| 摘 要： | 以酒仙桥污水厂的二级处理出水为研究对象，采用中试规模的臭氧／活性炭／反硝化生物滤池工艺进行生物脱氮，重点研究了反硝化生物滤池采用连续流自然挂膜法的启动速度和启动效果，以及碳源投量对总氮去除率的影响。结果表明：反硝化生物滤池是实现污水深度处理的有效手段，当外加乙酸钠作碳源并使C／N〉8时，对TN的去除率能达到80％以上；下向流反硝化生物滤池的生物量主要集中在滤池的上半段，对去除TN的贡献率可达65％。 |

| Abstract: | A pilot scale experiment of ozone/activated carbon/denitrifying biofilter was conducted for biological nitrogen removal from the secondary treatment effluent of Jiuxianqiao WWTP. The start-up speed and efficiency of continuous-flow natural biofilm formation mode used by the denitrifying biofilter as well as the effect of carbon source dosage on the removal rate of total nitrogen were investigated. The results show that the denitrifying biofilter is an effective way to achieve the advanced wastewater treatme... |
