     anammox coupling with nitrate reduction under various electron donors was studied using sludge acclimatized to have anammox and denitrification activities. due to a deficiency in electron donors for no-3 reduction, anammox activity in an inorganic medium containing no-3 and nh+4 was lower than that in no-2 and nh+4. anammox could use no-2 competitively against denitrifiers under a very limited no-2 concentration, and additions of swine wastewater or acetate stimulated anammox activity in an inorganic medium containing no-3 and nh+4 with no inhibition effects. however, a high concentration of swine wastewater caused an exponential increase in denitrification activity. the addition of hydrogen and iron stimulated anammox activity in an inorganic medium containing no-3 and nh+4, but iron showed an inhibitory effect on anammox in a medium containing no-2 and nh+4. hydrogen was shown to be advantageous since it did not increase denitrification even when its addition was increased.
