Treatment method of acrylic acid and ester sewage

The invention relates to a treatment method of acrylic acid and ester sewage, according to the practical experience of sewage containing formaldehyde, amide, pyrrolidone and glycerol, a technical process of'UV strong oxidation pretreatment + Fenton fluidized catalytic oxidation reaction + IC anaerobic reactor 'is selected, and the sewage is generally treated and operated by adopting a physical and chemical treatment method and a biochemical treatment method in a combined manner. The operation cost can be effectively saved, and management control is relatively simple. An electromagnetic flowmeter and a pneumatic adjusting valve are arranged on a water inlet pipeline and an outer backflow pipeline of the IC anaerobic reactor, flow is controlled through linkage of the pneumatic valve, stable operation of the system is guaranteed, impact resistance is improved, and labor intensity of workers is reduced. A water inlet pipeline of the IC anaerobic reactor adopts an efficient ejector, it is guaranteed that sludge at
