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 .
