近几年,中国各地都在兴建/扩建污水厂和净水厂,或者对老厂进行自动化改造。自控系统对于水处理厂高效、节能运行的重要性也得到普遍认可。DCS系统在欧美发达国家的水处理行业已获得广泛应用,有力促进了污水处理管控一体化的发展,取得了良好的经济效益和社会效益。而国内污水处理项目鲜有采用DCS,基本上都是采用PLC系统。目前国产DCS系统已在国内水行业中获得应用,在工程实施和水厂运营中显现出了较好的经济、社会效益,值得推广。
In recent years, sewage plants and water purification plants have been built / expanded in various parts of China, or the old factories have been transformed to be automated. The importance of automatic control systems for the efficient and energy-efficient operation of water treatment plants is also widely recognized. DCS system in developed countries in Europe and the United States has been widely used water treatment industry, effectively promoted the integration of sewage treatment control development, and achieved good economic and social benefits. The few domestic sewage treatment projects using DCS, are basically using PLC system. At present, the domestic DCS system has been applied in domestic water industry, showing good economic and social benefits in project implementation and waterworks operation, which is worth promoting.
