Practical training system of sewage treatment

The invention relates to a practical training system of sewage treatment. The practical training system comprises a grid pool-lift pump-grit chamber process unit, an anaerobic tank-anoxic tank process unit, an aerobic tank-secondary sedimentation tank process unit, a sludge treatment equipment process unit, a control unit, monitoring software and a pipeline unit, wherein the grid pool-lift pump-grit chamber process unit, the anaerobic tank-anoxic tank process unit, the aerobic tank-secondary sedimentation tank process unit and the sludge treatment equipment process unit are connected through the pipeline unit, the control unit and the monitoring software automatically control the practical training system of the sewage treatment through a power supply, a hardware circuit and operating software. The practical training system of sewage treatment is arranged according to the actual production technological process of a sewage treatment plant, the commonly used AAO (Anodic Aluminum Oxide) sewage treatment process
