Degradation rate of the target by acclimated activated sludge is increased after successive acclimation. To find a way to further increase xenobiotic degradation rate by acclimated sludge, biogenic organics are chosen as supplemental substrates that may enhance vitality of the sludge. The objective of this study was to investigate the dosage and the combination dosage of biogenic substrates that were most beneficial to increasing xenobiotic degradation rates. The biogenic substrates were sugar and protein, represented with cane sugar and peptone, respectively. The dosages of biogenic supplementation were designed with the Box-Behnken method. Test results show that the best sugar and peptone dosage were 200 mg/l and 250 mg/l, respectively. The best dosage of combined sugar and peptone, however, were a concentration of sugar less than 200 mg/l, and peptone of higher than 250 mg/l.
