Absorption and application treatment method for ammonia-containing tail gas

The invention discloses an absorption and application treatment method for ammonia-containing tail gas, comprising the following steps: a third-stage absorption column is pre-charged with deionized water, tail gas is subjected to countercurrent exchange absorption through spray absorption, and tail gas after absorption is qualified to be discharged. When the concentration of ammonium chloride in athird-stage absorption liquid reaches a specified value, third-stage absorption tail gas is subjected to re-absorption by a second-stage spray absorption column after passing through a pipe coil; after tail gas is subjected to countercurrent exchange absorption through spray absorption by the second-stage spray absorption column and the concentration of ammonium chloride in a solution in the absorption column reaches a specified value, second-stage absorption tail gas is transferred to a first-stage absorption column for spray re-absorption through a pipe coil; and ammonia-containing tail gasis subjected to countercu
