| 摘 要： | 对好氧反硝化处理硝氮废水产生的中间气态产物进行了研究。结果发现系统的好氧反硝化会产生一定量的中间气态产物NO、N2O,但逸出量相对较少,在进水COD/N=10时,NO逸出0.43mg,占总脱氮量的0.17%,N2O逸出9.17mg,占总脱氮量的3.55%;进水COD/N=20时,NO逸出0.23mg,占总脱氮量的0.05%,N2O为0.78mg,占总脱氮量的0.17%。同时发现碳源是影响好氧反硝化进程的主要因素。

| Abstract: | The intermediates of aerobic denitrification were studied to treat wastewater containing nitrate.Results indicated that a quantitative intermediates such as NO and N2O would be generated in system of aerobic denitrification with relative small overflow.NO and N2O generated was 0.43mg and 9.17mg respectively when COD/N of influent was 10,covering 0.17% and 3.55% of total nitrogen removal;while NO and N2O generated was 0.23mg and 0.78mg respectively when COD/N of influent was 20,covering 0.05% and 0.17% of total nitrogen removal.Carbon source was found as the main factor to affect the process of aerobic denitrification. |
