摘要
污水处理厂通过自控系统改造,将变频调速技术应用于恒压供水,保障了循环水供水管网系统压力的平衡,取得了良好的节能效果。
Through improvement of auto-control system for sewage treatment plant, speeds controlling process by frequency converter is adopted for constant pressure water supply system, the pressure balance of piping system of recycle water supply is retained, and energy saving is successfully achieved.
