for treating real domestic wastewater. The system ran at 20 ℃, and the phosphorus removal efficiency kept above 90% steadily. Then the system ran in low temperature conditions (15, 10 and 5 ℃). The results show that the phosphorus release ratio at the four temperatures (20, 15, 10 and 5 ℃) is 358.5%, 358.5%, 247.8% and 209.1% with the VFAs usage ratio at 100%, 88.9%, 58.4% and 33.8% in each case......

precipitate can significantly reduce the carrier lifetime of multicrystalline silicon due to their Schottkydiode behavior in the silicon substrate. A 900 °C rap thermal process (RTP) phosphorus gettering anneal cannot be sufficiently effective to remove the Cu precipitates in these two regions. Key words: multicrystalline silicon; Cu precipitate; phosphorus gettering; defects; carrier lifetime 1......
