step three: the treated liquid containing the hydrated ammonia is sent into a reaction tank (3) through a wastewater sending pipe (8), and the wastewater sending pipe (8) and a discharge elbow (21) are plugged through an electromagnetic control valve;
step four: starting a reaction center column (4) and a plurality of reaction plates (5) through an electric cabinet (2), carrying out phonon resonance on the hydrated ammonia in a reaction tank (3), and separating the hydrated ammonia by keeping the resonance frequency away from the resonance frequency of water molecules;
step five: the separated hydrated ammonia is collected and discharged through a separator discharge pipe (7), then condensed and collected, and the waste water can be contacted with a reaction center column (4) and a reaction plate (5) by slowly rotating a reaction tank (3) and matching with a plurality of stirring sheets (17) at the bottom during separation;
step six: after separation is completed, an electromagnetic control valve of the discharge elbow (21) is opened, and wastewater separated in the reaction tank (3) is discharged from the discharge elbow (21).
