天津石化污水处理工程电气控制系统设计

针对中石化天津分公司已有废水处理设施中高浓度、难降解COD废水,采用高效生物反应器(ABR)进行处理,使废水净化,达到排放指标;文章针对此废水处理系统,设计一套全自动控制系统,系统通过S7-400冗余控制器对工艺设备进行控制,中控制室设置SCADA远程监控站,对整套污水处理系统的远程监视和控制,实现污水处理系统自动化控制,有效减轻操作人员工作负荷。

Aiming at the high concentration and difficult to degrade COD wastewater in the existing wastewater treatment facilities of Sinopec Tianjin Branch, the Anaerobic Biological Reactor (ABR) is used to purify the wastewater and reach the discharge target. A set of automatic control system is designed, in which the process equipment is controlled by S7-400 redundant controller, and the SCADA remote monitoring station is set up in the control room to monitor and control the whole sewage treatment system, thus realizing the automatic control of sewage treatment system and effectively reducing the workload of operators.
