文摘

A method is proposed to improve settleability of sludge water from waterworks. Combining ultrasound pretreatment and chemical re-flocculation is studied. Ultrasound treatment is capable of destroying extracellular polymeric substances. The operating parameters to achieve the optimal settling effect are obtained.
