摘要
净水厂V型滤池具有出水水质好、滤速高、运行周期长、反冲洗效果好、节能和便于自动化管理等优点,已在我国越来越多的净水厂中使用,本文研制的V型滤池反冲洗控制系统是以多PLC组网的方式,结合V型滤池工艺流程的管控一体化综合系统.控制系统采用PLC组网技术和单组V型滤池的顺序控制策略降低了系统的控制风险.保证了城市供水安全。
The V-filter in water plants with good water quality, filtration rate, long running cycle, effective backwashing, energy-saving and ease of automation manage, it have being used in more and more water plans. The V-filter backwashing control system being researched in this article is a intergrated system based on multi-PLC network and technol- ogy of V-filter. Used PLC network technology and single V-filter sequence control strategy, this system reduced the risk of control and ensured safty of the city water supply.
