摘　　要：介绍了一套自主开发的CAST工艺自控系统。在 4个月的连续运行中 ,成功地实现了对一个处理城市污水的CAST反应器的自动控制。该系统通过计算机中的控制软件实现对CAST反应器的各种工艺设备的时序控制 ,结合液位传感器等设备可实现对CAST反应器的反馈控制。控制操作界面友好 。In this paper, an Automatic Control System for a lab-scale CAST reactor was developed independently. During continuous operation at the foregoing four months, the CAST reactor treating municipal wastewater was automatically controlled by this system successfully. The sequential control for all of the process equipment of the CAST reactor could be achieved by the software in a computer, and furthermore, the feedback control for the CAST reactor could be achieved if there were some on-line sensors for such as liquid level, DO and OPR levels. The operation interface of his system was very friendly, and its flexibility and transferability were also very good.
