Iron oxide pigment production involves a complex chemical process where iron reacts with nitric acid and sulfuric acid. After multiple reactions and treatments, various pigments such as iron oxide red, yellow, and black are produced. However, this process generates a significant amount of ammonium ions (NHâ‚„âº), resulting in high ammonia nitrogen levels in the wastewater. Additionally, the pH of the wastewater is very low, and it contains high concentrations of Fe²⺠and Fe³âº, which can cause severe environmental pollution if not properly treated before discharge.
Our company has developed an advanced high-concentration ammonia-nitrogen wastewater treatment system. This system utilizes an efficient stripping technology, with a gas-liquid ratio maintained around 5500, and the pH controlled at approximately 11.5. At temperatures above 25°C, the system can effectively treat wastewater with ammonia nitrogen concentrations ranging from 2000 to 4000 mg/L, achieving a removal rate of over 90%.
The system is equipped with a comprehensive control system that includes a pH meter, flow sensor, liquid level controller, solenoid valve, and control cabinet. These components provide real-time digital monitoring on the interface, allowing operators to easily track operational conditions and receive fault alerts for prompt maintenance. The system can be configured to operate manually, semi-automatically, or fully automatically based on customer needs.
Key features of our iron oxide pigment wastewater treatment process include:
1. A combined treatment process that efficiently handles wastewater with varying concentrations, achieving high ammonia nitrogen removal rates and meeting national first-class emission 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, with treatment capacities reaching up to 4000 mg/L of ammonia nitrogen.
3. All 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 even under harsh conditions.
