In our workshop, there is a wastewater storage tank that remains unused all the time; its contents are quite complex. How should it be dealt with?

Since the reflux liquid from the reflux tank at the top of the stripper keeps flowing in, there is a large amount of difficult-to-treat substances such as ammonia nitrogen, resulting in a complex composition. Attempts have been made to address this issue, but it’s very difficult to control the operations inside the tower. What should be done? Tests have shown that the compositions of the two storage tanks are not very different. It has also been blended in small amounts for treatment, but it’s not easy to operate. Sampling data for Tank A on a certain day: Ammonia nitrogen: 2157.5; Ammonia nitrogen: 2066.33. Sulfides: 327.5; Sulfides: 375.38. COD: 9052.8; COD: 10051. Sampling of wastewater from the recirculation tank on the same day: Ammonia nitrogen: 2056.32; Sulfides: 423.273. COD: 14081.28. {Note: Tank A remains stationary, while Tank B has continuous inflow and outflow; only a small portion of the water in the recirculation tank flows into Tank A.} This ultimately led to the deterioration of the water quality in Tank A, making it difficult to treat! }

It has also been blended in small amounts for treatment, but it’s not easy to operate. After mixing, the amount of ammonia gas is too high, making it difficult to control the temperature later on!

A tank can be used to hold it; ferrous sulfate can be added, and the flow of air should be even. It is advisable to heat the mixture as well, until its color turns earthy yellow, after which it can be discharged into wastewater. However, the odor pollution at the site is quite severe; be careful.
The method mentioned upstairs seems a bit difficult; it’s not convenient to use, is it? Is there a better way to handle this? Thank you all!
Don’t always let the liquid in the reflux tank flow back to the tower; it’s better to return an appropriate amount of liquid. Your installation should have a line for returning liquid to the tank, right?
