| 摘 要： | 为了提高反硝化除磷工艺的脱氮除磷效率,以反硝化除磷污泥为研究对象,采用静态试验进行对比研究,考察碳源浓度对缺氧反硝化聚磷的影响.结果表明:当缺氧段初始碳源浓度为10.0 mg/L时,亚硝酸盐积累严重,反硝化聚磷受到抑制；当缺氧段初始碳源浓度由24.6 mg/L上升至176.8 mg/L时,随着碳源浓度的增加,反硝化速率...

| Abstract: | To improve the nitrogen and phosphorus removal efficiency,the effect of carbon source concentration on denitrifying phosphorus removal under anoxic condition was investigated by parallel batch experiments.The results indicate that when carbon source concentration is about 10.0 mg/L,phosphorus uptake is inhibited by nitrite accumulation.As carbon source concentration increases from 24.6 mg/L to 176.8 mg/L,the denitrification rate goes up.But the specific phosphorus uptake amount and the ratio of phosphorus r... |
