Effect of Fe on Nitrogen Removal Rate and Microbes of Anammox
Keyword(s):
With the anammox sludge as the inoculation sludge, the effect of different concentrations of Fe2+ and Fe3+ on the denitrification performance of the anammox reaction was explored by setting a control experiment.The results showed that when the Fe2+ concentration was 0.08mmol/l, the reactor had the best removal efficiency, the removal rate of NH4+-N was 89.14% after 60h, and the removal rate of NO2--N was 85.9%. The positive effect of Fe3+ on the anammox reaction was similar to that of Fe2+. From reading the literature, it can be known that Fe has a positive impact on anammox microorganisms in three aspects by promoting microbial enrichment, promoting the production of functional enzymes, and promoting microbial granulation.
