Abstract：For the sake of the exaltation of the efficiency and the automation degrees of water factory, it is adopted the ControlLogix system of Rockwell, which carry out automatic supervision of the dissolved air flotation technology. The application of the system of PLC（Programmable Logic Controller）-HMI（Human Machine Interface）of ControlLogix in dissolved air flotation technology is emphasized. The result shows: the design of the hardware and software of the system is reasonable, and the expectant function is fulfilled, which proved the possibility of that project.
