Abstract

Provided is a process for treatment of at least one wastewater stream from an acrylic acid and/or acrylate production plant. The process for treatment comprises the steps of: (a) introducing the least one wastewater stream from the acrylic acid and/or acrylate production plant into a bioreactor (510), (b) reacting the at least one wastewater stream in the bioreactor (510) under conditions of anaerobic microbiological decomposition of undesired organic components in the presence of at least one microorganism suitable for decomposition of undesired organic components to afford methane and carbon dioxide, (c) discharging from the bioreactor (510) a treated wastewater stream depleted in undesired organic components relative to the at least one wastewater stream introduced into the bioreactor (510), and (d) incinerating a methane-and carbon dioxide-containing product gas stream discharged from the bioreactor (510), in the incineration plant (512) with an incineration air stream and an optional auxiliary fuel stream.
