickly running and stable communication. The automatic control of PLC has been successfully completed in sewage treatment, which has improved the operation efficiency and management level of sewage treatment equipment
Introduced to take PLC as the distribute type control system of core in the wastewater treatment system of apply。Concretely described the structure, mission of the control system an allotment and carry out, the way of control and the thought of the program design. The way controled the concentration monitor of the system adoption a management and scattered a control, the place of honor machine be responsible for the spot the long range of the equipments control and surveillance, software adoption Intouch7. 0 draw up.The PLC native station is responsible for to the concrete craft, equipments and is mainly controled parameter to carry on control and collect various movement data, the program design adoption have on-line follow with off-line imitate the Concept of true function 2. 2 XL software.Place of honor machine and of the PLC adoption set the net be quickly simple and circulate speed, correspond by letter the stability strong MB+net.The whole control system successfully solved the PLC controls a problem in the automation within wastewater treatment and raised a wastewater treatment equipments to circulate an efficiency and manage level.
介绍了以PLC为核心的分布式控制系统在污水处理系统中的应用。具体叙述了控制系统的结构、任务分配及实现、控制方式和程序设计思想.控制系统采用集中监测管理、分散控制的方式，上位机负责现场设备的远程控制和监视，软件采用Intouch7. 0编制。PLC本地站负责对具体的工艺、设备、主要被控参数进行控制及采集各种运行数据，程序设计采用具有在线跟踪和离线仿真功能的Concept 2. 2XL软件。上位机与PLC之间采用组网简单、运行速度快、通信稳定性强的MB+网 。整个控制系统成功地解决了PLC在污水处理中的自动化控制问题，提高了污水处理设备运行效率和管理水平。
近年来，为了实现高质量、低消耗、稳定可靠的运行。国内外许多污水处理厂采用了现代先进控制技术和计算机技术，从而构成计算机监督、控制、管理系统.使系统优化运行。而可编程逻辑控制器（PLC）则是以微处理器为核心。综合了计算机技术自动控制技术和通信技术而发展起来的一种新型、通用的自动控制装置。具有结构简单、性能优越、可靠性高、灵话通用、易于编程、使用方便等优点等。银川市第一污水处理厂采用了SBR工艺及以PLC为核心的控制系统，日处理污水10 x 104 t处理后的达标污水可用于农业灌溉。
