摘　　要：南楼水厂采用集散型控制系统。由中控室的2台监控计算机通过投加间分控站、滤池分控站及送水泵房分控站PLC实现全厂生产管理的在线监控,并在线连续监测各环节的水质参数(浊度、pH值、余氯值)、过程参数(水位、液位、压力、流量、电气参数)及设备运行参数(频率、冲程、阀门开度等),实现生产的优化控制,强化工艺的处理效果,确保出厂水水质。Nanlou Water Treatment Plant adopts a distributed control system composed of computers and PLC. The on-line monitoring of whole production and management is achieved using two supervisory computers in the central control room and PLCs in the sub-control stations for dosing chamber, filter and water pumping station. The continuous monitoring of water quality parameters （turbidity, pH value and residual chlorine） , process parameters （water level, liquid level, pressure, flow rate and electrical parameters） and equipment operating parameters （frequency, stroke, valve aperture and so on） is performed. The quality of finished water is ensured by achieving the optimal production control and enhancing the treatment effect.
