| 摘 要： | 以初沉污泥厌氧水解／酸化产物为反硝化的碳源，进行了脱氮效果的试验研究，并和其它碳源的脱氮速率进行了比较．结果表明，初沉污泥水解／酸化产物的脱氮速率比城市污水、初沉污泥中的碳源的脱氮速率分别高出2倍和11倍，也比外加甲醇提高约1／3．因此初沉污泥水解／酸化产物是生物脱氮除磷系统一个经济有效的可替代快速碳源．

| Abstract: | Biological hydrolysis and acidgenesis of primary sludge to a carbon source which was used as in nitrogen-removal process to discuss the effect of denitrification and compare it with the effects of denitrification with other kinds of carbon sources. The experiment results showed that the denitrification rates with carbon from hydrolysis and acidogenesis process are three times and twelve times as much as denitrification rates when using wastewater and fresh sludge as the carbon source respectively. Moreover, the denitrification rate increased by 1/3, compared with the corresponding value with exogenous carbon source. As a result, it is safe to say that products from the primary sludge fermentation is the fast alternative carbon source for both denitrification and biological phosphorus removal. |
