研究采用三阶段递增负荷的方法，启动生物除磷SBR反应器。反应器启动分三个阶段，第一阶段历时16 d，进水COD和磷酸盐浓度分别为100 mg/L和5 mg/L；第二阶段历时16 d，进水COD和磷酸盐浓度分别为200 mg/L和7.5 mg/L；第三阶段历时19 d，进水COD和磷酸盐浓度分别为300 mg/L和10 mg/L。实验结果表明，在各阶段转换之后，反应器处理效果出现了7d左右的适应期。适应期之后COD的去除效果提升较快，而磷酸盐去除效果提升较慢。反应器启动过程中未出现污泥膨胀现象，并驯化出了厌氧释磷-好氧吸磷的生物除磷系统特征。反应器启动历时51 d，最终的COD去除率保持在85%左右，而磷酸盐去除率保持在81.2%左右，出水磷浓度保持在2 mg/L以下，处理效果良好，反应器启动成功。

Biological phosphorus removal (BPR) sequencing batch reactor (SBR) was startup with increasing loading in three-stage. Reactor was startup through three-stage. The first stage lasted 16d, influent COD and phosphate concentration were 100 mg/L and 5 mg/L.The second stage lasted 16d, influent COD and phosphate concentration were 200 mg/ L and 7.5 mg / L.The third stage lasted 19d, influent COD and phosphate concentration were 300 mg/ L and 10 mg / L. The experimental results showed that the reactor treatment effect appeared adaptation period about 7d after stage changing. After the adaptation period, the COD removal effect enhanced rapid, and phosphate removal effect enhanced slower. Sludge bulking did not appear during reactor startup.And the biological phosphate removal system characteristic that anaerobic phosphate releasing and aerobic phosphate removing was domesticated.SBR reactor startup lasted 51d. The final COD removal remained at around 85%, while phosphate removal remained at around 81.2%.The effluent phosphate concentration was at 2mg / L or less. The reactor treatment effect was good and SBR reactor startup was successful.
