There are about 2000 chlorine ions in the wastewater, and there is no effect of blowing off with ammonia nitrogen stripping tower.

According to the 2009 report "the influence of chlorine ions in water on the determination of ammonia nitrogen and elimination", when the concentration of chlorine ions is greater than 1100mg / L, ammonia nitrogen blowing tower data has exceeded the permissible range of standard samples, and the higher the concentration of chlorine ions, ammonia nitrogen blowing tower ammonia nitrogen detachment of the effect of the worse. When the chlorine ion content reaches 2000mg/L, the effect of ammonia nitrogen blow-off tower will be weakened by 77.9%.

The U.S. Defense Environmental Protection Agency has released a research report mentioned that the ammonia nitrogen blowing off tower treatment of wastewater containing a high concentration of chloride ions, the atmosphere has less influence on the chloride ions, but the tower's copper catalyst on the chloride ions adsorption ability is strong, easy to lead to catalyst poisoning, thus reducing the removal efficiency of ammonia nitrogen.
