PLC在污水处理中的应用

The application of PLC in the sewage treatment

环境保护是我国的一项基本国策。随着国家西部大开发战略的推进和三峡工程的兴建,三峡库区的环境保护,尤其是库区沿江水污染的防治已陆续启动。至2005年规划,城市污水处理率将达到60%,工业废水处理率达到90%,达标排放率达到80%。为此采用先进、实用的技术改造传统工艺,在环保工程中大力、广泛采用先进的自动控制技术,是推动环保产业升级,实现环保发展战略的重要环节。以下就重庆川仪控制系统工程有限公司承建的北碚污水处理厂自动化控制系统进行阐述。

For the example of automatic control system of Beibei＇s sewage treatment plant which constructed by chongqing sichuan instrument control system Co., Ltd, the applications of PLC technology in sewage treatment is illustrated. System had rational layout, advance, and high automation degree, and achieved good social and economic benefits.
