This study presented treatment of a high strength inhibitory acrylic acid wastewater by integrated anaerobic-aerobic processes. A novel scheme integrating anaerobic granular sludge blanket (GSB) reactor, aerobic carrier biofilm (CBR) reactor and activated sludge reactor (ASR) was tested. The laboratory trial showed that the GSB was able to degrade exceptionally high chemical oxygen demand (COD up to 32,420 mg/L) acrylic acid wastewater laden with 5% waste oil. Operated under a high volumetric loading (VLR) rate of 21.6 g/L·d, the integrated GSB-CBR-ASB achieved 99% of COD removal, of which 90% were removed by the anaerobic process and 9% by the aerobic processes. Full-scale implementation indicated comparable performance with overall removal up to 99%, thus meeting the discharge limits of 500 mg COD/L of public sewer. The integrated scheme was effective in which the anaerobic GSB functioning as a prime degrader that degraded most of the pollutants, while the aerobic CBR-ASB serving as a polisher that removed the remaining COD. With adequate microbial acclimation and granulation, the novel integrated scheme offers a resilient and robust treatment system for high strength inhibitory acrylic acid wastewater. © 2020 Elsevier B.V.Acrylic acid wastewater; Integrated treatment; Polisher; Prime degrader[SDGs]SDG6[SDGs]SDG7[SDGs]SDG9[SDGs]SDG11[SDGs]SDG12Activated sludge process; Carboxylic acids; Chemical oxygen demand; Wastewater treatment; Activated sludge reactors; Anaerobic granular sludge; Anaerobic-aerobic process; Anaerobic-aerobic treatment; Full-scale implementation; Industrial wastewaters; Microbial acclimation; Sustainable treatments; Industrial water treatment; acrylic acid; acrylic acid; acrylic acid derivative; acid; anoxic conditions; experimental study; granular medium; industrial waste; integrated approach; laboratory method; oxic conditions; sludge; wastewater treatment; aerobic granular sludge; anaerobic granular sludge; Article; chemical oxygen demand; degradation; feasibility study; pollutant; priority journal; process optimization; sewer; waste component removal; waste water; anaerobic growth; bioreactor; Acrylates; Anaerobiosis; Bioreactors; Waste Waterjournal article10.1016/j.scitotenv.2020.140323328063842-s2.0-85086903323WOS:000559085400003
