一、目前给水厂过滤自动控制的现状过滤是水质净化中的一道重要工艺,目前应用的滤池类型很多,应用广泛的重力式滤池中,能够自动运行的滤池,一类是依靠虹吸原理采用一套水力自动运行装置的滤池,以虹吸滤池和重力式无阀滤池为代表,另一类滤池则是以V型滤池自动化、移动罩滤池为代表,以计算机作为自动控制核心操作机电装置动作来实现滤池自动化。前一类滤池
First, the current state of the water filter plant automatic control filter is an important process in the purification of water quality, the current application of many types of filters, widely used in the gravity filter, to automatically run the filter, one is to rely on the principle of siphon Using a set of hydraulic automatic operation of the filter device to siphon filter and gravity-type valve-free filter as the representative, while the other is based on the V-filter automation, moving cover filter as a representative to the computer as an automatic Controlling the core to operate the electromechanical device to automate the filter. The former type of filter
