文摘

Sawdust conditioning (SC) is feasible in deep-dewatering for sludge incineration. SC can decrease sludge moisture content, but finitely accelerate dewatering rate. SC can efficiently accelerate sludge cake further dewatering via air drying. SC improves the calorific value of sludge cake and makes incineration profitable.
