How is acrylic resin wastewater treated?

When producing acrylic resin, a large amount of acrylic resin wastewater will be produced, which needs to be treated through reasonable acrylic resin wastewater treatment technology, industrial additives Let’s show you how to treat this type of chemical wastewater.

Acrylic resin wastewater enters the regulating tank to adjust water quality and quantity. While homogenizing and equalizing, chemicals can also be added to adjust the pH of the wastewater. The acrylic resin wastewater then enters the coagulation tank. In the sedimentation tank, an appropriate amount of coagulant is added to the acrylic resin wastewater, and it is stirred by an impeller to fully contact and react. Then, the floc pollutants are separated through the sedimentation tank to improve the biodegradability of the wastewater, and then undergo biochemical treatment.

Acrylic resin wastewater enters the hydrolysis acidification tank to degrade part of the COD, degrade macromolecular pollutants into small molecule pollutants, and improve the biodegradability of acrylic resin wastewater. Subsequently, respectively Enter the anaerobic tank and the aerobic tank for reaction.

Anaerobic biological treatment can choose upflow anaerobic sludge bed reactor (UASB), anaerobic granular sludge expanded bed reactor (EGSB), internal Circulating anaerobic reactor (IC) and other processes; subsequent aerobic biological treatment can use sequential batch activated sludge process (SBR), oxidation ditch, contact oxidation tank and other processes. Coagulation sedimentation, sand filtration, membrane bioreactor (and other processes) can be used for advanced treatment; according to water needs, nanofiltration and reverse osmosis can be used for reuse.

Acrylic resinWastewater treatment technology mostly adopts “pretreatment + anaerobic + aerobic” combined process for treatment. Compared with a single anaerobic or aerobic treatment, the operation is stable. The specific process should be analyzed to determine a reasonable and economical acrylic resin wastewater treatment technology based on water quantity and quality, change patterns, drainage direction, discharge standards, treatment extent, etc.
