Treatment method of acrylic acid wastewater

The invention discloses a treatment method of acrylic acid wastewater, and belongs to the field of wastewater treatment method, according to the method, the acrylic acid wastewater is introduced to acoagulation reaction tank, so that most of the suspended impurities in the wastewater can be removed, and the sludge and water in the effluent after the coagulation reaction are separated by flowing through a sedimentation tank. The supernatant is introduced into a biochemical system, and the organic pollutants are degraded through one-stage continuous aerobic/ABR anaerobic/two-stage continuous aerobic/BAF aerobic, and the whole organic nitrogen of the wastewater is subjected to ammoniated, nitrated and denitrified reactions. The sediment sludge is subjected to external transportation treatment, the supernatant is discharged after reaching the standard. The biochemical combination process simultaneously ammoniates, nitrates and denitrifies the whole organic nitrogen of the wastewater, andtreats ammonia and nitroge
