一般水厂的滤池分格较多,反冲洗要求轮流顺序进行:每格滤池要求滤料上部水深稳定在1.5—2米之间,自动控制有一定难度,本文提出一种用小型可编程序控制器组成的系统,以I/O接口和优化控制理论实现了自动顺序反冲洗和水位控制稳定的要求,并在深圳笔架山水厂的实际应用中取得成功。
General water filter more points, backwash requires rotation in order: each filter requires water depth above the filter stable at between 1.5-2 meters, automatic control has a certain degree of difficulty, this paper presents a small can be made Program controller composed of the system to I / O interface and optimization of control theory to achieve the automatic order of backwashing and water level control of the stability requirements, and in Shenzhen Beacon Hill water plant in the practical application of success.
