Online Dissolved Oxygen Meter Wastewater Monitoring System

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. The DUC2-DO online dissolved oxygen controller developed and produced by Daruifuno can be used with a digital fluorescence dissolved oxygen sensor to achieve real-time continuous monitoring of the dissolved oxygen value of water quality. The controller is equipped with 2 settable SPST relays and 2 channels of 4-20mA current, which can be connected to aeration equipment to accurately control the dissolved oxygen value of wastewater. The wastewater dissolved oxygen quality monitor plays a very important role in industrial wastewater supervision. It can improve the efficiency of wastewater treatment and protect the environment and people's health.

Currently, there are two widely used industrial wastewater dissolved oxygen water quality monitors, namely electrochemical method and fluorescence method.
The electrochemical method is a method that uses electrodes to measure water samples. The electrode is a reaction electrode suitable for use in solution, such as a glass membrane electrode, used to detect the oxygen content in wastewater. This method is technically more accurate and more sensitive, and can quickly and accurately measure dissolved oxygen in wastewater.
The fluorescence method is an optical-based method that uses fluorescence to analyze the dissolved oxygen content in wastewater. The fluorescence method has high sensitivity and accuracy, and can monitor under low dissolved oxygen content. At the same time, the fluorescence method has little impact on other interfering substances in wastewater, so it is widely used in monitoring dissolved oxygen in industrial wastewater. The DUC2-DO dissolved oxygen controller can be connected to the fluorescence dissolved oxygen sensor developed by daruifuno, integrating display, controller, data transmission, history recording and other functions.

In addition to monitoring the dissolved oxygen value of wastewater, online dissolved oxygen meters can also be used in the following situations:
Aquaculture: Ensure the respiratory needs of aquatic organisms, real-time monitoring of oxygen content, automatic alarm, automatic oxygenation and other functions.
Water quality monitoring of natural waters: monitor the degree of pollution of waters, self-purification ability, and prevent biological pollution such as eutrophication of water bodies.
Sewage treatment, control indicators: anaerobic tank, aerobic tank, aeration tank and other indicators are used to control the water treatment effect.
