Abstract

The invention discloses a treatment technology used for acrylic acid and acrylate wastewater. The treatment technology comprises a regulation tank, a first ABR tank, a first SBR tank, a first intermediate tank, a second ABR tank, a second SBR tank and a second intermediate tank; and the wastewater is subjected to EMO composite microbial treatment in the regulation tank, then sequentially flows into the first ABR tank, the first SBR tank, the first intermediate tank, the second ABR tank and the second SBR tank to undergo biochemical treatments, and finally is discharged in a standard reaching manner through the second intermediate tank. The treatment technology used for acrylic acid and acrylate wastewater allows the COD removal rate to reach 99% and the ammonia nitrogen removal rate to reach 97%, and has the characteristics of high stability and strong operability.

Description

technical field [0001] The invention relates to the technical field of acrylic acid and acrylic acid esters, in particular to a treatment process applied to acrylic acid and acrylic acid ester wastewater. Background technique [0002] Acrylic acid and ester wastewater is a high-concentration, highly toxic, and complex-component organic wastewater that is difficult to treat. At present, the methods for treating acrylic acid and ester wastewater mainly include incineration, wet catalytic oxidation, biological methods, etc. [0003] At present, the mainstream method for treating acrylic acid and ester wastewater is still the incineration method, and some progress has been made in the catalytic wet oxidation method and biological method, while the development of other methods is relatively slow. The catalytic wet oxidation method has high treatment efficiency and fast speed; however, the specificity of the catalyst limits the popularization and application of this technology in ...
