High concentration ammonia nitrogen wastewater treatment is a critical process in industrial waste management. This type of wastewater typically comes from chemical plants, metallurgical industries, and circuit board etching facilities. The ammonia nitrogen exists mainly in the form of ammonium salts or NH4OH, with concentrations ranging between 1 to 50 g/L. Direct discharge of such highly polluted water is strictly prohibited due to its severe environmental impact. Traditional biological methods are often ineffective for treating high ammonia nitrogen wastewater, making advanced technologies essential.
Our company has developed an advanced high-concentration ammonia nitrogen wastewater treatment system that utilizes a high-efficiency stripping process. This system operates with a gas-liquid ratio of approximately 5500, maintaining a pH level around 11.5. At temperatures above 25°C, it can effectively treat wastewater with ammonia nitrogen concentrations as high as 2000–4000 mg/L, achieving a removal efficiency of over 90%.
The system is equipped with a comprehensive control system, including a pH controller, flow sensor, liquid level meter, solenoid valve, and control cabinet. All operational parameters are displayed digitally on the interface, allowing operators to monitor the process easily. The system also features fault alarms for quick troubleshooting and maintenance. It can be configured to operate manually, semi-automatically, or fully automatically, depending on the user's needs.
Key features of the treatment process include:
1. Integration of multiple treatment stages allows efficient removal of ammonia nitrogen across various concentration levels, ensuring compliance with national first-class discharge standards (≤15 mg/L).
2. The system is scalable, capable of handling flows from several tons per hour up to hundreds of tons per hour. It can treat concentrations as high as 4000 mg/L, meeting strict environmental regulations.
3. The equipment is constructed using corrosion-resistant materials such as FRP, carbon steel with anti-corrosion coating, and stainless steel, ensuring long-term durability and performance in harsh environments.
