Background
The ammonia nitrogen refers to nitrogen existing in the form of free ammonia (NH3) and ammonium ions (NH4+) in water, the nitrogen content of animal organic matters is generally higher than that of plant organic matters, meanwhile, nitrogen-containing organic matters in human and animal feces are unstable and are easy to decompose into ammonia, therefore, when the content of the ammonia nitrogen in the water is increased, the compound nitrogen existing in the form of ammonia or ammonium ions is referred to as ammonia hydrate, namely non-ionic ammonia, wherein the natural surface water body and underground water body mainly contain nitrate nitrogen (NO3), and the ammonia nitrogen of the nitrogen water body existing in the form of free ammonia (NH3) and ammonium ions (NH4+) is referred to as ammonia hydrate, the non-ionic ammonia is a main factor causing aquatic organism toxicity, the ammonium ions are relatively basically non-toxic, the concentration of the non-ionic ammonia nitrogen is less than or equal to 1 mg/L, the ammonia nitrogen is a nutrient in the water body, and can cause the water eutrophication phenomenon and is a main oxygen-consuming pollutant in the water body, the method has the advantages of simple process, stable treatment effect, low capital cost and operation cost, and the air stripping method is a method for stripping free ammonia nitrogen from the waste water by utilizing the gas separation law (Henry law) through different gas partial pressures, and has the specific principle that the air stripping is used under the alkaline condition by utilizing the difference between the actual concentration and the equilibrium concentration of volatile substances such as the ammonia nitrogen and the like contained in the waste water, and the ammonia concentration in the gas phase is changed because the gas is continuously discharged in the air stripping process, so that the actual concentration is always smaller than the equilibrium concentration under the condition, and finally the ammonia dissolved in the waste water passes through the gas-liquid interface, NH3-N in the wastewater is removed, and air is often used as a carrier. Ammonia stripping is a mass transfer process, the driving force comes from the difference between the partial pressure of ammonia in the air and the balanced partial pressure equivalent to the concentration of ammonia in the waste water, the partial pressure of gas components in the liquid surface and the concentration in the liquid accord with the Henry's theorem, namely, a direct proportion relation, the practicability is strong, however, the PH value and the temperature of the waste water need to be accurately adjusted when ammonia nitrogen is treated by utilizing a stripping method, when the experimental PH value is 11, the removal rate of ammonia nitrogen in the waste water is the highest, and the temperature control of the PH value and the waste water by the existing stripping device is not comprehensive enough, so that the concentration of the ammonia nitrogen in the effluent is high, therefore, a multi-section ammonia nitrogen recovery device and a recovery system thereof are necessary to be provided, and the effect of high-efficiency recovery can be achieved.
