How to Treat Ammonium Chloride Wastewater, We Focus on its Treatment Methods:
1Membrane Separation Technology
A method of ammonia nitrogen removal utilizing the selectivity of membrane permeation. This method is convenient to operate, boasts a high ammonia nitrogen recovery rate, and generates no secondary pollution. For instance: ammonia nitrogen removal by gas-water separation membranes. Ammonia nitrogen exists in water in an ionization equilibrium, and its concentration...PHIncreased, ammonia in waterNH3The shape ratio increases under suitable temperatures and pressures.NH3The gas and liquid phases have reached equilibrium. According to the principle of chemical equilibrium shift, i.e.,吕.Chadri(A.L.LEChatelier)Principles. In nature, all balance is relative and temporary. Chemical equilibrium can only be maintained under certain conditions: "If one of the conditions of the equilibrium system is changed, such as concentration, pressure, or temperature, the equilibrium will shift to counteract this change." Following this principle, the following design concept was developed: On one side of the membrane is a high-concentration ammonia-nitrogen wastewater, while on the other side is an acidic aqueous solution or water. When the temperature on the left side isT1>20℃,PH1>9,P1>P2Maintain the pressure differential, then the free ammonia in the wastewaterNH4+,Becomes ammonia moleculesNH3,And then diffuses through the liquid-side interface to the membrane surface, where it crosses the membrane pores under the action of the partial pressure difference across the membrane, entering the absorbent liquid and rapidly interacts with the acidic solution.H+React to form ammonium salts.
2、MAPDeposition Method
Primarily utilizing the following chemical reactions:Mg2++NH4++PO43-=MgNH4PO4
In theory, adding phosphates and magnesium salts to wastewater containing high concentrations of ammonia-nitrogen at appropriate ratios...[Mg2+][NH4+][PO43-]>2.5×10–13Magnesium Ammonium Phosphate can be produced(MAP)Removes ammonia nitrogen from wastewater.
3Chemical Oxidation Method
A method for directly oxidizing ammonia nitrogen to nitrogen gas using a strong oxidizing agent for removal.
