Automatic control online dissolved oxygen controller meter 

In sewage treatment plants, it is necessary to monitor the value of dissolved oxygen in water quality. DUC2-DO dissolved oxygen controller can not only connect digital dissolved oxygen sensor to realize real-time online monitoring, but also has control function. The value of dissolved oxygen in sewage can be controlled by the following methods: Increase oxygen supply: The dissolved oxygen value in sewage can be increased by increasing oxygen supply, such as increasing aeration equipment or increasing water flow; Reduce the discharge of organic matter: organic matter can consume oxygen in sewage, so reducing the discharge of organic matter can reduce the oxygen consumption in sewage, thereby increasing the value of dissolved oxygen; Optimize the biological treatment process: The biological treatment process can convert organic matter into inorganic matter, thereby reducing the content of organic matter, and can also increase the dissolved oxygen value in sewag…
