Seeking methods for treating iron-containing wastewater

The wastewater in my workshop is acidic, containing iron, ammonia, organic substances, and sodium chloride; I am seeking advice on methods for treating it. Iron concentration: 1.3%, ammonia concentration: 2.24%, HCl: 4%; it contains a small amount of solvent dichloroethane and organic suspended solids with a COD value of 30,000–40,000, and the water volume is approximately 15 T per day.
How high is the iron concentration? What is the ammonia concentration? What’s the COD? What are the standards for the water quality?

It now depends on the concentration of sodium chloride; iron ions can be removed by adjusting the alkalinity, and sodium chloride can also be removed through osmosis. The remaining water then enters the biochemical system.
What’s the situation with code 30000-40000?……
Is it wastewater from the chlor-alkali industry? How much water is there?
Special membrane separation technology can be used to recover and reuse the acid, remove iron and organic substances, and partially remove sodium chloride
I work with thiopropionic acid. The water volume is around 20 T per day.
Sodium chloride is saturated; trying to remove iron with alkali is quite difficult.
Centrifugal extractors are mainly used to deal with wastewater, and there are cases related to this type of wastewater for us.
