DO in wastewater refers to dissolved oxygen, that is, the dissolution of oxygen in water, an important indicator of its presence in water. Dissolved oxygen levels vary with water temperature, atmospheric pressure, and salinity, and are higher in fresh water than in sea water. The above brief introduction to DO, then DO will affect the ammonia nitrogen exceeded? The following water quality online monitoring instrument manufacturers to understand together with you!

Some high-hardness wastewater, especially the dissolved oxygen scale, uses microporous aerators at the beginning of aeration, and after running for a period of time, the aerator head will be blocked, resulting in an increase in ammonia nitrogen when DO cannot be raised.

Interpretation analysis: The role of aeration is to oxygenate and stir, the blockage of the aeration head will have a certain impact on them, and the nitrification reaction is aerobic metabolism, and it is necessary to ensure that the dissolved oxygen in the aeration pool can operate normally in a suitable environment, but if the DO is too low, it will lead to the blockage of nitrification, and then the ammonia nitrogen will increase to exceed the standard.

What Are the Solutions? There Are Two Situations

1.Replace the aerator head, if the blockage caused by the low hardness operation problem can be considered this method;

2.Transform into a large hole aerator (oxygen utilization rate is too low, the fan margin is large and not bad money enterprises can consider) or jet aerator (can only use the monitoring pool water to act as a power fluid, especially the high hardness of the sewage).
