摘要：

In　order　to　study　the　feasibility　of　using　sponge　as　carrier　and　applying　it　for　ANAMMOX　research,　experiments　were　carried　out　in　an　up-flow　column　reactor　with　synthetic　high　nitrogen　wastewater　as　influent.　The　operational　results　showed　that　the　TN　removal　efficiency　as　high　as　75%　was　obtained　at　a　high　volumetric　loading　rate　of　3.5kg/(m3·d)　and　a　short　HRT　of　3.1　hours　with　the　synthetic　wastewater　as　the　influent.　At　steady　operation,　the　liquid　pH　value　in　the　bioreactor　was　alkaline.　The　ratio　of　NH4-N　removal,　NO2-N　removal　and　NO3-N　production　are　1:1.21:0.19.　Compared　with　other　carriers(Biofill　and　PVA-gel),　the　start-up　period　for　the　reactor　of　sponge　as　carrier　is　shorter,　and　the　operation　is　simple.　And　also　it　showed　potential　for　treatment　of　wastewater　with　high　concentrations　of　NH4-N　using　a　short　hydraulic　retention　time.
