摘　　要：以无锡某污水处理厂除磷药剂自动投加系统改造为例,设计了基于反馈控制的除磷药剂自动投加系统。该系统通过出水总磷反馈,并结合进水流量数据,实现药剂的自动投加,减少了加药的药剂浪费,增加了控制精度。Taking an automatic dosing system for phosphorus removal in a sewage treatment plant in Wuxi as an example,an automatic dosing system based on feedback control for phosphorus removal is designed in this paper.The system realizes the automatic dosing of the medicament through the feedback of the total phosphorus of the effluent and the flow data of the influent,thereby reducing the waste of medicament addition and improving the control accuracy.
