| 摘 要： | 初步实验证实螯台球菌(Chelatococcus daeguensis)TAD1在高温下具有异养硝化-反硝化的能力,为验证其可应用性,采用曝气生物滤池工艺,研究了TAD1在温度为50℃的异养硝化-反硝化性能.结果表明,TAD1在曝气生物滤池中可同时进行好氧反硝化和异养硝化.当分别以硝氮、氨氮及硝氮和氨氮为氮源时,12 h的氮去除率均达到100%,氮的去除能力分别为12.67 mg.L-.1h-1、3.62 mg.L-.1h-1及16.53 mg.L-.1h-1.虽然在脱氮过程中,亚硝盐在6 h迅速积累到76 mg.L-1(硝氮为氮源)和52.6 mg.L-1(硝氮和氨氮为氮源),但在随后的几个小时内又快速降低至0(检测限之外).因而,TAD1具有应用于高温生物脱氮工艺的能力和优势. |

| Abstract: | Previous studies demonstrated that Chelatococcus daeguensis TAD1 exhibited an ability of heterotrophic nitrification-denitrification at high temperature.To verify its applicability,the performance for heterotrophic nitrification-denitrification at 50 ℃ was studied using an aerating biofilter process.Results showed that TAD1 simultaneously aerobically denitrified and heterotrophically nitrified in the biofilter.When using NO-3-N,NH+4-N and NO-3-N plus NH+4-N respectively as nitrogen source,the corresponding nitrogen removal capacity was 12.67 mg·L-1·h-1,3.62 mg·L-1·h-1 and 16.53 mg·L-1·h-1,and all the nitrogen removal rates reached 100% after 12 h.Although NO-2-N accumulated quickly to 76 mg·L-1(NO-3-N as nitrogen source) and 52.6 mg·L-1(NO-3-N plus NH+4-N as nitrogen source) during the denitrification,both of them decreased to zero(not detected) in the following hours.Thus,TAD1 possesses ability and advantage in its application to the biological denitrification process at high temperature. |
