Abstract
The invention provides a biochemical treatment process method of acrylic ester wastewater. The acrylic ester wastewater with high COD (Chemical Oxygen Demand) and high slat content produced by production equipment is pretreated by using a wastewater pretreatment system (I) and enters a primary biochemical treatment system (II) for step anaerobic and aerobic biochemical treatment; the wastewater subjected to the step treatment enters a secondary biochemical treatment system (III) for secondary anaerobic and aerobic biochemical treatment and then enters a purification treatment system (IV) for removing sludge and organic pollutants; and finally a small part of wastewater reaching the standard is fed back to the wastewater pretreatment system (I) for recycling and mostly is discharged. By adopting a specially-screened and domesticated high-efficiency microbial strain to treat the acrylic ester wastewater, the biochemical treatment system can thoroughly degrade the acrylic ester wastewater and has no secondary pollution; in the step of flocculation precipitation, clean water treated by the purification treatment system reflows to the pretreatment system for secondary utilization; and compared with a method for treating the wastewater by incineration, the invention can save large amount of fuels and steam and has remarkable economic benefits.
