Different factories have different processes, so there is no comparability.

In coking wastewater, phenols constitute the main component of COD, accounting for about 90%. For microorganisms, that is their food.

How do you think ammonia nitrogen and cyanide are organic substances? Did you study chemistry for nothing?

In coking wastewater, phenols are the main organic compounds, as is tar; however, tar can be separated more easily, while phenols are very difficult to remove. If phenol can be recovered, it is best to recover the acid first.
