| 内容記述 | A wastewater treatment plant with a large inflow of phosphorus (P) is a potential P source 12 that can act as an alternative to phosphate rocks and a renewable source of P. During 13 electrolysis with inert electrodes, hydroxide ions generated from the cathode cause calcium 14 phosphate (CaP) precipitation, and oxygen and hydrogen generated from the electrodes cause 15 thickening of the sludge by electroflotation in sludge treatment streams. However, these two 16 effects have not been achieved simultaneously because the precipitation of CaP requires 17 much more time than that required for thickening by electroflotation. In this study, an 18 electrolysis system that used an anode covered with bivalve shells was used. Batch 19 experiments were conducted and the results demonstrated that covering the anode with shells 20 resulted in their dissolution and that the calcium ions provided by this process considerably 21 enhanced P removal in the form of CaP, thereby shortening the time required for CaP 22 precipitation. In continuous experiments with excess sludge, electrolysis with shells 23 accomplished sludge thickening by electroflotation (the thickened sludge had 5.5 times the 24 total solids in the original excess sludge) and low relative phosphate-P concentrations 25 (0.0545–0.0812) in the effluent compared to the influent. This effect is attributed to CaP 26 precipitation. Additional mixing of the CaP precipitates in the effluent enhanced their 27 settleability. The results demonstrate that electrolysis using an anode covered with bivalve 28 shells simultaneously achieved CaP precipitation and sludge thickening. | |||||||||||||||
