Anaerobic digestion of pesticide-plant wastewater

Lin, Chiu-Yue

AbstractExperiment on anaerobics digestion using an organic phophorus pesticideplannt wastewater containing a high percentage (62%) of acetate were conducted with chemostat-type digesters maintained at 35°C. The influent COD concentration was 9650 mg/liter. The digesters operated stably at the retention times of 15, 20 and 30 days, with COD removal efficiencies of 87·0, 89·4, and 91·5%, respectively. The biokinetic constants were νmax = 3·37/day ,Ks = 4077 mg COD/liter, Yg = 0·148 mg VSS/mg COD, and Kd = 0·050/day. Bacilli and sarcinae were the predominant morphological species and the dominance was independent of retention time. The optimal retention time was 15 days.
