Abstract
The bio-drying characteristics of paper mill sludge (PMS) and its influencing factors were inves- tigated in a self-designed experimental equipment. The following factors, such as temperature, pH, moisture content (MC) , volatile solids (VS) , ATP content, and quantity of amylolytic bacteria, and so on, were select- ed as the main factors to study the raw material mixture ratio and parameters during the hio-drying treatment process. The orthogonal experiments indicated that the optimal conditions were as followings: starch (25 g/500 g), sawdust (40 g/500 g), inoculation (15.0 mL/500 g) and potassium phosphate monobasic(5 g/500 g). The factors,including the temperature, pH value, moisture content, volatile solids, ATP content, and quantity of amylolytic bacteria, could be interpreted as the evaluating parameters of the bio-drying of PMS. The temperature of bio-drying materials could quickly attain 47.8 ℃ under the optimized conditions, and with a bio-drying period of 7 days, the output MC and VS could be reduced to 50.3% and 49.5% , respectively.关键词
