The invention discloses an accurate control method for dynamic sludge age of a sewage treatment plant. The method comprises the following steps: determining a daily residual sludge discharge quality theoretical value; automatically controlling the residual sludge pump according to the daily residual sludge discharge quality theoretical value; and after the theoretical value of the daily residual sludge discharge quality is completed, calculating a corresponding actual feedback aerobic sludge age value. The residual sludge discharge amount and the sludge updating rate are accurately controlled, and stable operation of a sewage treatment plant is guaranteed. 本申请公开了一种污水处理厂动态泥龄精准控制方法。该方法可以包括：确定每日剩余污泥排放质量理论值；根据每日剩余污泥排放质量理论值，进行剩余污泥泵的自动控制；每日剩余污泥排放质量理论值完成后，计算对应的实际反馈好氧泥龄值。本发明实现精准控制剩余污泥排放量及污泥更新速率，保证污水处理厂的稳定运行。
