摘要：
The experiment on phosphorus recovery in PTMEG wastewater by crystallization was studied. The influences of molar ratio, precipitation time, stirring speed on the amount of crystals and structure characterization have been studied. The results indicated that under molar ratio 1.5:1, stirring speed about 200r/min and precipitation time 2h, PO43- removal ratio above 85%, the morphology of obtained crystals was related to the stirring speed and the X-ray diffraction pattern showed that the crystals had a high purity.
