摘要：In this study, the orthogonal test method was applied to optimize the operational parameters in the excess sludge homogenization process. The sludge concentration, homogenization speed and homogenization time were used as independent variables, and the Disintegration Degree of Chemical Oxygen Demand (DDCOD) was used as the dependent variable. The results showed that, when DDCOD was considered as the primary index, three factors including homogenization time, homogenization speed and sludge concentration in sequence had important influence. When the DDCOD maximum value was 40%, the optimal conditions were: sludge concentration of 8000 mg/L, homogenization speed of 19000 rpm, and the homogenization time of 35 min.
