摘要：

The　effect　of　different　organic　matters　on　nitrogen　removal　performance　of　anammox　coupling　heterotrophic　denitrification　process　was　investigated　by　continuous　cultivation　and　serum　bottle　batch　tests.　In　view　of　TN　removal　rate,　the　results　showed　that　the　sequence　of　these　orgnic　matters＇　influence　on　the　coupling　reactor　was　(from　minimum　to　maximum):　sodium　benzoate,　o-dihydroxybenzene,　m-dihydroxybenzene,　sodium　propionate,　sodium　acetate;.　sodium　benzoate,　o-dihydroxybenzene,　m-dihydroxybenzene,　sodium　propionate　and　sodium　acetate　have　a　little　impact　on　the　anaerobic　ammonia　oxidation　bacteria.　Phenol　denitrifying　bacteria　could　use　sodium　benzoate,　o-dihydroxybenzene,　m-dihydroxybenzene,　sodium　propionate　and　sodium　acetate　as　electron　donor　for　denitrification.　Different　organic　matters　had　different　influences　on　phenol　denitrifying　bacteria　and　then　affected　the　cooperative　and　competitive　relationship　between　phenol　denitrifying　bacteria　and　anaerobic　ammonia　oxidation　bacteria.　Benzoic　acid　was　the　possible　product　of　phenol　degradation.　©,　2015,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
