【 摘 要 】

The paper deals with recovery of phosphorus from the liquid discharge from dewatered wastewater treatment sludge via electrodialysis. Using electrodialysis, phosphorus was transferred into concentrate, where phosphorus concentrated to673.6 mg/l (from the original value 79.87 mg/l). This enriched concentrate may be further processed, e.g. phosphorus can precipitate into the form of struvite.
