If it is discharged into the environment without treatment, the ammonia dissolved in the wastewater will volatilize into the atmosphere, resulting in a high concentration of ammonia in the factory area, and the inhalation of large amounts by workers and surrounding residents will seriously damage their health. It is necessary to take effective measures to remove ammonia. Ammonia in charcoal wastewater. Although some research institutes have proposed to use MPA method and osmotic membrane technology to treat pollutants in semi-coke wastewater, this technology has a better effect on the treatment of phenols in semi-coke wastewater, while the treatment of ammonia in semi-coke wastewater Only 50% can be removed, and the removal ability is limited. For this reason, it is necessary to propose a more advanced treatment device to strengthen the treatment of ammonia in semi-coke wastewater.
