摘　　要：针对现阶段我国污水处理厂的计算机管理和自动控制系统水平较低,污水厂的正常运行率和出水合格率不高,应用三菱Q系列PLC等设备,通过以太网实现上位机监控,CC-link现场总线实现对于大面积分散厂区的网络化控制和管理,专门对橡胶厂在生产过程中产生的碱性工业废水进行净化、中和以及生化氧化等处理,使其最终达到"中水"的排放标准。由于应用软件控制代替了硬件控制,不仅提高了污水处理厂的正常运行率,而且为自动化控制的顺利实现创造了条件。For the low level of computer management and automatic control system of the present stage of China's sewage treatment plants,and the low rate of the normal operation of wastewater treatment,using the Mitsubishi Q series of PLC,etc,monitoring by the Ethernet,the large-scale distributed factory by CC-link is managed and controlled.Especially for the alkaline industrial wastewater produced by the rubber factory,by neutralization and biochemical oxidation processing,the system will purify the water,making it up to the emission standard.Instead of hardware control,software control can improve the rate of the normal operation,and create the conditions for the smooth realization of the automatic control.
