What is the high efficiency ammonia nitrogen wastewater treatment ammonia nitrogen technology?

Mar 04, 2019

The principle of treating wastewater with high concentration of ammonia nitrogen must be explained from the properties and characteristics of ammonia nitrogen.

The so-called ammonia nitrogen (nh3-n), namely ammonia nitrogen, is the nitrogen in the form of ammonia in water.

Ammonia nitrogen (nh3-n) is both in the form of ammonium salt (NH4+) and free ammonia (NH3), and the proportion depends on the PH value of waste water.

When the PH value is high (alkaline), the proportion of free ammonia (NH3) is high;

When PH value is low (acidic), the ratio of ammonium salt (NH4+) is high, and the ratio of ammonium salt and free ammonia varies with the PH value of wastewater.

It is by taking advantage of this characteristic of ammonia nitrogen that people constantly seek new ways to remove ammonia nitrogen.

Coal chemical wastewater reuse equipment

A kind of high efficiency deamination assistant developed by our company contains a large number of O, H, OH, CH, CH2 and other atoms and ionic active groups, which can easily convert the ammonium salt and other organic amines in the remaining ammonia water into free ammonia to the maximum extent under the catalytic action.

At the same time, the partial pressure of ammonia in ammonia and other mixed gases can be minimized, and the desorption process and transfer rate of free ammonia released from the residual ammonia water can be accelerated, so that the converted free ammonia can be separated from the wastewater quickly and fully, and ammonia water or sulfate amine can be recovered.

High efficiency denitrification AIDS also have strong REDOX effect. Under the physical and chemical effects of high efficiency denitrification AIDS, free ammonia, other nitrogen-containing substances (nitric acid, salt, etc.) and organic amines can be converted into NH3, NH2, NH, NO and NO2 together, and then become harmless N2 after REDOX.
