It is necessary to determine what the main components of desulfurization wastewater are/then we can consider treatment methods:)

Is it discharged according to the standard or recycled. Also, are you talking about the desulfurization liquid coming out of the sulfur melting kettle? If so, it is recommended to mix it after cooling!
The desulfurization mentioned by the poster is NHD or tannin desulfurization. Basically, both of them are difficult to treat sewage. Today's sewage treatment is more effective and popular is biological treatment. If ammonia nitrogen and COD are high, it cannot be treated. The two desulfurization solutions mentioned above have relatively high values.
It is best not to do so. Generally, biological treatment is used for water treatment. The harmful components of the desulfurization liquid will kill microorganisms. Best to recycle.
First of all, it is necessary to determine the composition of the desulfurization liquid, especially the sulfur content, and the existence form of sulfur, such as sulfide ions, sulfate radicals or others. If the amount is large, you can consider recycling it. Sulfur is very valuable.
