| 摘 要： | 针对前置反硝化(DN)-硝化(CN)生物滤池工艺进行碳(COD)、氮、磷平衡分析,建立了该工艺的物料衡算方法。分析结果表明:DN池中反硝化的碳源主要是甲醇,占DN池反硝化碳源量的70.8%。入流总氮中有13.7%通过CN池的同步硝化反硝化过程去除;入流COD中有46.4%通过CN池中异养菌的好氧氧化去除;入流磷总量约有75.9%被微生物利用。CN池中硝化过程耗氧量为29.0%,占供氧量的比例最大。 |

| Abstract: | Carbon(COD),nitrogen and phosphate material balances of the process of pre-denitrification and nitration biological filter were investigated.The methods for calculating material balances of the process were established.The results indicated that the methanol was the main carbon source for denitrification in DN filter,which accounted for 70.8% of the total carbon source consumed in the denitrification process of DN filter.13.7% of the influent total nitrogen was removed by SND process of CN filter.46.4% of t... |
