Dissolved oxygen refers to molecular oxygen dissolved in water, usually recorded as DO, expressed in milligrams of oxygen per liter of water and saturation percentage. The saturated content of dissolved oxygen is closely related to the partial pressure of oxygen in the air, atmospheric pressure, water temperature and water quality. Dissolved oxygen plays a decisive role in actual sewage and wastewater treatment operations. The deterioration or excessive fluctuation of this indicator will often lead to large fluctuations in the stability of the activated sludge system, which will naturally have a very obvious impact on the treatment efficiency. The OPD790 Online Dissolved Oxygen Sensor developed and produced by Daruifuno adopts the principle of optical method, digital communication, internal storage of calibration data, and is plug-and-play. Paired with the DUC2-DO online Dissolved Oxygen Controller, it can realize continuous online monitoring of the dissolved oxygen value of sewage and wastewater, and control the dissolved oxygen content in the water. Dissolved oxygen in industrial wastewater is one of the important indicators to measure the quality of water bodies. High-quality water bodies are mainly because the water contains enough oxygen to maintain the oxygen demand in the ecological system. However, in the process of industrial production, industrial wastewater will bring a large number of chemical pollutants, which will consume oxygen in the water and reduce the dissolved oxygen content in the wastewater. Therefore, monitoring the dissolved oxygen content in industrial wastewater is of great significance for judging the quality of water and treating wastewater.

Industrial wastewater is a very common wastewater source that contains high concentration of organic and inorganic pollutants, causing great harm to the environment. In order to protect the environment and people's health, the treatment and supervision of industrial wastewater have become indispensable tasks. In terms of water quality monitoring, the application of water quality monitors has brought many conveniences and efficiency improvements to the monitoring process.
Wastewater produced during industrial production has different water quality characteristics due to the influence of different production processes. But in general, the pollution characteristics of industrial wastewater can be summarized as follows:
1. Highly variable. Due to the uncertainty of the industrial production process itself, industrial wastewater usually has characteristics such as temporal variability, spatial variability, and batch variability.
2. Contains high concentrations of chemicals. Industrial production is usually accompanied by the use of a large number of chemicals, which are released into wastewater during the production process, resulting in significant chemical pollution of wastewater.
3. It has certain toxicity and danger. Some industrial wastewater contains toxic and harmful substances, such as heavy metals, organic solvents, etc. These substances cause greater harm to the environment and human health.
Online dissolved oxygen analyzers can be set up in key locations such as industrial wastewater treatment stations and pollution discharge outlets of key enterprises to monitor the dissolved oxygen content in industrial wastewater in real time. Handheld dissolved oxygen monitors can be applied to on-site for mobile monitoring. Wastewater monitoring greatly facilitates on-site monitoring work.
