title: [Anaerobic biological treatment of Lincomycin production wastewater].
abstract: The high-strength Lincomycin production wastewater containing toxic and refractory substances treated by lab-scale mesophilic UASB reactor was described. When the reactor was operated in influent COD 8000-14,000 mg/L and HRT 10 h, the volumetric loading rate and COD removal rate could reach 20-35 kg/(m3.d) and 50%-55%, respectively. The granular sludge might be formatted by using a bit longer acclimation time, adjusting and maintaining fairly high surface hydraulic loading rate of 0.2-0.4 m3/(m2.h), influent COD of 2000-3000 mg/L and sludge loading rate of 0.2-0.5 kg/(kg.d). The anaerobic kinetic constants of Vmax and Ks for the wastewater treatment were 1.3 d-1 and 8133 mg/L, respectively. The non-biodegradable substances accounted for about 30% of total COD, which was the important factor of relative low COD removal rate for the wastewater.
