从反硝化脱氮系统中筛选出一株高效反硝化功能菌FH2,经鉴定为蜡状芽孢杆菌,静态试验中,在NO_3~--N浓度为400 mg/L的条件下,该菌对NO_3~--N的去除率高达100%。以该菌作为生物强化菌源,进行生物强化反硝化试验研究,结果表明,在保证达到理想脱氮效果的条件下,生物强化工艺可承受的进水NO_3~--N浓度最高为340 mg/L,比普通工艺提高了100 mg/L,并且生物强化工艺的启动时间明显缩短,耐负荷冲击能力和运行稳定性得到明显增强,表明应用该优势菌进行生物强化反硝化脱氮具有可行性。

A strain with high performance of denitrifying function named FH2 was isolated from the denitrification system, and it was identified as Bacillus cereus. During the static experiments, the removal rate of NO3- - N was up to 100% under the concentration of 400 mg/L. As the inoculum, the FH2 strain was employed for bioaugmentation denitrification, and the results showed that under the ideal removal rate, the maximum influent NO3- - N concentration of the bioaugmentation denitrification system could reach 340 rag/L, 100 mg/L higher than the ordinary denitrification system. Besides, the start-up t...
