Abstract:

It is an important prerequisite for proper disposal and resource utilization of sludge to improve its dewaterability with conditioning pretreatment. Conditioning based on flocculation is the most reliable and widely used technology for improving sludge dewaterability due to its significant effects and controllable costs. In addition, the combined flocculants can play a synergistic role and have more diverse functionality, which is a research hotspot of sludge dewatering. The current situation of sludge disposal and treatment, as well as the difficulties in sludge dewatering were introduced. The mechanism and application of various flocculants or their combined usage were elaborated. This paper is expected to provide theoretical basis and application reference for the utilization of flocculation-based technology to enhance sludge dewaterability.

Key words: sludge, dewatering, flocculation, combined usage of flocculants
