Effects of wastewater treatment processes on the sludge reduction system with 2,4-dichlorophenol: Sequencing batch reactor and anaerobic-anoxic-oxic process

•Effects of 2,4-dichlorophenol on two wastewater treatment processes were studied.•2,4-Dichlorophenol led to similar sludge reduction on two processes.•Sequencing batch reactor was more likely to retard an increase of sludge volume index.•2,4-Dichlorophenol did not dramatically affect microbial comm...
