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-1·h-1、3.62 mg·L-1·h-1及16.53 mg·L-1·h-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 NO3--N, NH4+-N and NO3--N plus NH4+-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 NO2--N accumulated quickly to 76 mg·L-1 (NO3--N as nitrogen source) and 52.6 mg·L-1 (NO3--N plus NH4+-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.
