Effect of initial ratio of C/P and phosphate concentration on performance of aerobic phosphate reduction was studied by varied substrate condition. Results show that substrate condition has a significant effect on phosphorus removal efficiency. Too high or low initial ratio of C/P is all not propitious to phosphate reduction. Phosphate removal rate of SBBR achieves to the top tip on the initial C/P of 100, and the mean is 52.93%, which indicates that phosphate reduction bacteria are heterotrophic bacterium Besides, increase of initial phosphate concentration can improve the removal amount of phosphate with enough carbon source, moreover, a notable positive correlation exists between them and also between removal amount of phosphate and COD. Analysis of process applicability shows that phosphorus removal process of phosphate reduction is favor to treat human and animal excreta wastewater, sludge digested liquid, mustard tuber wastewater and so on enough carbon source of high phosphorus concentration wastewater.
