Research content and research object. The Coagulant Dosage Automatic Control System is discussed emphatically. Including the relation is put up between target standard and the infection factor by date analyzed chart and educational established and sum up the best working point. The target standard including SS COD and OIL .The infection factor including the dosage of PAC PH Mill INTENSION and TIME. On the basis of craft character and control request, it makes a selection of scheme to the whole control system. Finally a scheme is chosen and described as follows: CPU222 of SIEMENS PLC S7-200 is used as the control kernel. V606IC TOUCHER is used as communication man and machine. Controlling pump, compressor, metric pump of system by gathering andanalyzing the flow, PH of raw water .

重点探讨系统的投药自动化，包括系统的数学模型建立的过程，通过数据分析，采用图表和方程式建立系统排放指标(SS、CODcr、含油量)，与各种因素(PAC用量、PH值、搅拌强度、时间)的关系，确定系统的最佳工作点；根据系统工艺特点以及控制要求，对控制系统设计方案进行了选择，确定以西门子PLC(S7-200 CPU222)为控制核心，V606IC10触摸屏作人机界面，通过对原水流量和PH计采样、分析，实现系统中的泵、风机、计量泵等控制；文中从功能上简要地介绍监控系统和给出了自动化原理构成图、PLC软件流程图及部分主要程序。
