SGR-PLC在中水回用控制系统中的实例应用

Application of SGR-PLC in reclaimed water reuse control system

企业末端治理后的中水再生水回用是节约水资源、循环综合利用极其重要的一环,而中水回用采用的超滤膜(UF)+反渗透(RO)膜工艺是大多数企业的首选,也是目前较为成熟的处理工艺之一。控制系统的设计性能、匹配度,决定了整套系统的运行可靠度,无论是从各处理单元点的控制还是整套系统工艺流程自动化的控制,都是运行的重中之重。结合应用实例详细介绍了SGR-PLC自动控制系统在安徽某化工股份有限公司的高效运行,并就如何更安全可靠地应用在中水回用双膜法系统中,对膜系统运行控制出现的常见问题进行罗列并提出应对措施。

The reuse of reclaimed water after treatment at the end of the enterprise is an extremely important part of saving water resources and recycling and comprehensive utilization,and the ultrafiltration membrane(UF)+reverse osmosis(RO)membrane process used in the reuse of reclaimed water is the most important part of the enterprise.The first choice is also one of the more mature treatment processes at present.The design performance and matching degree of the control system determine the operational reliability of the entire system.Whether it is from the control of each processing unit or the automation of the entire system process,it is the top priority of operation.This paper introduces the efficient operation of the SGR-PLC automatic control system in an Anhui Chemical Co.,Ltd.in detail with application examples,and discusses how to more safely and reliably apply it to the double-membrane system for reclaimed water reuse.Frequently asked questions are listed and countermeasures are proposed.
