Activated Sludge Yield as Affected by the Addition of a Xenobiotic Substrate 何俊賢、張玉明

ABSTRACT

This research was to investigate the effects of a xenobiotic on the yield of the continuous-flow activated sludge which was fed a biogenic substrate. The xenobiotic used was 2,4-dichlorophenoxyacetic acid (2,4-D), while the biogenic substrate was made up with sucrose and peptone. The sludge retention time (θc) was controlled at 6 days and 10 days, the hydraulic retention time (HRT) was 8 hours. Experimental results showed that, 2,4-D was to decrease active sludge yield. The reduction of yield was proportional to input 2, 4-D concentration. The plausible explanation for this yield reduction is because for 2,4-D degradation at the presence of a biogenic substrate, energy is expenses is charged on metabolism of the biogenic substrate.

Keywords : Active sludge ; xenobiotic ; yield ; 2,4-D
