Ammonia nitrogen wastewater is a common industrial wastewater, mainly used in fertilizer, petrochemical, pharmaceutical and other industries. The discharge of ammonia nitrogen wastewater will cause serious pollution to the water environment, affecting the water ecological balance and human health. Therefore, effective treatment of ammonia nitrogen wastewater is crucial.
Electrolytic ammonia nitrogen wastewater treatment process
Pretreatment: Firstly, the ammonia nitrogen wastewater is pretreated to remove impurities such as suspended solids and organic matter to reduce the impact on the subsequent electrolysis process.
Electrolysis reaction: The pretreated ammonia nitrogen wastewater is passed into the electrolyzer, and the electric energy is provided through the DC power supply, so that an electric field is formed between the anode and the cathode. Under the action of an electric field, the ammonia nitrogen in the ammonia nitrogen wastewater undergoes an electrolysis reaction and is converted into nitrogen and water.
Separation & **: After the electrolysis reaction, the ammonia nitrogen in the wastewater is converted into nitrogen and water, the nitrogen escapes from the wastewater and the water remains in the wastewater. The nitrogen is separated from the wastewater through the gas-liquid separator, and the nitrogen is utilized.
Post-treatment: Post-treatment of electrolyzed wastewater, such as neutralization, sedimentation, etc., to ensure that the wastewater meets the discharge standard.
