Comparison of Different Pretreatments for Hydrolysis of Residual Activated Sludge
摘要
Abstract
Pretreatments promote the hydrolysis of sewage sludge to improve the dehydration, anaerobic digestability and reduction of sludge. In this paper, the effects of four pretreatment processes including heating, alkalization, microwave and ultrasound on hydrolysis of residual activated sludge were compared to explore some pretreatment processes with higher efficiency and lower cost. The results showed that the promotion effect of heating and alkalization were significantly higher than that of microwave and ultrasound. Especially alkalization had the highest hydrolysis efficiency, by which the maximum increase of SCOD was up to 16. 8 times, meanwhile the maximum reduction of SS and VSS were 34% and 41% respectively.关键词
