| 中文摘要 |
| 在悬浮污泥系统中,当pH、温度适宜,碳源无限制并采用单一类碳源时,反硝化速率和耗碳速率动力学呈零级反应。混合挥发性脂肪酸碳源的反硝化速率比组成它的单一脂肪酸的反硝化速率高。挥发性脂肪酸中,乙酸的反硝化速率最高。挥发酸的反硝化速率比相应的醇类为高。本文还讨论了降低反硝化系统碳源消耗、减少处理成本的方法。 |
| 英文摘要 |
| n a suspended sludge system, the rat6s of denitrifiCation and carbon uptake can follow a zero-order reaction when the carbon supply was from an unlimited,single kind of carbon source at a suitable PH and temperature. It was found that a mixed volatile fatty acid (VFA) C-source resulted in a higher rate of denitrifiCation than any of the individual VFA C-sources which formed the mixed one. Of the VFAs,acetate gave the highest rate of denitrification. The VFAs gave a higher rate of denittification than their corresponding alcohols. The means of reduCing the carbon consumption and the cost of treatttient in a denitrification system had been also discussed. |
