摘要

The effects of 2,6-DCP on excess sludge reduction and COD removal effi-ciency, and the distribution of 2,6-DCP between wastewater and activated sludge were investigated in laboratory batch experiments. The results confirmed that 2,6-DCP was an effective chemical in limiting the sludge growth which was able to reduce sludge growth rate by around 43.27% at 2,6-DCP dosage of 20 mgL-1 with the COD removal efficiency decreased by 6.25%. An average of 81% of 2,6-DCP in the influent was still persistent in the effluent independent of the influent concentration, whereas between 6.51% and 30.53% was adsorbed to the activated sludge.
