DXS Ammonia absorber tower equipment

Equipment overview:

Ammonia nitrogen wastewater source and a big emissions, such as chemical fertilizers, coking, petrochemical industry, pharmacy, food, landfill all produce the large amount of high concentration of ammonia nitrogen wastewater. The large amount of ammonia nitrogen wastewater into a water eutrophication water caused not only caused by water, black smelly, and will increase the difficulty of the water treatment and cost, and even to the crowd and biological produce poisonous effect. Although the treatment of ammonia nitrogen wastewater treatment methods are various, but it is not a simple process, to give consideration to the saving investment, mature technology, control convenient and no secondary pollution to aspects of the technology.

I company developed the ammonia nitrogen treatment system through the will to remove ammonia nitrogen and absorption tower purification a number of technical combination rises, deal with different concentration of ammonia nitrogen wastewater, can will 10000 mg/L above the ammonia nitrogen wastewater treatment to emissions requirements. Treatment of ammonia nitrogen in 15 mg/L the following, to the national level 1 emission standard. Is a simple process, to give consideration to the saving investment, mature technology, control convenient and free of secondary pollution characteristics of ammonia nitrogen treatment system. Traditional ammonia nitrogen to remove out of air into the atmosphere with ammonia, still easy to cause secondary pollution, my company in ammonia nitrogen to remove tower and the absorption tower after setting, so that the row of the atmosphere for air to purified air, no pollution.

Areas of application: 1. The medicine, pesticide chemical wastewater; 2. The landfill leachate; 3. Fertilizer production wastewater; 4. Coking industry wastewater; 5. Rare earth smelting waste water; 6. Life sewage, etc.

Design principle:

Ammonia nitrogen in waste water by ammonium main (NH4 +) and free ammonia (NH3) state is, the balance between the shown below: NH3 + H2O-NH4 + + OH-the relationship between the influence by the pH value, when high pH value, the balance move to increase the proportion of free ammonia. Normal temperature, when the pH value of 7 about ammonia nitrogen to ammonium most state is, and pH of 11 or so, free ammonia roughly 98%, free ammonia to escape from the water easily, such as to aeration words, can make ammonia to escape from the water, among them, the pH is key effect.

Different pH, temperature of ammonia nitrogen dissociation rate (%)
