A detailed description was made on the process of wastewater treatment, which included water supply, reaction, precipitation, and drainage. On the basis of the process above, the system control scheme was established. The hardware and software of SBR system were devised as well as the man-machine interface. The aspects of hardware mainly included type selection of PLC and PLC I/O device. For the software, it mainly included the program flow chart, program design and simulation. Furthermore, man-machine desi...
