In modern industrial production, wastewater treatment is a critically important environmental protection task. As one of the common pollutants found in wastewater, ammonia nitrogen poses significant threats to both the environment and human health if not effectively removed. Ammonia nitrogen treatment towers, as advanced wastewater treatment equipment, play a vital role in the field of industrial wastewater treatment thanks to their advantages such as high efficiency, cost-effectiveness, and ease of operation.

　　The basic principle of the ammonia-nitrogen treatment tower is to employ the stripping method: air is introduced into the wastewater, causing the dissolved free ammonia in the wastewater to cross the gas-liquid interface and transfer into the gas phase, thereby achieving the removal of ammonia nitrogen. This method enhances the efficiency of ammonia-nitrogen removal by increasing the gas-liquid contact area and extending the contact time. Meanwhile, the interior of the ammonia-nitrogen treatment tower typically features high-efficiency packing materials, which further increase the gas-liquid contact area and promote the volatilization and removal of ammonia nitrogen.

　　In practical applications, ammonia-nitrogen treatment towers offer significant advantages. They boast high removal efficiency, capable of reducing ammonia-nitrogen levels in wastewater to very low concentrations, thereby meeting the emission requirements set by environmental protection standards. These towers are easy to operate and require low maintenance costs, helping enterprises reduce their operational expenses. Moreover, this equipment exhibits broad applicability and can be used to treat various types of industrial wastewater containing ammonia nitrogen—from sectors such as fertilizers, petrochemicals, pharmaceuticals, coal mining, chemicals, and metallurgy.

　　However, when using ammonia-nitrogen treatment towers, it is also important to pay attention to certain issues. Since hardness ions (such as calcium and magnesium) present in wastewater tend to form precipitates under alkaline conditions, adhering to the inner walls of equipment and packing materials, regular cleaning of the equipment is necessary during operation to prevent scaling from affecting its normal performance and the efficiency of ammonia-nitrogen removal. Under low-temperature conditions, the stripping efficiency of ammonia nitrogen will significantly decrease; therefore, insulation measures or heating devices should be considered during equipment design to enhance the effectiveness of ammonia-nitrogen removal. To avoid secondary pollution caused by the direct release of stripped ammonia gas into the atmosphere, it is essential to equip the system with appropriate absorption and treatment devices for recovering and reusing the stripped ammonia gas.

　　In summary, the ammonia-nitrogen treatment tower, as an efficient wastewater treatment device, plays a vital role in the field of industrial wastewater treatment. Its high removal efficiency, low operating costs, and wide applicability make it an invaluable assistant for enterprises dealing with ammonia-nitrogen-containing wastewater. However, during operation, it is important to pay attention to issues such as equipment cleaning, thermal insulation measures, and ammonia gas recovery, in order to ensure the equipment’s proper functioning and its environmental protection performance. As environmental regulations become increasingly stringent and wastewater treatment technologies continue to advance, the ammonia-nitrogen treatment tower will play an even more significant role in the field of industrial wastewater treatment, contributing further to environmental protection and human health.
