摘　　要：针对APMP废水中COD、BOD含量高的特点,结合厌氧-好氧生化处理法,设计了基于S7-300 PLC的APMP制浆废水处理过程控制系统。According to the characteristic of high contents of COD, BOD of the APMP wastewater, the wastewater treatment system adopts anaerobic-aerobic process and the process control system is designed based on S7-300 PLC. Aiming at the control difficulty of pH value and dissolved oxygen value of the aeration tank, the paper introduces united control ofpH value with fuzzy feedforward and non-linear gain PID and the control of dissolved oxygen value of the aeration tank in detail. The control algorithm is reliable and feasible, and the control system functions very well.
