基于含氰废水的强抗干扰在线测控系统

在废水现场氰检测传感器经常受到干扰,设计了一种具有强抗干扰能力的在线检测系统。该系统采用氰检测传感器样品池自动复位的关键技术,自动连续完成抗干扰的各种操作,将传感器每次检测时的状态都控制在相同条件水平上,解决了系统在现场运行中所产生的各种干扰问题,强化了系统在线测控能力,系统检出限<0.5mg/L。

Strong anti-interference on-line test and control system based on CN waste water

The CN~ test sensor is often interfered in the scene of waster water.A kind of on-line test and control system with strong anti-interference ability of CN~ waste water is designed.The key technology with sampling room auto-reset of CN~ test sensor is adopted,all kinds of operations to resist disturbance can be completed automatically and continually.Test state of sensor is controlled at same level every time.All kinds of interference questions in the scene are solved.On-line test and control ability of the system is consolidated,and the test limit of the system<0.5 mg/L.
