摘要:

将已筛选出的恶臭假单胞菌接种于曝气生物滤池中,模拟该系统对含Hg2+废水进行脱氮处理,重点考察碳源、碳氮比、NH4+-N初始质量浓度、水力停留时间(HRT)、气水比、络合剂(EDTA和柠檬酸钠)等对脱氮效果及Hg2+浓度变化的影响。研究发现Hg2+对好氧反硝化菌有刺激作用,促进了反硝化进程,而且Hg2+的脱除与反硝化是同步进行的。

关键词: 好氧反硝化, Hg2+, 曝气生物滤池

Abstract:

The selected Pseudomonas putida should be inoculated in the biological aerated filter,simulating the system for the denitrifying treatment of the wastewater containing mercury ions.The influences of carbon source,C/N,NH4+-N concentration,HRT,gas-water ratio and complexing agent(EDTA,Na-citrate) on denitrification effectiveness in the biological aerated filter are investigated emphatically.It is found that the mercury ion could stimulate the aerobic nitrobacteria to promote denitrification,and that the removal of Hg2+ and denitrification are conducted simultaneously.

Key words: aerobic denitrification, mercury ion, biological aerated filter
