Dissolved oxygen refers to the amount of oxygen dissolved in water, expressed in milligrams of oxygen per liter of water (mg/L). Some organic compounds undergo biodegradation under the action of aerobic bacteria, which consumes dissolved oxygen in the water. If the dissolved oxygen is not replenished in time, anaerobic bacteria in the water body will multiply quickly, causing the water body to turn black and smelly. In industrial wastewater supervision, the dissolved oxygen water quality analyzer provides real-time monitoring and early warning functions for the industrial wastewater treatment process. By monitoring the dissolved oxygen content in industrial wastewater, the effect of wastewater treatment can be reflected in a timely manner, abnormal situations can be discovered, and wastewater treatment measures can be adjusted in a timely manner to ensure the stability of wastewater treatment efficiency and treatment effects.
