Research Of Control Of Ozone Plant Method In Nan Zhou Water Treatment

This paper introduces the characteristic of NanZhou Water Plant technologicprocess.Detailedly introduces the characteristic of ozone treatment plant technologic processand equipment.Emphatically analyses and researches control system of ozone treatment plant.Concerning its complexity, large amount of controlling points, decentralized controlpoints and strict control, it adopts advanced PLC control and applies various kinds of the fieldbus technique to meet different levels of communication requirements with ozone treatmentplant. Carefully thoroughly analyses and researches control system of ozone treatment plantfrom hardware configuration, network communication, program design and systemmonitoring four aspects.Ozone generator is looked on as at the heart of equipment in ozone treatment plant. Withcontrol system design, it adopts PLC control and microprocessor control. Power supply unitadopts microprocessor with strong function, small size, high reliability and low price, and theother part adopts (e.g.auxiliary equipment) adopts PLC with strong function, high reliability,convenient programming and easy Expansion. It combines with the advantage of PLC controland Microprocessor control to achieve optimum control for ozone generator.
